Privacy Planting in Containers and Savory Herb

PLANT DOCTOR

Plants for Privacy in a Container
What do you do if you want a plant for privacy but there’s either not enough soil in that location or you’re in an apartment?
I’ve talked about big trees in pots with horticulturist, Adrian O’Malley from Plant of the Week, before, but it doesn’t have to be just about trees for privacy.
So what can it be?
Let’s find out .

I'm talking with Steve Falcioni from www.ecoorganicgarden.com.au

Choose as large a pot/container as you can accommodate in the spot where you want to achieve some privacy.

For my Magnolia 'Little Gem,' I have a 60cm terracotta round pot.

The disadvantage with round terracotta or ceramic pots, is that they can be bowled over in strong winds.

Mine has a large crack down one side having been blown to the ground numerous times during strong winds.

Magnolia Little Gem surround by orchids.
Cracked terracotta pot after being knocked over in strong winds.

There is of course the problem of replacing the soil which over a few years, will slump.

Rejuvenating Your Large Potted Plant

• TIP: employ help to push the container gently to the side then ease out the tree or large shrub.
• Use this opportunity to give the plant a root prune, about 10% all over.
• Replace any loose soil with good quality potting mix and only a couple of handfuls of compost, whether homemade or store bought.

If you really want a sure fire winner, then choose Murraya paniculata or commonly called Murraya, for your screening option.
Yes, I know it’s pretty common, but that’s a good choice if you’re prone to forgetting to prune it.
A lesser known and somewhat handsome plant that Steve mentioned is Radermachera “Summer Scent.”
Originating from Southern China, Summerscent has lush, glossy, compact foliage.
Best of all this plant has clusters of white to pale pink scented flowers that flower profusely throughout the warmer months.
A perfect plant for hedging or screens as it responds well to pruning and adds a tropical feel to the garden.
Summerscent grows well in full sun and shade as well as indoors if kept in a well lit position.

Savory, The Herb of Love

Winter savory (Satureja montana) is a perennial herb in the mint family (Lamiaceae,) and it’s native to warm temperate regions of southern Europe

• How many times have you heard the phrase "a savory stew?"

Savory is used in herb combinations, such as Herbes de Provence, a French combination of herbs used for seasoning.

• Savory is an annual or perennial herb, Satureja hortenis, for Summer Savory, or Satureja montana being for Winter Savory.

Winter savory is now little used in Australia, but for hundreds of years both winter and summer savory have been grown and used.

• Both have strong spicy flavour.

What do they look like?

They have dark-green, narrow leaves for winter savory and light green narrow leaves for summer savory.

The savories  can be used fresh or  dried and crushed.

History of Savory Herbs

The history of savory goes back about 2000 years and it’s one of the oldest culinary herbs.

 Here’s a surprising fact, the genus or first part of the latin name Satureja is derived from the word satyr, the half-man, half-goat creature in mythology who owned the savories.

It has been associated with love potions for centuries.

Romans used savory as a medicinal and culinary herb long before they discovered pepper.

In medicine they used it for bee stings, and as an aphrodisiac.

When the Romans brought savory to England, it was used there as an herb for chicken stuffing instead of a medicinal herb.

Winter Savory herb

• I have an English friend who says she grew this herb back in England and used it often in her cooking, especially with chicken.

As previously mentioned there are two distinct varieties of savory - summer and winter.

Summer savory is most often used for healing.

Summer savory is said to increase sex drive, while winter savory decreases it.

Make sure you get your savories right!

Medicinal Uses of Savory Herb

• The active ingredients of savory are carvacrol, p-cymene and tannins.It’s an astringent and mild antiseptic.
• A tea made from summer savory is said to control a mild sore throat.
• Rubbing a sprig of savory on an insect bite will bring instant relief.

What does Summer Savory like?

Summer Savory: Satureja hortensis

Well, it’s no different than growing Thyme, it likes full sun with well-draining soil.

Savory prefers to be planted in soil that's slightly alkaline.

Give it a side-dressing of compost or worm castings whenever possible. 

