Expert Hedging, Rosella Tea and Tropical Flowers

What’s on the show today?

Expert hedging tips in Tool Time, sharp and tart, sweetness you can grow in Vegetable Heroes. Part 2 of gardening in tight spaces in Design Elements, and flowers that hate the cool-room in the Talking Flowers segment with Mercedes.

TOOL TIME

Expert Hedging
Chances are you have a hedge in your garden, maybe to hide the back fence or just for show.
Hedges come in sizes and shapes and even vary in the colour of their leaves.

Chosen carefully hedges don’t need that much maintenance in the form of pruning or clipping or even disease control.
Perhaps you’ve let it go over the years, and now it’s that bit too high to manage easily making you dread having to tackle it.
Let’s find out how to get the hedge back into shape.
I'm talking with Tony Mattson General Manager of www.cutabovetools.com.au

Today’s episode was all about bringing that 3-4 metre high hedge back to a more manageable height, starting with the top first and only lightly pruning the front.
Tony's expert hedger, Simon was tackling a lilly pilly, Acmena smithii minor "Goodbye Neighbour," and Murraya.
Plumbago and Muehlenbeckia hedge
Recommendation:Simon's recommendation was to hard prune hedges only in March-April, and August-September.
Each time you
You will need to use long handled (1.2m shears) as well as normal sized hedge shears.
Also, a pair of secateurs to cuts some of the thicker stems that are too hard for the hedge shears.
BIG TIP: cut or trim the hedge back, do it in stages, that is , a bit deeper each prune, otherwise you risk losing the hedge or getting a lot of dieback. 
You might start off with cutting the top back 1/2 metre in the first stage, wait a month, then come back and cut a bit deeper .
At this point, only lightly prune the front of the hedge 5-8 cm leaving lots of new growth.

VEGETABLE HEROES

Rosella (or sometimes known as Roselle plant.)
Botanically-Hibiscus sabdariffa.
Being a hibiscus it belongs to the Malvaceae family of plants that mostly come from tropical Africa.
Did you know that in 1892, there were 2 factories producing rosella jam in Queensland, Australia, and they were even exporting big quantities to Europe? Didn’t last though finishing up around the early 1900’s
Where does it grow in Australia?
Rosella grows in a wide variety of climates because it’s very adaptable, possibly weedy even.
It grows especially well in dry climates right through to tropical climates.
The only drawback is that the growing season is 5 months, so you need to start this weekend.
Why grow Rosella plants?
Well the Rosella plant looks nice with its green leaves that have red stems and red veins and the flowers are deep pink hibiscus like; but the fleshy red calyx-about the size of a shot glass is the part underneath the flower.
Rosella calyx
This calyx is excellent in making jams, sauces, cordials, in fact it’s the main ingredient in a herbal tea called Red Zinger.
Botanical Bite:If you were wondering what a calyx is (calyces-plural),  its just the collection of sepals behind the petals of a flower.
Sepals in most flowering plants are leafy and green, that make up the outer protective covering of a flower bud. Think of a rosebud as an example.
Germinating Rosella Seeds
Rosella seed is a little hard to find unless you look in seed saver networks, or organic growers, certainly you’ll find them at organic markets where there is a seed stand.
Nurseries will have seedlings in late spring early summer if they carry unusual plants.
Seeds remain viable for a good long time but soak the small hard triangular seeds in warm water to help speed up germination.

Don’t drown them, just a saucer of water overnight will do.
Rosellas need a very warm soil to germinate, preferably over 25°C.
In tropical areas, they sow the Rosella seed in early spring.
In the Northern Territory the seed is sown during the early wet season as Rosella is a long day-length plant and needs 12–12 ½ hours of daylight to flower.
In NSW areas and more southern areas of Australia this would be as late as October early November outside.
Some years the soil might take even longer to warm up.
So gardeners in cooler areas need to start seed indoors using a small bottom-heat unit, or the top of the water heater.
Cover the seed with 12mm of fine soil or seed raising mix.
Rosella plants begin to crop when they’re 3 months old.
I’ve read that 3-4 plants will give you enough fruit to make jam or tea, but I’m not sure how much jam and tea that might be, so you could trial it with just a couple of plants because they take a bit of room.
Where to Put It?
Too much for the veggie garden so go for the flower bed or flower pot.
Now it grows to 1 ½  metres so a big pot will be good.
There is more than one flush of seed pods, but the trick is to remove the first flush because the second is much bigger and better..

