Problem Solving That Pest Invasion.
Spring has well and truly sprung but what else is booming in your garden?
 Just when you’re not really looking to closely, some of the pest bugs are multiplying on a grand scale and before you know it, you’re fabulous garden has become a supermarket for mini-intruders who aim to make a meal of your flowers and leaves.
Let’s find out how to stem this invasion in the garden.

White wax scale on citrus.

Everything from aphids, whitefly, scale, to fruit fly and caterpillars, are having a banquet at your expense until the good bugs can build up sufficient numbers to deal w
ith them.
Scale are pretty much invisible because they're very tiny and because they have legs at this stage of their lifecycle, they're called crawlers.


Fruit fly

You'll only realise you have scale when you see the next life cycle when they have created that waxy outer shell which is impervious to sprays.
So if you have had scale in the past on the plant year after year, then be pro-active and spray with botanical Eco Oil from eco organic garden's range.
It just goes to show that you can’t be complacent when it comes to gardening especially at the start of the warmer months.


You might think the cold weather knocked of most of your pests, but insects are resilient and they make up 60% of the world’s living things.
Did you know that there’s at least 6 million different species of insects in the world today and Australia has 220 thousand different species?
They are an amazingly diverse group of animals that have conquered almost every environment on earth and some of them benefit out gardens whilst others seem to enjoy them to our detriment.

VEGETABLE HEROES

Cucumbers or Cucumis sativus..
Cucumbers just love the hot weather, so they’ll germinate and grow quickly at this time of the year.
Cucumbers are a member of the gourd or cucurbita family and have been grown for 4000 years!
Did you know that Cucumbers were widely eaten throughout Asia and Europe by the 6th and 7th centuries A.D?
Did cucumber start off in India?
No-one’s really sure although some sources point to somewhere in the lower Himalayas where the ancestor of the cucumber was probably a plant with 7 pairs of chromosomes and small, very bitter fruit.
Some pretty famous people have been known to be fans of cucumbers, even cucumber pickles.
Apart from just eating cucumbers they were also widely used as a source of several medicinal remedies .
They treated everything from bad eyesight, scared mice, and cured scorpion bites

Cucumbers photo M Cannon

According to legend, in Ancient Rome during the short reign of Emperor Tiberius (14 – 16 AD) he demanded to eat cucumber on every day of the year.
During summer special gardens were tended just for his vegetables, and in winter cucumber was grown on moveable bed frames that were moved to be exposed to the sun, or illuminated with the mirror-stones.
Cucumbers are the fastest and easiest of vegetables to grow so say some gardeners.
I would’ve thought radish, but maybe they’re a close second.
When is the best time to grow some cucumbers?
Cucumber plants do best in all types of temperate and tropical areas and generally need temperatures between 15⁰-33°C.
Cucumbers are happiest when the average temperatures are around 21⁰C
Sow the seeds of Cucumber in late Spring, say October and early Summer for cool temperate districts,
Spring and Summer for arid and temperate zones district

s, from August until March in sub-tropical areas.
Only the cooler months for tropical areas-so April until August unless you’re inland.
And where can you grow these delicious cucumbers?
You need to pick a sunny, well-drained spot, because Cucumbers are a subtropical plant, that needs full sun.
Cucumbers also want a decent amount of growing space in your garden.
If you’re short on space, try growing them up vertically on a trellis or even on some netting, perhaps a tomato trellis?

Greenhouse cucumbers photo M Cannon

In fact, growing up a trellis would be a great way to avoid all the mildews and moulds that cucumbers are prone to in still humid weather.
So Which Cucumber Should You Grow?
The list is pretty long but you have to decide between regular and burpless varieties to begin with.
Then do you want slicing, or pickling cucumbers?
After that, heirloom or greenhouse varieties.
The burpless varieties don’t need peeling which is an added bonus and would be the way to go if cucumbers repeat on you.
Pickling Cucumbers are shorter, stouter, and have a rougher outer skin, as well as drier flesh that allows them to soak up more of the brine they’re pickled in.
Obviously cucumbers for slicing need to be straight.
The ones you see in the supermarket are regular English cucumbers, usually long thin with a dark green skin.
Great for slicing, and not suitable for pickling.
Let’s start with cucumber “Sweet and Striped” that can grow to a metre long but it will curl.
Japanese Climbing, is flavoursome and the fruits are good for eating fresh or pickling. This one’s burpless.