• Summer savory is bushy and low-growing so it makes an excellent edging plant for a kitchen garden, herb bed, or vegetable garden.
• Summer savory likes regular water. I have some growing in a strawberry pot so that it cascades out of one of the holes. It seems to like that spot better than the strawberries. As far as the soil in my container goes, well it’s just potting mix with soil wetter crystals added to it. So you see it's well-suited to container gardening, as well.
• If you know of someone with this plant, now’s the time to take soft-stem cuttings of about 2-3 cm long and put them in some seed raising or propagating mix. You probably don’t even need to cover it, because, just like the herb Thyme, it strikes very easily.
• Savory flowers in mid-January with white or pale pink 5mm flowers grouped in terminal spikes.
• You can begin to take the leaves from your savory plant as soon as it reaches 13cm or about 6 inches in height.
• Keeping the plant pruned means you’ll always have some.

 My plant dies down a bit in winter, but always regrows, so that’s a good reason to get some summer savory for your herb garden.

Tips For The Chef

• Summer savory, Satureja hortensis, is a nice herb to use when you are cutting back on salt-it's flavour is mild, a little bit similar to thyme, but with it's own unique flavour.

To me, it has a slightly peppery flavour, but a piney fragrance when you crush it in your hand.

• You can mince summer savory and combine with bread crumbs for coating fish or vegetables such as squash before sauteeing. Use it in potato dishes, tomato sauces, meatballs or vegetable juices. It's also great in egg dishes such as omelets and frittatas.

Savory is popular in teas, herbed butters, and flavoured vinegars. It complements beef soup and stews, chicken soup, eggs, green beans, peas, rutabagas, asparagus, onions, cabbage, and lentils.

Use savory when cooking liver, fish and game.

• Mince fresh summer savory leaves and combine with garlic, bay and lemon for a good marinade for fish.
• Savory blends well with other herbs such as basil, bay leaf, marjoram, thyme and rosemary. Chefs and cooks say that the taste of savory brings all these herbs together in a unique taste that makes savory an Amalgamating herb.

Why is it good for you?

Savory herb is an excellent source of minerals and vitamins -.

Its leaves and tender shoots are one of the richest sources of potassium, iron, calcium, magnesium, manganese, zinc and selenium.

This herb also has dietary fibre. Who would believe?

Potassium is an important component of cell and body fluids that helps controlling heart rate and blood pressure.

Tree Assessment and Grow Florence Fennel

DESIGN ELEMENTS 

Assessing Trees for Failure ( following on from blog on "Why Trees Fail"

 https://realworldgardener.blogspot.com/2020/04/why-trees-fail-and-celery.html

Trees are so beneficial in a garden that I can’t imagine having a garden without them.
For me they provide, an element of height, but often the ones I choose have flowers with sumptuous scent, and in summer, they provide much needed shade.

Arbutus unedo: Strawberry Tree photo: M Cannon

But how to prevent them from failing is the question in this week’s segment.
Let’s find out .
I'm talking with Glenice Buck, consulting arborist and landscape designer  www.glenicebuckdesigns.com.au

Trees fall from time to time and believe it or not, sometimes it’s not predictable, and sometimes it is.
Glenice says "it's totally impossible to predict if and when a tree will fail"

 BUT you can seek professional advice from a consulting arborist to relieve any worry that you have about that particular tree.

Champion tree in Stowe, England.

• The consulting arborist can make recommendation as to how to mitigate and potential problems.

Remember, a tree expert will cut out limbs correctly if they need cutting so the tree will be less likely to get insect attack or decay forming.
Consideration is given to remaining trees, if one needs to be taken out because it exposes them to more natural elements such as wind and changes in hydrology of the soil.

• Trees will overtime adapt if they lose a surrounding buffer.

A qualified arborist will use methods as outlined by QTRA and TRAQ are methods of tree risk assessment.

QTRA-Quantitive Tree Risk Assessment

TRAQ-Tree Risk Assessment Qualification.

From the www.treenet.org site

"The terms ‘hazard’ and ‘risk are not interchangeable.... A tree-failure hazard is present when a tree has potential to cause harm to people or property.  ‘Risk’ is the probability of something adverse happening; the likelihood that the hazard will cause harm.

Assessment of tree-failure hazards requires consideration of the mechanical integrity of the tree and the likelihood that the tree or part of it will fail within a given period."

Florence Fennel Foeniculum vulgare dulce and var. azoricum

Did I really mean Florence Fennel?

You might think that I’m trying to get you to grow that roadside weed that is found all over Australia.

No, I’m talking about the culinary fennel.

That other fennel was probably the Fennel  mentioned in the seed  inventory list brought out to Australia by the First Fleet in 1788.