When to harvest?
You’ll know the Rosella bud is ready when it easily come away from the bush, usually 3 weeks after the flowers have finished when the pod is 2-3 cms across.
Keep them well watered but it must drain away reasonably quickly because
Tip: Rosella plants are prone to root rot
Roselle plants are weedy in the Northern Territory and Western Australia-but aren’t a problem anywhere else.
If you are going to go for growing this plant, here’s a tip:
When the fruits are about the size of a walnut, about 20 days after flowering, you need to separate the seeds from the inflated and ripened outer fleshy casings or the calyces- or fleshy part.
The best way to prepare Rosella fruit is firstly by washing it, then making an incision around the tough base of the calyx below the bracts to free and remove it with the seed capsule attached.
The calyces are then ready to be used in jams or teas or whatever.
 They may even be chopped and added to fruit salads.
Use an apple corer-from kitchen shops.
By the way the young shoots and leaves can be eaten raw or cooked as a vegetable.
To make Rosella tea-

The dried red calyx is used for tea and it is an important ingredient in the commercial Red Zinger, Hibiscus and Fruit teas.
The tea is very similar in flavour to rose hips and high in vitamin C.
To make it, strip off the red calyx (the fleshy cover surrounding the seed pod) and dry it in a solar drier or a slow oven until crisp.
Only two small pieces are needed per cup.
Try mixing it with dried lemongrass or lemon verbena and dried organic orange peel  for a wonderful herb tea that is also good chilled.
If you want to make Roselle jam or cordial, go to my website for the link to the recipes.
Why is it good for you?
Rosella hips contain a very good source of Vitamin C, and is rich in Calcium and Magnesium. vitamin A, and amino acids.
Also Rosella is rich in anthocyanins , essential minerals and vitamins.
Roselle is very low in Cholesterol and Sodium, and is a good source of Vitamin A, Vitamins B1 and B2, Niacin, Iron and Potassium.
Anthocyanins are water-soluble flavonoid pigments, which are responsible for the red, blue and purple colours in many fruits and vegetables.

DESIGN ELEMENTS
Gardening in Tight Spaces part 2:
Eco Pillows, grow baskets, and vertical gardens turned on their side.
https://greenwall.com.au



Tired of hearing about green walls because
a) you think they’re too expensive,

b) sounds too hard to maintain or

c) you’re just not into green walls.

So what else can you have that’s much cheaper, easier to put up and more of what you want?


I'm talking with Peter Nixon, garden designer and director of Paradisus garden design.



Let’s find out more.
https://greenwall.com.au If you want a more relaxed style of vertical planting then go for these vertical grow baskets.
In them you can put in plants with pendulous foliage such as:
  • rhipsalis, 
  • aeschynanthus, anything from the 
  • gesneriad family, such as
  • nematanthus, 
  • columnias, and gloxinia sylvatica or whatever you like really.
Nematanthus: Goldfish plant

TALKING FLOWERS

How to care for Tropical and Exotic flowers.
So, what does your florist do to keep their flowers in such fantastic shape?
For every florist, no matter where they are in the world, keeping flowers at just the right temperature is essential. 
Frangipani flowers photo M Cannon
That’s what makes their refrigerator(s) the most important piece of equipment. 
A small flower shop might have just one fridge in the back of the shop whereas larger florists will have larger, walk in fridges and their premises might resemble more of a warehouse design. 
Small flower shops usually place just a few bouquets on display in the front on the shop while the rest of their flowers are safely stored in temperatures ranging from 50 to 120 C.
This is what a commercial cut flower grower in FNQ recommends. 
Cut Flower Care
Chandelier Orchid photo: M Cannon
  • Never refrigerate tropical’ s they should NOT be stored below 13 degrees.
  • Tropical’ s like tempered conditions.
  • Keep Tropical’ s away from direct heating and air-conditioners units.
  • Drastic changes in temperature burns fresh cut flowers.
  • When handling exotic tropical flowers keep in mind that cold weather can affect them, keep your exotic tropical flowers in a relative warm area.
  • To get the best out of your Tropical flowers after you unpack them you can submerse them in a bath tub or a large bucket/bin for 20 mins with tempered water NOT ice cold tap water to re hydrate them from travelling.
  • Re-cut stems at least 2 to 4 cm with sharp secateurs.
  • Preservative is optional.
  • Replace water every day – these large flowers are thirsty.
  • Misting is recommended once or twice a day as they like high humidity.