Armenian cucumber

Ever heard of Armenian cucumber?
This cucumber is a pale almost limey green, it’s burpless with drier flesh so it can be stored up to one month.
Great for slicing or pickling.


Lemon Cucumber

My favourite is Cucumber 'Lemon'
'Lemon' is an apple type, heirloom variety, introduced in 1894.
The fruits are round, sweet and crisp with a thin yellow skin and white flesh.
It can be eaten like an apple and is easy to digest.
This cucumber is a good all-rounder because I can be used for salads, pickling and slicing.
For regular eating there’s Lebanese Cucumber 'Beit Alpha'
A Lebanese style of cucumber is thin-skinned, dark green, tender, and burpless.
This one can grow cucumber, up to 30 cm long.
If you pick it when it’s smaller, it has the best flavour whether pickled or fresh and is never bitter.
Lebanese cucumber vines bear early, are disease resistant and very productive
There’s also a number of dwarf varieties if you’d like to grow your cucumbers in pots.
Try Mini White- one of the most popular.
The 10cm long fruit and is best picked when young.
This one gives you lots of fruit per plant and it’s burpless  
Or you could try Cucumber Little Potato which as the colour or a potato or Kiwi fruit, with a zesty lemon burpless inner flesh.
Then there’s Cucumber 'Spacemaster'
'Spacemaster' is a bush variety, 90 cm across; suitable for growing in containers. Fruit is slender, dark green, 17 - 22 cm long with a crisp, sweet flavour.
It’s supposed to be disease resistant.
Good for salads or pickles, if picked young.
You’ll need to go to a seed mail order place for some of those, or if you’re in Adelaide or Melbourne, go to the shop in the Botanic Gardens.
The best thing is that Cucumbers aren’t picky about soils.
Parthenocarpic Cucumbers What?
Did you know that you can grow a seedless variety that doesn’t need pollination?
In fact, pollination creates an inferior fruit so these are best grown in a closed environment such as a greenhouse.
This type of plant is called parthenocarpic which is just the name of a plant that can produce fruit without pollination.
So what’s a cucumber plant that needs pollination called?
Gynoecious.
Gynoecious varieties have mostly or only female flowers ― the flowers that produce fruit ― and typically are earlier and have higher yields.
And do you get this information from seed packets?
No because most of the seeds you can buy are monoecious cucumbers which as male and female flowers.

Cucumber flowers photo M Cannon

In a monoecious cucumber ( nongynoecious cucumber) plant, the first 10–20 flowers are male and for every female flower 10–20 male flowers are produced.
I’m not sure if I’ve ever seen that information on the back of a cucumber seed packet?
However, do you find your Cucumber seeds sometimes don’t germinate?
They’re big seeds but if you’re raising them in punnets and the seed raising mix dries out, then the seed most like has dried up as well;
And if you keep it too wet, then the seed rots.
If this keeps happening, try using another type of seed raising mix, or even some good quality potting mix and try again.
What cucumbers like is soil that’s well-draining and has a pH of around 6.5.
Add in plenty of organic compost and fertilisers like chook poo or cow manure.
I’ve seen an idea where you make mini mounds, wet the soil first and then drop in 4 -5 seeds into the top of each mound.
Mulch the mounds so they don’t dry out but not too much or you’ll be wondering why nothing is germinating, that’s because the seed has rotted away.
When your seeds have germinated, pick out the strongest couple and throw away the others so you don’t get overcrowding.
When your cucumber has gotten going, water it regularly at the base of the plant, that way the leaves stay dry and you lessen the chances of the leaves getting the white powdery stuff growing on them, powdery mildew disease.
Cucumbers should be ready at about 50-60 days and picking fruit often stimulates more to start growing. Some of you probably have realised that if you pick your cucumbers when they’re quite small, this is when they’re at their sweetest.
Twist the cucumbers off the plant or cut the stalk just above the cucumber tip.
They keep for 7-10 days in the fridge then the start to look like something that came from outer space…green and slimy
Why are they good for you?
Cucumbers have lots of Vitamins C but why you should eat them is because the silica in cucumber is an essential component of healthy connective tissue, you know, like muscles, tendons, ligaments, cartilage, and bone.
Cucumbers have some dietary fibre and Cucumber juice is often recommended as a source of silica to improve the complexion and health of the skin, plus cucumber's high water content makes it naturally hydrating—a must for glowing skin.
So eat them quick in sandwiches, salads or juice them for healthy glowing skin!