• Fennel is a member of the Apiaceae family, which include parsley, caraway, dill, cumin, anise and carrot.

Fennel History

Did you know that in Ancient Greece fennel juice was used as an effective cure for poor eyesight, night blindness and cataract?

In medieval Europe, fennel and St John's wort were used together to ward off evil.

The real fennel (Florence fennel Foeniculum vulgare Azoricum Group;) is a cultivar group with a sort of bulb at the base that you can use in cooking, salads and stir fries.

Also the real fennel or Florence Fennel has a much milder anise-like flavour, than wild Fennel and is more aromatic and sweeter.

• Where  and When to grow it?

This plant is best in hot, dry climates but will grow in practically all climates of Australia.

•  Knowing when to sow the seeds is the key.
• Timing is crucial: if sown too early, cold can cause bolting; if sown too late, plants won't fatten up before the winter.
• Now is ideal, when the temperature is stable, day length is consistent and there's at least 16 weeks for bulbs to develop.

Zones in Australia

In sub-tropical areas, you can plant or sow seeds from March until May.

Temperate zones, from February until May. 

Cool temperate zones, you have from February until about mid- March.

Cold or mountain districts, it was February then not again until November/December unless you have a greenhouse.

Arid areas you have March and April and again in July.

• Should you have a soil thermometer, Fennel is best planted at soil temperatures between 10°C and 25°C  and as a general rule of thumb, soil temperatures are around a few degrees cooler than the current air temperature.

What is Florence Fennel Really?

Florence Fennel is a perennial that’s rather stocky and really only grows to about 60cm/

It resents disturbance and responds to any shock by bolting: so you’ll only get feathery fronds and flowers, but no swollen stems.

• Because the bulb grows only partially below ground, and mostly above ground it suits those districts with heavy soils. Otherwise, you can grow it in a pot-by itself.
  

Florence Fennel isn’t too fussy with soils as long as the veggie bed, or garden bed is well drained as has compost or decayed animal manure dug in, In cool temperate districts cut back the plant to about 10cm above the ground as winter draws nearer.

Planting/Sowing Seeds

When planting your Florence Fennel seeds –sow them about  5mm deep, and unless you’ve got a lot of space, you don’t need more than 2 or 3 because they need spacing of about 30cm.

TIP:

Never let the soil dry out because water is needed for germination, steady growth and swelling.

If roots become visible or plants seem unsteady, earth them up to stabilise them.

This will help make bulbs white and tender and, later, exclude frost.

How to Make The Base Stay White?

• After about 6 weeks you can hill out the soil around the emerging bulb so that, like Celery, the base stays white and is more tender than if you allow the sunlight to turn it green.Hilling up is just mounding soil or mulch around the base of the plant.
• You can make sleeves out of newspapers or use bottomless milk cartons to keep the hilled soil from getting into the leaves of the Fennel plant.

When Are They Ready?

Plants take several months to mature that’s 3-4 months after sowing.

• When they look big enough to eat use a garden fork to loosen the roots and cut the bulb off about 2.5cm above the ground.

This way you’ll get more feathery shoots that can be used as celery/dill-flavoured seasoning in the kitchen.

 The bulb is best sweet, ripe and fresh (try it raw in salads) but it will also keep for several weeks in a cool, dry place.

You can get root cuttings from plants that have been lifted during spring, so any if you attend a garden club, ask if any members have this plant.

There are plenty of seed suppliers in Australia that have Florence Fennel Seeds.

Why is it good for you?

The fennel bulb is also an excellent source of Vitamin C

Did you know that if you don’t get enough Vitamin C that’s linked to the increase in the incidence of rheumatoid arthritis and osteoarthritis?

Fennel also has folate (Vitamin B), fibre and potassium.

One cup of fennel has 10.8 per cent of the daily fibre intake, 5.9 per cent of the daily folate and 10.3 per cent of the daily potassium.

 An advantage of growing Florence fennel are that it attracts parasitic wasps and very small Praying Mantises.

It’s free of pests and it looks great and the Fennel bulb is delicious baked, too. Why not try it grated raw in a salad or baked in lasagne.. Definitely worth a try

Create A Bird Friendly Garden and Crop Rotation

DESIGN ELEMENTS

Building A Bird Friendly Garden

Wildlife in Australia has taken a massive hit with bushfires, then torrential rain that in some cases resulted in flooding.
Are you wondering where have all the birds gone in your garden ?