Sweet Leaves, Nectar and Flowers

What’s on the show today?

A tiny honeyeater in Wildlife in Focus, sweetness you can grow in Vegetable Heroes. A new series starts in Design Elements, that’s gardening in tight spaces and less value for money cut flowers in the Talking Flowers segment with Mercedes.

WILDLIFE IN FOCUS

Eastern Spinebill
Did you think all honeyeaters were on the large side in Australia?
Well if you did, you’ll be surprised to learn that there’s a tiny honey eater weighing only 11 grams.
Not only that, the Eastern Spinebill is the only Australian honeyeater that will feed will flying.
So how can you spot them because they’re bound to be terribly shy?
Firstly get up at the crack of dawn, when most birds are out and about then listen to what Holly has to say about them.
Let’s find out more.
 I'm talking with Dr Holly Parsons from www.birdsinbackyards.net

America has the humming bird but Australia has the Eastern Spinebill which can hover will extracting nectar from flowers.
Not as spectacular as the hummingbirds, but pretty amazing all the same.

You can spot the eastern spinebill male has a grey black crown, white chest and throat with a rusty patch right in the middle, plus a beautifully curved beak to get the nectar from flowers, particularly tubular flowers.
Listen out for their call which as a few variations. Often though it includes a staccato like twittering.

If your garden is near bushland and you want to attract the eastern spinebill, then think about planting more of those tubular flowers like epacrids ( pictured below) and correas.
Epacris impressa var, grandiflora
Also smaller flowering grevilleas like Grevillea sericea and Grevillea speciosa.

VEGETABLE HEROES

Stevia rebaudiana
Native to Paraguay and other tropical areas of the Americas, the stevia plant (Stevia rebaudiana) has leaves packed with super-sweet compounds that keeps its sweetness even after the leaves have been dried.
Stevia is a member of the chrysanthemum family but did you know that Stevia leaves have been used to sweeten teas and other drinks throughout South America for centuries?
So why are Stevia leaves’ so sweet?
Because the leaves contain something called steviol glycosides.
Steviol glycosoides are high intensity natural sweeteners, 200-300 times sweeter than sugar.
In fact the leaves of the stevia plant contain not just one, but many different steviol glycosides and each one varies in sweetness and aftertaste.
So what does Stevia plant look like?

Stevia is a small perennial shrub with small pointed lime green leaves that do best in a rich, loamy soil — the same kind that most of your plants in the garden like.
It has little white flowers at the end of long stems.
Stevia is native to semi-humid, sub-tropical climates where temperatures typically range from -6°C to 43°C.
  • Although Stevia tolerates mild frost, heavy frosts will kill the roots of the plant.
  • Since the feeder roots tend to be quite near the surface add compost for extra nutrients if the soil in your area is sandy.
  • From all that, you could guess that Stevia is evergreen in temperate, sub-tropical and tropical climates, but in cold and arid districts, it’ll lose its leaves in Autumn.
  • By the way, I’ve grown my stevia plant in a pot for several years now without any problems and it’s survived several bouts of dry hot summers and lack of watering during spells with a house sitter.
  • But, it really isn’t drought tolerant like a succulent or a cactus and won’t tolerate long term neglect.
    Stevia flowers
  • During warm weather don’t forget to water it and if you’re going away for a few weeks put in a dripper system, otherwise you’ll lose your Stevia plant.

TIP:But don’t plant your Stevia in waterlogged soil and don’t overwater it.
 Adding a layer of compost or your favourite mulch around your stevia plant so that the shallow feeder roots won’t dry out.
 Stevia plants do best with fertilizers with a lower nitrogen content than the phosphorus or potassium content.
Which means the artificial fertiliser aren’t your best bet, but most organic fertilizers are because they release nitrogen slowly.
HINT: Stevia leaves have the most sweetness in autumn when temperatures are cooler and the days shorter.