DESIGN ELEMENTS

This series is about garden styles which RWG has visited over the years with different designers.
Have you ever wondered what makes up a formal garden style?

Palace of Versaille Garden photo M Cannon

Perhaps you like neat lines and clipped edges without too much fuss and frippery?
Can you have a formal style in your garden and how hard is it to maintain?
All these questions are answered and more so let’s not wait any longer.
I'm talking with Landscape Designer and consulting arborist Glenice Buck 
PLAY: Garden Styles_Formal garden_28th September 2016
A traditional formal garden is the most structured and rigid in their style. 

The designs are usually symmetrical in their layout and the number of species used is minimal.  The gardens tend to run in straight lines and form grid like patterns. 

The main axis’s of the gardens are formed by pathways (in grass or stone) that will stretch out across the site and where they intersect, a focal point such as a statue, a water feature or a urn will be placed.   I

t is usually the scale of these focal points which give the gardens a feeling of grandeur. 

The plantings in these balanced gardens are stylised into the orderly shapes of hedges in varying heights, avenues of trees and topiarised plants in all shapes and sizes. 

There you go, it seems that the formal style of garden isn’t that hard to maintain or establish.
 Choose a plant for those hedges that suits your area then make borders with it.
Inside the borders grow anything from roses to peonies and voila’  instant formal style .

PLANT OF THE WEEK

Sydney Rock Orchid; Dendrobium speciosum
There’s  many a garden that gets sucked into the vortex of admiration of orchid flowers.


Sydney Rock Orchid photo M Cannon

Orchid flowers are just so spectacular to look at but don’t they need a shade-house or green-house at least?
Not for this one and it’s one that you probably should have in your garden.

PLAY: Dendrobium_28th September_2016

The Sydney Rock Orchid or Dendrobium speciosum   is one of the worlds’ most underrated and exciting of orchids.
This rock orchid has the largest display and most spectacular shows of mass blooming of any known orchid.


Dendrobium speciosum photo M Cannon

The showy flowers grow in long racemes on straight or slowly arching, long, starchy stems with over 100 small sweetly fragrant flowers per stem from August to October.
Attach it to trees with some wire or twine and the root system will eventually attach itself, although this takes up to two years.
Extraordinarily tough, hardy and drought tolerant it should be one of the best cultivated plants ever!
Avoid frosts, unaccustomed hot sun, too much shade (make sure you can see a shadow when placing hand above foliage) and temperatures above 36⁰ C if possible. .
Give D. speciosum needs plenty of food in the form of fertiliser.
Not just a spray with something once or twice a year, but a continuous regime of well balanced fertilising

WILDLIFE IN FOCUS

With a wingspan of up to 2.5m, and standing at least one metre tall, the Wedge-Tailed Eagle is the largest raptor in Australia.
A lanky bird, it hunts by flying up to 2 kilometres high, circling on thermal air currents for as long as 90 minutes and sailing out over the countryside, covering wide areas .
When flying, the wings have distinctive flight tips and its tail fanned and wedge shaped.
Let’s find more. I'm talking with Dr Holly Parsons, Manager of www.birdsinbackyards.com.au

the Wedge-Tailed Eagle is found throughout Australia, including Tasmania and will aggressively defend their territory, even against drones.

Wedge Tailed Eagle

Earlier this century, when eagles were found on dead sheep and lambs, it was thought that they had killed them.
Bounties were paid to farmers for shooting them, (In one year in Queensland 10000 bounties were paid and between 1927-1968 in Western Australia another 150000.)
All that has stopped once people realized that the eagles usually attack only poor, dying or dead lambs and have little effect on the sheep industry. Today they are protected in all states.

VEGETABLE HEROES

GREEN TOMATOES

Aunty Ruby's Green

This segment won’t be complete without mentioning them at least once every year, because there’s always so much to be said about them.
Why? Because we just lover our summer tomatoes that taste better than the store bought ones, and once you get the conditions right, they’re relatively easy to grow.
There’s books written about them, they are prone to all sorts of pests and diseases, but every year, we plant them hoping for that ultimate crop.
tomatoes, or Lycopersicon esculentum.
Being in the Solanaceae family, they’re related to eggplants, capsicums, chillies and potatoes.
Tomatoes are botanically a fruit, or to be even more accurate a berry, because they are pulpy and have edible seeds.
Other botanical fruits classified as vegetables include squash, cucumbers, eggplants, and peppers.
The tomato is native to South and Central America, and the first tomato was thought to bear a yellow fruit and grown by the Aztecs.