Or perhaps you have some of the more aggressive birds like Indian Mynah or Currawongs and want to know how to attract those smaller birds.

How can you help the birdlife in your garden?

Superb Fairy Wren

Perhaps start by thinking about creating an oasis, but there’s some essential steps that need to be observed first.
Let’s find out .
I'm talking with Glenice Buck, consulting arborist and landscape designer www.glenicebuckdesigns.com.au

If you provide your birds in your local area with a source of food, shelter and water, and that should help with not only supporting them, but letting you enjoy more of their presence. 

• Glenice points out that you need to plant in layers.
• This includes the canopy layer or larger trees, the shrub layer, then groundcovers and finally the leaf litter layer.

You may have noticed when you are walking in your district, where the smaller birds congregate.

This will give you some idea of the kind of habitat that they prefer.

You don't necessarily have to plant the same as in the bushland are nature reserves, because some might be weeds.

Grevillea Scarlet Sprite

For example, fairy wrens love to dart in and out of lantana bushes that are growing along a path under the Gladesville bridge in Sydney.

Instead, plant the type of style of bushes that these birds prefer; a shrub with dense foliage to the ground, such as Grevillea 'Scarlet Sprite,' or "Firesprite.' There's also a range of Callistemons or bottlebrushes that attract a variety including fairy wrens.

• Think about plants that flower at different times of the year so that you've got a food source all year round in your garden.

Crop Rotation 101

I thought I’d better address the whole crop rotation thing because of an email I received.

It was from a gardener in Auckland who had problems with his corn.

Some of the problems were caused by his planting the same crop twice in a row.

He was totally unaware that this can be a real problem.

• With his corn, the second crop was stunted and tasselled early. He was wondering why?
• I had told him that, early corn tasseling usually results when plants are stressed.
• Corn that is exposed to cold temperatures early in the growing season may develop tassels too early.
• On the flip side, corn tassels too soon, can occur if it is stressed by drought, nutrient deficiencies or hot and dry conditions.
• Perhaps one of those reasons outlined may be the cause?
• He had added compost before planting the second lot but the compost wouldn’t have been enough.
• He would have needed to add a barrow load of decomposed manures, but then waited for a few weeks for that to break down in the soil so that it was available to plants.

It’s not ideal to plant the same crop twice in the same garden bed. 

Crop rotation does a couple of things. The purpose is to prevent a build up of pathogens in the soil which can infect and re-infect particular families of plants.

Another purpose is that plants absorb different quantities of soil nutrients, and repeated plantings will quickly deplete the soil.

Crop rotation allows for more balanced soil fertility and microbial balance.

• Here’s the outline of a basic 4 bed rotation system that I call Crop Rotation 101.

I will outline one of the beds.Let’s call it bed 1.

Say you start with Legumes which includes beans, peas, broadbeans.

You will have to adjust to the seasons yourself.

• Because winter is approaching the legume could possible be planted with peas or broadbeans in most areas.

If you were starting this rotation in spring/summer, then beans and okra would be sown here.

When that crop has finished, in that same bed, the alliums will follow.

• So alliums follow legumes.
• You can choose from onions, shallots, leeks and Garlic.

Following on from Alliums, you would go to root and fruiting crops.

• Root  and fruiting crops follow alliums or the onion family.

There’s quite a choice here, but in winter it might be potatoes, parsnips, carrots, beetroot and in spring or summer, sweet corn, tomatoes and capsicums.

Still in bed 1. There’s one more rotation before you can plant the legumes again.

The last thing to go in this bed is from the brassicas.

• Brassicas are then following root and fruiting crops.

Hopefully you know the brassica family really well.

They include in autumn/winter cabbages, English spinach, broccoli, turnips and parsnips, depending on your district of course.

• In spring/summer you may want to plant silverbeet, radishes, mustard greens and pack choi.

If you don’t have enough room for 4 beds, even 4 little vegetable beds, then you need to just stick to one crop.

You’re probably wondering what do I plant in the other beds?

Stay with me, because it can seem complicated.

Remember I started off with legumes in bed 1.

• At the same time, and in bed 2, I would be on to Brassicas.
• Also at the same time and bed 3, I would plant out something from the root and fruiting crops.
• And, at the same time, I would plant something from the onion or allium family in bed 4.

So if you were in a warm temperate area right now, this is what you could have in your veggie garden, assuming the beds aren’t that big.