Definitely the best time to pick those stevia leaves.
If your district is prone to frosts in Autumn, make sure you cover the Stevia plant for another few weeks’ growth and more sweetness.
How do you store Stevia leaves?
If you Stevia plant is big enough, the easiest technique is to cut the branches off with secateurs before stripping the leaves.
TIP:As an extra bonus, you might also want to clip off the stem tips and add them to your harvest, because they have as much stevio-side as do the leaves.
 If you live in a mostly frost-free climate, your plants will probably cope with winter outside, as long as you don’t cut the branches too short (leaving about 10cms of stem at the base during pruning).
These plants do last a few years in temperate and warmer climates.
In cool temperate districts, it might be a good idea to take cuttings that you’ll use for next year’s crop.
Cuttings need to be rooted before planting, using either commercial rooting hormones or a natural base like honey.
Stevia seed is apparently very tricky to germinate, and the cutting method is your best option.
 SO HOW DO YOU USE YOUR STEVIA LEAVES?
I should mention that the stevioside content is only 12% in the leaves you grow compared with the 80-90% that commercially extracted stevia has.
It’s still had a decent amount of sweetness all the same.
So you’ve picked the leaves now you need to dry them.
  • As with drying all herbs you can hang your bunch of leaves upside down in a warm dry place.
  • Otherwise, on a moderately warm day, your stevia crop can be quick dried in the full sun in about 12 hours. (Drying times longer than that will lower the stevioside content of the final product.)
  • If you have a home dehydrator use that instead.
  • Finally crush the leaves either by hand,  in a coffee grinder or mortar and pestle that you use for spices and herbs.
  • The dried leaves last indefinitely!
  • If you add two or three leaves added whole or powdered, that’s enough to sweeten a cup of tea or coffee.

HOT TIP: Another way is to make your own liquid stevia extract by adding a cup of warm water to 1/4 cup of fresh, finely-crushed stevia leaves. This mixture should set for 24 hours and then be refrigerated.
Why are they good for you?
 Stevia is a natural sweetener that has zero calories and isn't metabolised by the body.
Stevia isn’t suitable for everything in cooking but you can use it to sweeten drinks, fruits, salad dressings, stewed fruit, yogurt and most creamy desserts.
The processed Stevia that you buy in the shops has been stripped of all the natural goodness that Stevia contains, so it’s better to grow your own Stevia.

Gardening in Tight Spaces Part 1

Tillandsia capitata
Gardening in tight spaces seems to be a modern day occurrence with people living in smaller and smaller accommodation.

Today we’re tackling a tiny balcony situation high up on the 7th floor.

That may not be where you live, but there’ll be something that you can take from this.

Let’s find out.

I'm talking with Peter Nixon, garden designer and director of Paradisus garden design 


If you have a westerly aspect that’s under cover, go for anything in the Tillandsia family.

Peter suggests Tillandsia fasciculata hybrids and Tillandsia capitata hybrids.
And the suggestions were if you’re stuck with a tiny balcony, or even courtyard, then do use those vertical surfaces.
Those modular units can be a bit pricey, but there are alternatives if you’re prepared to do your own hand watering. If you have any questions about gardening in tight spaces or have a suggestion either for me or for Peter why not write in or email me at www.realworldgardener.com

TALKING FLOWERS

Shorter Lasting Flowers for the Vase:

True love may last forever, but flowers do not. Some flowers only last a day. But what a day!

Some flowers do alright in the garden, but not so good in the vase.
So which ones are they?

 Short vase life, anything less than 7 days.
Daylilies make the top of my list. Not true lilies because they belong in the Hemerocallis family.
Each flower only lasts 1 day like its name says but they come in all colours of the rainbow. In fact there used to be a daylily farm called Rainbow Ridge.
 Hibiscus flowers only last 1 day, but in temperate climates they flower for at least 6 months of the year. Longer in warmer climates.

The hardy hibiscus bush can produce up to a hundred flowers in a season.
Evening Primrose-flowers that open in the evening and close again the next morning. If it’s cloudy though, the flowers will stay open. They just don’t like opening for the sun.
Queen of the night.-member of the cactus family, you’ll have to stay up late to watch this one flower. Also known as night flowering cereus.
Desert plants and cacti can have gorgeous, sometimes also fragrant, flowers which last less than a day.
Bearded Iris-only flower for a few weeks then are gone until next season can also be cut for the vase. Will last 4-5 days..
Iceland Poppies have a short vase life of 4-5 days.
Cosmos also 4-5 days. Pick them when they’re not 100% open.

Cosmos
Things you need to do to keep the flowers longer in the vase.
Change the water every two or three days, making fresh stem cuts and adding more floral preserver. Never use tap water, only filtered water.
With roses, avoid fully opened blooms, but also pass on stems with tight buds. Roses harvested too early will not last as long as those that have been cut later.


And remember, true love may last forever, but flowers do not. “It’s OK for flowers to die,” Miller said.