Wild tomato plants are still found in the countries between Ecuador and Chile as well as on the Galapagos Islands, although only two have edible fruit.
Did you know that it’s thought that people were growing crops of tomatoes at least around 500 BC?
In the mid 1500’s, tomatoes were only grown amongst flowers in Italy.
They certainly weren’t eaten.
As late as the 18^th century, physicians thought tomatoes caused appendicitis, and stomach cancer from tomato skins sticking to the lining of your stomach.
Europeans then refused to eat tomatoes because they were thought to be poisonous, and no-one was volunteering to be the first.
Why do a lot of store bought tomatoes have little taste?
The answer is because it’s a result of breeding tomatoes which ripen uniformly red.
This change occurred after discovery of a variety in the mid 20th century which ripened evenly, so was  then cross-bred  with just about every tomato variety, to produce attractive red fruit without the typical green ring surrounding the stem on uncross-bred varieties.
Before the introduction of this trait, tomatoes were able to produce more sugar during the process of ripening and were sweeter and tastier.
Usually, tomatoes turn red when ripe, but some varieties stay green.
These are the ones that we will concentrate on.
The usual concern or question is, how do you tell when green tomatoes are ripe?.
The colour green will change from a very bright green to a greeny-yellow tinge.
It’s a subtle change but once you’ve seen it you’ll know that it’s a reasonable difference.
If you’re still not sure how to tell if a green tomato is ripe and not just an unripe fruit,  close your eyes and feel it; if it's soft, it's ripe.
Some varieties for you to try are:
Green Zebra.

Green Zebra tomato

This is a very productive tomato, about 5 cm’s round that ripens to a beautiful amber gold with dark green zebra-like stripes over the amber background.
Inside, the flesh is a beautiful, sparkling green.
When those stripes appear, then you know the tomato is ripe.
Then there’s Aunty Ruby’s Green, is a luscious green big  sweet beefsteaks, bursting with a fragrant, complex, spicy-sweetness with a touch of tang.
Great for slicing.
A gorgeous green-when-ripe colour, this much sought after variety is a real treat to have in your garden, and is said to be the very best tasting green.
For the novice gardener this one you might need to tell by feel if it’s ripe though.

Green Grape tomato

Another favourite is Green Grape.
This one has an olive green skin, but is very sweet with a hint of lemon zest.
Last year it won the tomato taste test at the Botanic Gardens in Sydney.
A very compact plant ready to eat fruit in 10 – 12 weeks.
When to Grow Tomatoes?
There’s a tomato for every type of climatic condition and generally they’re a warm season fruit even though we call them vegetables.
In temperate climates you can plant them until December, hopefully some of you started them in early September to get the jump on fruit flies.
 In sub-tropical and tropical areas, this week it’s your turn to win, and yes, you can plant tomatoes all year round.
In cool temperate districts you have from October until December, and in Arid areas from August until March, so nearly all year.
What Do Tomatoes Like?
Tomatoes prefer full sun but if you live in very hot climates, you’ll get sun scald on your tomatoes, so afternoon shade of some sort is essential.
Growing tomatoes has to be in full sun at least 6 hours.
Tomato seeds can be planted into the ground as soon as the soil temperature reaches 20⁰C.
For cool districts I recommend that you start your tomatoes off in punnets of some kind and place this in a plastic bag or mini-greenhouse.