Bed 1, climbing peas-yes they are legumes

Bed 2 sprouting broccoli, from the brassica family

Bed 3 carrots, root crops of course

Bed 4 garlic and leeks. From the onion family or alliums.

That wasn’t so hard was it?

Black Bean Tree in Plant of the Week

PLANT OF THE WEEK

Common Name: Black Bean Tree: 

Scientific name: Castanospermum australe
Family: Fabaceae

Native distribution: east coast of Australia in Queensland and New South Wales, and to the Pacific islands of Vanuatu, New Caledonia

Over the last few weeks in this segment, we’ve been talking about big, big trees, and today’s offering is no exception, but perhaps not as big as the Kauri Pine.
This tree, although very range with amazing huge boat like seed pods, is in the same family as peas, beans and broadbeans.

Castanospermum australe

The Black Bean tree makes an interesting pot specimen. 

Lovely red and yellow pea like flowers, typical of the legume family.
I'm talking with Adrian O”Malley, horticulturist and native plant expert.
So let’s find out more.

• Black bean tree is an attractive Australian rainforest tree with dark glossy leaves and masses of yellow and red flowers during summer. 
• Flowers attract lorikeets and other nectar feeders.

Sometimes used as street trees as long as they’re not under power lines. 

DO NOT plant in the garden, because it has invasive roots.
Certainly bird attracting when in flower and has a spreading canopy when it matures.

If you want to grow it from the large bean like seed, sow the seed so that half of it is inserted into the seed raising mix.

Attractive pea like flowers of Castanospermum australe

Sometimes sold as a novelty plant with 6-10 seeds in a small pot, sort of like a bonsai plant but with many stems.
Unless you have a large garden, we recommend that you can plant this one successfully in a pot for many years.

• The beans of Castanospermum austral or black bean tree or toxic to everyone. 

Sydney Botanic gardens have a couple of these trees and various suburbs such as Hunters Hill, have the occasional Black Bean tree as a street tree.

Planting to Deter Mosquitos

The warmer months of the year can become the bane of a gardeners life, or in fact anyone who likes the outdoors, if hordes of insects invade your personal space. 

I’m talking mainly mosquitos,  because they bite, but flies can just be just as annoying if your relaxing in your garden, or having friends and family over for a bbq.
So what can we do to deter them?

Pelargonium graveolens: scented geranium

I'm talking with Glenice Buck, consulting arborist and landscape designer www.glenicebuckdesigns.com.au
Let’s find out more.

There are plenty of foliage plants that have a particular fragrance which deter insects, but you have to plant a lot of them, not just one or two.

Brushing the foliage releases the scents, so plant them close to where you entertain.

Most successful plants are what you think of as herbs: mint, basil, lemon scented verbena, sage.

Catnip, lavenders, scented geraniums, bee balm (Monarda spp.)
The biggest tip is not to expect the lone rosemary shrub or Tea tree Mozzie Blocker (Leptospermum liversidgei) , to do that heavy lifting in terms of fragrance.

Mozzie Blocker tea tree.

Plant them right around the area where you sit and enjoy your garden so they act as a buffer zone between you and the insects.

Chicory! Cichorium intybus

Have you ever eaten chicory?

• What do you do with it other than give it to your chooks? Apparently the leaf chicory is very good for them?

Did you know that there’s actually two types of chicory, both of which are considered a vegetable?

There’s the leafy type and the one where the tap root is used more.

But let’s begin with some interesting facts.

• Chicory comes from the daisy or Asteraceae family, and like dandelion, chicory has been grown since ancient times as a pot herb.
• A pot herb is one you put in a pot along with your meats and vegetables and cook together for a while-usually a long while.

Chicory is most likely native to the Mediterranean region and it’s an interesting plant because it’s been used in coffee substitutes and additives where the roots were baked and ground.

You probably didn’t realise that Chicory used as a coffee substitute during the Great Depression in the 1930s and during World War II in Continental Europe.

• Do you realise that if you’ve ever drunk a coffee substitute, like Caro, then you’ve drunk roasted chicory root?

Some beer brewers even use roasted chicory to add flavour to stouts.Some other beer brewers have added it to strong blond Belgian-style ales, to add flavour to the hops, making a "witlofbier", from the Dutch name for the plant.

• So how come chicory can be used as a coffee substitute?

Chicory contains two polysaccharide, inulin and fructose.