Tickle Your Taste Buds and Value Cut Flowers

What’s on the show today?

How to stop your veggie garden from drying out in the Good Earth segment, sunflowers not for show but for seeds in Vegetable Heroes. Five senses-today’s it’s all about taste in Design Elements and more value for money cut flowers in the Talking Flowers segment with Mercedes.

THE GOOD EARTH

All About Wicking Garden Beds
Wicking pots, or wicking beds are nothing new, ask any African Violet society member.
They’ve been using wicks in their self -watering pots very successfully for years.

Just imagine though, if you had a veggie or other garden bed that uses this self watering idea.
That would mean your vegetable garden would get watering from below.
Let’s find out .
You can build a wicking bed yourself easily enough with recyclable materials.
Here's how Margaret put hers together.
Photo: Margaret Mossakowska
Use wooden crates from a fruit market and scoria if you can’t get vermiculite. 
Margaret sources vermiculite in bulk from pharmaceutical companies that use it as packing material.
Start with a frame, then line it with something like pond liner or even black plastic.
Lay in some aggregate and ag-pipes.
You need to build a 10 – 15 cm layer of this base on top of which you place a coil of ag-pipe connected to an upright pipe which is where you’ll fill with water.
Credit: Leaf Ninjas

On top of this, place a layer of geo textile fabric,a 10 cm layer of vermiculite then your best garden soil.
The soil shouldn’t be more than 30 cm high otherwise the wicking system won’t work. 
For veggies the soil should be 20 - 30 cm to give them room to grow.
Tip: Don’t forget to put in an overflow valve about half-way up the sides.
One more thing, it takes a week for the wicking system to start working properly after you first fill the reservoir, so don’t forget to water your vegetables everyday until then.

VEGETABLE HEROES:

Growing Sunflowers for Seeds.
You may have grown sunflowers in the past but did you grow them for just the flowers or just the seeds?
That seeds for eating that is.
Had you thought that all sunflower seeds are alike even?
Did you know that there’s a big difference between growing sunflowers, and growing edible sunflower seeds.
So that means if you’re interested in the edible seeds, you need to select your sunflower variety carefully.
Not just any old sunflower seed.
Certainly not the doubles, or pollenless sunflowers.
Sunflower Helianthus Annuus is in the Asteraceae family and started off as a wild sunflower growing in North America.
This sunflower was first cultivated around 3000 BC and some say it could’ve have even pre-dated corn as an Indian crop.
It wasn’t until the 1500’s when the Spanish took the seed to Europe to show off as an ornamental plant that the rest of the world knew about them.
By the 18th century, sunflowers were produced on a commercial scale for crushing, particularly in Russia where Peter the Great was a fan.
Russia was the world leader in production and breeding for many years so it should come as no surprise that there are some varieties with Russian in their name.
From the 1970's that, seed companies began to produce hybrid seeds which produce higher yields, oil content and resistance to disease.
Botanical Bite
Did you know though that the seeds in the sunflower head follow a remarkable spiral pattern.
This allows them to be packed into the head in the most efficient way.
The seeds sit against each other at the "golden angle" 137.5 degrees and head off in left and right spirals the number of which are Fibonacci numbers.

What’s Fibonacci-that’s another story.
What Does It Look Like?
I’m sure most people know what sunflowers look like but here’s a short description.
Sunflowers are annuals that have hairy, rough to touch central stems that grows to around 2-4m tall.
The leaves are dark green and egg shaped or perhaps more triangular.
The edges of the leaves are serrated.
The flower for seed production is bright yellow with a dark centre nodding on a long stalk.
The diameter of flowers varies from 10cm – 30 cm wide.
Sunflowers only seem to follow the sun when the plant is quite young and the stems more pliable.
Which Variety To Grow For Edible Seeds.
Mammoth Russian-grows 2-4m tall with thin-shelled seeds.
Sunflower Sunbird-an old heirloom variety that grows to 2m, can be used as a trellis for smaller climbing plants.
SunflowerYellow Empress-has flowers up to 25cm across, and grows to around 2m
Mammoth Grey Stripe-2-4m the seeds have lower oil and content so it’s good for birds such as caged parrots.
The only drawback is that it has a lower germination rate than those sold by bigger seed companies.
As a general rule, heirloom types of sunflowers will produce good quality edible seeds..
How To Grow

Sunflower seeds need to be sown directly into the garden.
The soil temperature needs to be a minimum of 130 C to germinate.
Hint: soil temperature is a few degrees less than air temperature as a rule of thumb.
For those districts that have late frosts, you still can sow the seeds two weeks before you’re expecting any frost.
But if there’s a snap when your seedlings emerge, sunflower seedlings can handle it.
For those of you wanting to start them in punnets or trays, you’ll have to be extra careful when you transplant them because all sunflowers grow a taproot.
Because of this taproot, if you have shallow soils, grow your sunflowers in raised beds so that the taproot can reach down to at least 60cm.
Sunflowers need plenty of room so space them out at least 30cm.
Sunflowers grow in open fields in Europe where they receive all day sun.
For the home gardener, the minimum of daylight hours is 6-8 hours.
As your sunflowers grow feed them regularly with any liquid feed, although they won’t mind a bout of hot weather.
There’s two things that sunflowers detest and that’s water logged soil and windy locations.
Can I Grow Them In A Pot?
Yes, there are dwarf sunflower varieties that you can grow in a pot. Check the label on the back of the packet.
When to Pick the seeds?
Cut sunflower heads when some of the seeds inside the edges appear ripe and fall away when rubbed, or when birds start harvesting them for you.
The seeds are usually ready 30-45 days after the flower opens.
Here’s a tip: Sunflower seeds are ripe when the flower head turns from green to yellow and the seed head begins to brown.
You can also give one a taste test though.
Store the seeds in a warm, dry place.
If the birds are going crazy for the sunflower seeds you can protect the heads with some old stocking, or muslin, even cheesecloth.

How to Eat sunflower seeds.
You can eat them raw or in a pasta or pizza dish.
Why not try making Sunflower seed pesto?
Crush them up and make a sandwich spread or in a dressing for salads or vegetables.
Sunflower seed Pesto
Ingredients:
3 cups basil leaves;
2 cloves garlic;
3/4 cup sunflower seeds
juice of 1 lemon
pinch of salt and pepper to taste;
3/4 cup olive oil
Option – try adding 3/4 cup parmesan cheese at Step 2 for a different flavour.
DIRECTIONS
Using a food processor, blender or mortar and pestle, finely chop/crush basil leaves and garlic.
Add sunflower seeds, lemon juice, salt and pepper and combine until seeds are finely chopped.
Add olive oil and combine.
Why are they good for you?
Most seeds are rich in protein, healthy fats, fibre, minerals such as magnesium, potassium, calcium, plant iron and zinc while being naturally low in sodium.
Just a handful of sunflower seeds contains significant amounts of magnesium, selenium, and vitamin E — a vitamin that protects the cells against free radicals and inflammation.
They are also contain vitamins B1,B2, B3 and some are rich in vitamin E.
The fibrous coat of seeds may prevent complete digestion so crushing seeds using a mortar and pestle prior to adding them to snacks and meals may help.
Try throwing some in your next pesto recipe!

Gardening for the 5 Senses: Taste
Probably one of the easiest senses to stimulate when it comes to gardening because it’s all about food and eating.
The sense of taste of course so how else can you stimulate the sense other than putting in a veggie garden.
Let’s find out.
Coffee bean tree.
I'm talking with Chris Poulton, Sydney Convenor for the Australian Institute of Horticulture and an experienced horticultural lecturer and consultant.


Our suggestion is to grow as many herbs as you can.
Don’t be limited by the fact you’ve only got a windowsill, or balcony garden because all you need is 4-5 hours of sunlight a day to grow these things.
Increase your taste range in the garden with some native bush tucker such as finger limes or those bromeliads which have fruits on them.
You could also try growing a coffee bean tree, Coffea arabica, pictured above.
Not only do you get the red berries but the flowers that appear all along each branch, are heavenly scented

Value For Money Cut Flowers

Cut-flowers are a luxury product and consumers demand a certain standard of quality and value for money.
How much would you like to spend on your cut flowers?
$35? $45? Or much more?
If you’re bit on the Scottish side, and moths fly out of your wallet when you open it you might want to consider those flowers that might cost a bit more but will last for up to two weeks in the vase?
Hang on, I think we all want that really don’t we?