When these are roasted, inulin is converted to something called oxymethylfurfurol, OXY-METH-OL-FUR-FUR-OL and this gives off that coffee-like aroma.

• Did you know that the first person to grow and process chicory in Australasia was Edwin William Trent (1839 - 1883)?

Eddy or Edwin, operated a steam coffee mill in Nelson in New Zealand, and later moved to Christchurch where he established the first steam coffee mill in Australasia in1863.

Did you also know that Chicory, or Cichorium intybus, was grown as a crop on Phillip Island for nearly 100 years from the 1870s?

• If you’ve visited Philip Island you’ll see some unusual small brick towers dotted about the island.These are chicory kilns, once used in drying chicory dock – a parsnip-like underground root of the Chicory plant that was grown widely in Phillip Island’s rich volcanic soil.

Are you thinking, I’m not going to bother drying and roasting the chicory root, what on earth do I need to grow this ahem, vegetable?

Here’s the reason: Chicory is actually a nutritious food.

The leaves of the chicory plant can be eaten in salads to add flavour and crunch.

They can also be lightly roasted in olive oil.

You can buy seeds of Chicory “Red Dandelion: this plant has red stems with deeply cut frilly deep green leaves.

As a microgreen or ‘baby leaf’ this variety adds great flavour to salads and it’s a colourful addition to any mesclun mix.

If you get the red variety, it’s one of the few red leafy vegetables that keeps the crimson colour when cooked.

Chicory ‘Red Palla Rossa’ is a small heading chicory, 8 - 10 cm across .

The bright red, very tight heads have prominent white midribs. It has a slightly bitter, tart taste.

As a ‘baby leaf’ they add great flavour to salads.

There’s also the coffee chicory plant or Chicory Coffee 'Magdeburg' which also has the same botanical name of Cichorium intybus.

So What Is Chicory Plant?

This chicory is also a frost hardy plant but with a long taproot topped by a whorl of oblong, broadly toothed, milky-sapped leaves.

The flowers are on top of 1 ½ metre tall, zig-zagging flowering stems with a few sparsely placed leaves and lots of sky-blue to purple flowers.

Flowering is mostly in summer and the 50 cent-sized flowers open at the beginning of the day but close as the heat becomes intense.

Chicory plants flower for several months and the flower looks quite a lot like a purply-blue dandelion flower.

Like dandelion, the seeds are spread by wind.

Also, like dandelion, the leaves are concentrated in a whorl, just above the soil surface.

If you really wanted to you could dry and roast the roots, then grind them for a coffee substitute.

The leaves and young roots can also be cooked as vegetables.

The roots can grow up to 30 cm long and weigh as much as 1 kg.

The one I have in my garden has been there for over a year so I’m guessing that it’s going to have a heavy large underground root.

Chicory is a hardy vegetable and frost tolerant but does wilt a bit on hot days.

It’s a useful cool season crop to add interest to winter salads.

• When To Grow?

To grow the leafy Chicory, for sub-tropical areas, April to June is the time to sow, in Temperate areas March until May, for Arid areas June to August, and Cool temperate districts, sow late summer to mid-autumn.

• In all cases sow the seeds directly where they are to grow.

So to grow Chicory you need a well- drained, deep soil.

Chicory will also grow on heavier soils as long as they’re not likely to get waterlogged for extended periods.

• Are you wondering if Chicory is just as weedy as Dandelions?

It’s unlikely to become a weed since plants tend be short lived.

If you’re growing the coffee chicory, the fleshy taproot of the first year’s growth is dug up in winter, dried, ground and roasted.

(Roast the roots on low heat (around 250 C) until crisp, then grind with a little roasted barley (around 400F or so) for a wholesome coffee substitute.

It contains no caffeine and just adds bulk to coffee, although its bitter flavour can give bland coffee a bit more "bite".)

• Here’s an interesting fact: Coffee is readily available now in all types of strengths but until the 1960s, before instant coffee was invented, coffee and chicory essence was a popular alternative to using roasted coffee beans.
• Do you remember that thick black liquid with a very distinctive attractive aroma and sold in squarish bottles with a blue label? It was often drunk with sweetened condensed milk.

Why is Chicory, good for you?

One of the major functions of chicory is to increase the body’s ability to absorb calcium.

The leafy greens of chicory are a good source of calcium and vitamin K;

They also contain folate and like other green vegetables chicory contains good  amounts of potassium.