But let’s first delve in to what happens between the grower and you the consumer.
Sure there’s roadside stalls where Jo the flower seller can you give you “quality flowers at a cut rate price.”
But how often is Jo there, and he’s growing them in his backyard.
What about the real grower?
This is how the chain goes, grower, then wholesalers, exporters, auctioneers, florists or supermarket buyers and the local shop.
So don’t whinge about the price of cut flowers, got it?
Alstromerias and Carnations
Here are some suggestions for long lasting flowers in the vase.
  • Carnations -2-3 weeks
  • Chrysanthemums-3-4 weeks ( bargain)
  • Astromeria-2 weeks
  • Delphiniums-2 weeks
  • Gladiolus-10 days.

Perfume, Sex of Flowers and Pesky White Flies

What’s on the show today?

Clouds of pests in the Plant Doctor segment, growing an ancient grain in Vegetable Heroes. Five senses gardening today’s it’s all about smell in Design Elements and the sex of flowers in the Talking Flowers segment with Mercedes.

PLANT DOCTOR

White Fly Control
Are you experiencing a cloud of insects fly up when you disturb some of your plants?
Maybe you’ve had that in the past and haven’t been successful in removing them from a particular plant.
Whitefly infestation
Sweet Potato Whitefly
If that’s the case, there’s things you can do about it before that cloudburst of insects descends onto your garden.
Let’s find out .
I'm talking with Steve Falcioni, Marketing Manager of www.ecoorganicgarden.com.au


Are you surprised that there’s several species of whiteflies?
Shooing them away every time you go out into the garden isn’t successful. 
The numbers will soon build up into the hundreds even thousands.

Symptoms:What To Look For:

  • Don't confuse them with scale, because the whitefly juvenile stage can look like scale.
  • If your not 100% sure that it's whitefly larvae that you're looking at,there are other symptomes to look for.
  • Whitefly are sap suckers and will ssuck the chorophyll ( green part) out of the leaves.
  • Whitefly also produce mass of honey dew to which, sooty mould will settle.
Control:
  1. You must take action because whiteflies suck the sap out of your plants’ leaves. 
  2. Botanical oils work the best but you need to be able to spray under the leaves. 
  3. Using a pump action sprayer with help with the underneath the leaves. 
  4. Do a follow up spray 3-5 days apart to get the juvenilies. 
  5. Neem is approved overseas for this problem on edibles but only on ornamentals in Australia. 
  6. Encourage lacewings into your garden because the love whitefly as much as they love aphids. 
If you have any questions about controlling whitefly either for me or for Steve, why not email realworldgardener@gmail.com or write in to 2RRR P.O. Box 644 Gladesville NSW 1675.

VEGETABLE HEROES;

Chenopodium quinoa: Quinoa
You’ll find it in bread, muffins, breakfast cereals and health bars, drinks and plenty more, but is it just a fad or is it something worth investing time in?
This is the ancient cereal grain, Quinoa (keen-wah) which some of us probably thought, should be pronounced like it’s spelt, and that is Quinn-o-ah. 

Botanical Bite

Quinoa is Chenopodium quinoa, in the Amaranth family ( Amaranthaceae).
It’s not a grass but rather a pseudocereal botanically related to spinach, amaranth. beets, and tumbleweeds
You might know the Amaranth flower and have even grown it in your garden.

Did you know that quinoa is related to some weeds and does in fact look a bit like the weed fleabane.
Quinoa’s origins dates back 3-4,000 years to Chile and Peru.
So what happened to this grain and why did it fall into obscurity until about the 1970’s?
Blame it on Spanish explorers who burned 99% of the quinoa fields in an attempt to eradicate Incan culture.
Because the seeds have a coating which contains bitter-tasting saponins, you won’t be able to eat them straight off the plant.
Most of the grain sold commercially has been processed to remove this coating.
The leaves are also high in oxalic acid, so best not to eat too much of them.
What Does It Look Like?
Quinoa grows to about 1-2m high, has big hairy lobed leaves around a woody central stem.
The flowers are like plume on top of a stem
After flowering you’ll see the fruits which are really small seeds, either black or red, depending on the cultivar of quinoa.