Chicory is also good for the digestion, and the circulatory system.

From an agricultural point of view, Chicory is used as a short and medium term forage, and is an alternative to lucerne in areas where soils may be too acid for lucerne. Tolerates a pH down to 4.2

3D African Daisies and Others

PLANT OF THE WEEK

African Daisy: Osteospermum sp

The daisy plant family (Asteraceae) is one of the biggest in the world.
In fact it includes 32,000 species and 1,900 genera and 13 sub-families.
The seeds of the osteospermums are quite hard. 

All are classified as sub-shrubs with green leaves and 90% of Osteospermums that you see for sale are from the same species.

Botanical Bite:

The daisy flower contains outer sterile ray florets (what look like petals) and the inner part of the daisy, or the 'eye' contains hundreds of tube like flowers and are referred to as disc florets.

Osteospermum sp.

We all know what daisy flowers look like, but what are modern day breeders doing with the colours and shapes?

Is the centre of Osteospermums always a blue eye?
So let’s find out .
I'm talking with Jeremy Critchley, horticulturist and owner of the Green Gallery nursery.

• What about those daisies that have no centre?

With the fully double flowers, the disc florets that contain the sexual organs, have been genetically replaced  with petals making the flower fully double. These varieties cannot close at night, unlike the singles. 

• Most Osteospermum's have a blue 'eye.' Any other colour?

There are two cultivars that Jeremy grows with different coloured centres:

Voltage Yellow has a yellow centre.

Osteospermum 3

White Lightning, creamy white with a cream white centre.

The doubles cannot close at night because of the amount of petals in the centre.

There's a range called the 3D's which include yellows, reds, oranges and many shades of pink.

3D's have names like Violet  Berry, Banana Shake-usually with two tone colours.Jeremy mentioned that he used to grow 80 different colours of African daisies. Can you think of 80 different colours?

• Jeremy'sTop Tip:

Osteo's love food, or fertiliser. The more food, the more flowers.

• Can you think of 80 different colours?Nope? 

Well, Jeremy now only grows 30 different colours and I bet you would be hard pressed to think of more than 7.

• Funnily enough the classic white petals with blue centres are still the best sellers.

Why Trees Fail/Fall?

When a large, mature falls in your garden, it can be very disheartening, especially if it’s a special or favourite tree.

You may be left wondering what happened to cause it to fail after 20 or 30 years.
Sometimes it’s obvious why a tree may fall in your garden, but what are the underlying factors?
I'm talking with Glenice Buck, consulting arborist and landscape designer.

Let’s find out .

There are many reasons why trees fail or fall.

• Trees need to be growing in well drained soil. 
• If the soil holds onto too much moisture, this results in no oxygen in the soil, leading to tree roots rotting, making the tree unstable.

Trees will also fail or fall over in extreme weather events if they're susceptible.

Heavy rain inundation together with strong winds undermine the soil that the tree is growing in, particularly if the soil is shallow.

Glenice talks about the force of the wind, where the canopy of the tree acts like a lever, causing it to topple.

Sometimes the tree can be rescued by giving it a hard prune and winching it up, but that is the exception rather than the rule.

• Trees not planted correctly is another factor.
• The planting hole needs to be wide enough so there there is enough room for the roots to spread . The hole should have more of vase shape, and loosen the soil so there is no soil 'glazing.'
• Don't plant the tree too low in the ground.
• If the tree is planted into a tight narrow space, not giving it enough room for the roots to develop to support the canopy.

If you want to know more or if you have any questions about why trees, fail, next week’s episode is about assessing trees for failure with Glenice.

VEGETABLE HEROES

Celery or Apium graveolens

• Fun Fact: Did you know that at first, it wasn’t meant for consumption, but instead, celery was used for medicinal purposes, as a flavouring herb, and sometimes fed to horses.
• Celery or Apium graveolens is in the same family as carrots; Apiaceae

If you’ve ever let your celery self seed you would’ve noticed that the leaves become a bit feather and the flowers look like those of carrots.

Flowers of Celery

History of Celery

Did you know that celery leaves and inflorescences or flowers were part of the garlands found in the tomb of pharaoh Tutankhamun (died 1323 BC),?

Another interesting bit of trivia is the romans used celery seed in pills for relieving pain (as described by Aulus Cornelius Celsus) around 30 AD.

The Greeks believed celery to be a holy plant and so it's not surprising they wore necklaces of it at their version of Olympic Games.

For the ancients there was not much difference between celery and parsley. In fact the name for parsley actually means rock-celery.

• Have you tried growing Celery and found it to be too much work?

Celery has had that reputation of being a difficult crop to grow, mainly because traditional varieties need a lot of work and attention - they have to be planted in deep trenches and require layers of soil added regularly to blanch the green stems. 

Otherwise the celery tastes too strong and bitter.

I know of one gardener who uses sheets of corrugated iron against his celery patch to blanch them.

Must love his celery!

• Did you know there are, self-blanching varieties that don't need earthing up to produce tender white stems?

When to Grow

In sub-tropical districts you can plant them from April until November, Tropical districts only from March until July.

In temperate zones-August until December.

For Arid areas-May until August.

Finally cool temperate districts-I’m afraid you’ll have to wait until September, then you’ll have until the end of December

What Celery likes:

• Celery prefers moisture, well-drained soil in a sunny spot. 
• A short row can be squeezed into a garden, raised bed or you could even try dotting the odd plant into a border. If you have a tiny garden it's possible to grow celery in very deep, long tomato style pots.

Celery is a biennial plant (which means that they flower, fruit, then die in the second year) but are generally grown as an annual.

• Celery prefers warm days and cool nights and grows best in a clay to sandy soil with plenty of moisture.

Soil preparation

Dig the soil (in the spring before planting), removing big stones, weeds and incorporating plenty of garden compost or well-rotted manure.

A week or so before planting, rake a general purpose organic fertiliser (90g per square metre) into the surface layer of the bed.

How to sow seeds

Celery seedlings

• If you have time, plants can be started off by sowing seeds. The seeds take 1-2 weeks to germinate.
• Celery seed is tiny, so take a pinch and lightly sow across the surface of the soil. Watering from the top is likely to disturb the seed, so fill a bowl with water and put in the pot. It can be removed once the water has been drawn to the surface.
• Finish by covering with a thin layer of vermiculite and putting in a heated propagator on a windowsill or in a greenhouse. Water daily to ensure the compost doesn't dry out.
• Take the seedlings out of the propagator when they've germinated. 
• They're ready to be given pots of their own when the first proper leaves have formed.  That means at least 4 leaves.
• Plants will be ready to go outside about five weeks later, when they're 8cm tall.

For perfect plants with lots of well-branched sticks, plant celery seedlings about 27cm  or a ruler width apart making sure that the crown of the plant is at ground level.

Plants will grow better if they're arranged in a grid pattern, rather than planted in long rows.

TIP: The secret to fresh crisp stalks is plenty of manure and water, don't let the soil dry out as it has shallow roots.

Keep celery well-watered and the area around them free from weeds.

Plants can be given a boost by feeding with a balanced liquid fertiliser about a month after planting.

Celery Leaves

Harvesting

Celery will be ready for picking in about 3 ½ to5 months, depending on the variety you grow.

When picking your celery just lift plants using a hand fork, taking care not to damage neighbouring plants.

• One of the main advantages of growing your own is that you can individually pick the stems one by one rather than taking out the whole bunch.

TIP: For best flavour and longer storage, water celery plants the day before harvest.

Best Varieties

A variety called Celery Dorata D' Asti Apium graveolens var. Dulce is available from a one www.diggers.com.au and Stringless American that is normal to use unblanched.

I'll be getting my seeds from them rather than buying celery seedlings and having to try and blanch (unsuccessfully) then ending up with bitter tasting celery.

The Dorata  variety is easier to grow than other varieties, remaining crisp and juicy without the need for blanching. The lime-green stems can be snapped off from summer through to autumn and winter.

Although plants can be grown from seed sown in early spring, it's far easier to buy ready-grown seedlings, which can be planted out in August onwards, depending on what zone in Australia you live..

A third NSW seed company has Golden self Blanching variety, which by all accounts, tastes the best.

Why is it good for you?

On top of the above celery health benefits, celery is known to be a negative calories vegetable.

Which means that the body uses more energy to digest than absorb calories from it!

Add the fact that Celery's high water content and fibrous nature mean that it is great for those who like to snack without gaining weight

A medium stalk of celery contains around 10 calories, 2g of carbohydrates, 1g of protein, zero fats and cholesterol!

Celery leaves can also be eaten or used in soups or used to make celery