How To Grow
  • Quinoa is easy to grow, which shouldn’t surprise you being related to a weed.
  • Direct sow the seeds in late September to the end of October, while night temperatures are still cool.
  • Keep in mind. Quinoa seedlings aren’t frost tolerant.
  • The best soil temperature for germination is 18-24°C.
  • Anything over 320 C and it won’t germinate.
  • Keep the soil most otherwise your seeds will fail to germinate.
  • Sow the seeds about 5mm deep (that’s ¼” in the old scale).
  • That means you’re barely covering the seeds, and thin then out when they reach 10 cm in height.
  • Here’s a tip: because they look like weeds when they first emerge, show them in rows so you don’t confuse them with real weeds.
  • If you’ve got the conditions right, then the seeds should germinate in 4-10 days.
  • The spacing should be around 25-35cm (10-14″) between plants.
  • Perhaps you want to grow them for baby leaf production, then plants can be spaced closer together.
  • They’re slow growing for the first 10cm then seem to take-off after that.
  • Liquid feed them if you want to give them a kick along.
Can I Grow Them In A Pot?
Not really because they grow too tall.
When to Pick the seeds?
Wait until leaves have fallen off, leaving just the dried seedheads.
Usually that’s 90 – 120 days after sowing seeds.
Seeds can be easily stripped upwards off the stalk with a gloved hand.
Best to do this when the weather is dry.
A god idea is to bend over the seed heads into a large bucket and clip them off.
Working in a dry place, strip off the seeds and spread the seeds on screens or trays to finish drying indoors.
It can be left on trays in the hot sun or placed near an indoor heat source. 
Stir the seeds occasionally until they’re as dry as possible.
Store seed in air-tight containers in a cool dry place.
How to Eat Quinoa
Pomegranate Quinoa salad
Before cooking and eating quinoa, it must be washed.
The bitter saponin seed coating that keeps pests away is unpleasant to taste.
So, don't skimp on the washing.
Here’s some other methods for washing your quinoa seeds.
Remember saponin is very soapy so you have to wash it until the water rinses clear.
One method is to whirl the grain in a blender with cool water on the lowest speed, changing the water until it is no longer frothy.
It may take five or six water changes to do this.
Another technique is to put a loose-weave muslin bag or small pillow case of quinoa in the washing machine and run a cool-water rinse cycle.
Being a grain or really pseudo-grain, cook it up like you would rice.
Equal parts water to quinoa and steam or boil 12-15 minutes.
Why are they good for you?
Quinoa is high in protein.
Quinoa is a nutrient-dense food.
The grain is lower in sodium and is higher in calcium, phosphorus, magnesium, potassium, iron, copper, manganese, and zinc than the more common grains, including corn, barley, and barley.

DESIGN ELEMENTS
Five Senses Gardening: Smell or is it Perfume?
As gardeners you’ll already now that some plants have flowers that have smell or perfume, and some plants have leaves that have smell or perfume.
But if you want a really perfumed garden, you might want to think about including plants in the garden that you don’t necessarily need to crush, rub or touch to inhale their sweet perfume.
What does that mean you should do?
Let’s find out.
Magnolia Champaca
I'm talking with Chris Poulton, Sydney Convenor for the Australian Institute of Horticulture and an experienced horticultural lecturer and consultant.

Some suggestions for introducing more perfume into the garden that will pervade the whole garden.
  • Sweet Olive, (Osmanthus fragrans), 
  • Honeysuckle, 
  • Jasmines, 
  • Angel Trumpets, 
  • Michelia varieties, (now included in the Magnolia family) like Port Wine Magnolia; Magnolia Chamopaca, and many others.
All of these plants just throw their scent out into the garden without you having to lift a finger.
If you have any questions about five senses gardening or have a suggestion either for me or for Chris why not write in or email me at www.realworldgardener.com  

TALKING FLOWERS

Sex of Flowers
Complete Flowers: Incomplete Flowers
Bisexual: Unisexual
Plants can have complete flowers or they can have flowers with only male or only female parts.

Complete flowers, also known as hermaphrodite, or bisexual flowers have all the reproductive parts: the Stamens and Pistil ( stigma, style and ovary) inside the flower.



Examples of complete flowers, are tomato flowers ( self-pollinating) Hibiscus ( pictured), roses, tulips, passion flowers. 
  • The pollinator visits the flower and brushes past the stamens. 
  • When the pollinator visits the next flower, the pollen is rubbed onto the sticky stigma. 
  • If it's the right type of pollen ( fits the opening) then the flower will be pollinated resulting in some sort of fruit.
Flowers which only have male or female or called Unisexual .
Some examples are watermelon, cucumber, zucchini, pumpkin,white mulberry,coconut flowers,and birch.
For fruits to occur, pollinators must visit the male flower first then transfer pollen onto the female flower. 
Can be problematic sometimes when only male flowers appear on some cucurbits for the first few weeks.