Greenhouse tomatoes

Before your transplant your seedlings from the seed tray, and this applies to all seedlings, you need to harden them off.
That means taking them out of a protected environment and putting them into 50% shade for a few days.
TIP:When you plant your seedling, this is about the only plant I know that you pile the soil higher than it was in the pot-that way, it grows extra roots to support the plant.
At the same time, put in a tomato stake of some kind and sprinkle some Dolomite around the plant.
ANOTHER GOOD TIP is to put some hydrated or fluffed up water crystals in the bottom of the planting hole, especially if in your district it’s very hot during the day, that it’s sometimes hard to keep the water up to them.
They actually need lots of water to prevent a problem called “blossom end” rot, when they get a black bottom.
Which also means a lack of Calcium. But you put on the Dolomite didn’t you?.
Don’t crowd your tomato plants because they need good air circulation around them so that fungal diseases don’t take hold.
When your tomato plant has four trusses (or branches of flowers) nip out top of the plant. By this stage you should have plenty of fruits forming that need to grow and ripen.
You could do this mainly because you want the plant to put all its energy into these potentially succulent fruits. And…you don’t want it growing taller than you tomato stake and flopping all over the place.
Keep the soil moist by regular watering and using a mulch of some kind.
Once the flowers have formed, you need to feed weekly with tomato fertiliser or a general fertiliser but add a side dressing of sulphate of potash.
Tomato feed is very high in potash.
Be careful not to overfeed as this can lock up other elements in the soil / compost that the plants require.
HINT: tomato plants will only s

Homegrown tomatoes

et fruit if the temperatures don’t drop below 21⁰C.

Did you know that a tomato picked at first sign of colour and ripened at room temperature will be just as tasty as one left to fully mature on the vine?
VERY IMPORTANT: Prune off the lower leaves to allow more light, improve air-circulation and prevent the build-up of diseases.
For some listeners, fruit fly will be a problem.
There are lures and preventative organic sprays that contain Spinosad.
 I intend to trail fruit fly exclusion bags. As soon as the fruits appear, on they go.
WHY ARE THEY GOOD FOR YOU?
First the good news, there have been studies done which show that eating tomatoes lowers the risk of some cancers. Possibly because of the chemical lycopene that is found in tomatoes and makes them red.
Cooked tomatoes are even better because the cell walls get broken down releasing something called carotinoids. Eating tomatoes with a small amount of fat, like some olive oil in a salad, allows the lycopene part to absorb better.
Tomatoes are highly nutritious and sweet because of natural sugars – sucrose and fructose.
If you ate only one tomato a day, you would get 40% of you daily requirements of Vitamin C and 20% of Vitamin A.

Garden Styles: Cottage Gardens.
This series is about garden styles which RWG has visited over the years with different designers. 
It’s always good to revisit these styles to find out differing views as to what makes up the unique garden styles. 

Cottage Garden Cotswolds

You may not have a particular style in your garden but after hearing this series you may want to incorporate some of the plants that make up the various styles. 
We’re starting of with a cottage garden style.
Let’s find out more.I'm talking with Landscape Designer and consulting arborist Glenice Buck

 Some of the main ideas of a cottage garden are not dependent on the exact plants but on how that garden is arranged, and how the plants are cared for.
Low growing perennials make up the backbone of a cottage garden with some accent plants here and there.
But what’s not evident is those clipped shapes but instead plants that are allowed to grow into one another.

Scampston Cottage Garden UK. photo M Cannon

A cottage garden is known for its pretty flowering perennials. 

These gardens have a relaxed feeling with their informal style rather than a grand presence.  

 The plants are usually fluffy flowering plants seemingly growing into each other in peaks and mounds. The plantings are rarely in straight lines. Hedges would only be found on the outside or as boundaries of the garden.  Narrow winding pathways would meander, allowing visitors to wander and explore the garden.

PLANT OF THE WEEK

Agonis flexuosa "Jervis Bay After Dark." Willow Peppermint
Plants with dark foliage make an attractive statement in any garden. 
They also break up the amount of green that you have in the garden and provide a striking contrast..
If gardens in England are anything to go by, then you won’t find a garden there without a plant with dark foliage. 
The people that market plants have their fun though and this one’s ready to party. 
So let’s find out more. I'm talking with the plant panel: Karen Smith, editor of Hort Journal www.hortjournal.com.au  and Jeremy Critchley,

PLAY: Agonis Jervis Bay After Dark_21st  September_2016 
Willow peppermint or Agonis flexuosa Jervis Bay Afterdark is a slow grower but give it a sunny position and it can take most soil types along the east coast of Australia.
Prune it to whatever shape your like or let it grow all wispy and willowy. 
Just feed it with native fertiliser.  

If you're wondering how this plant got its name of'Jervis Bay' which is a location in New South Wales while Agonis flexuosa is native to Western Australia. 
The name marks the nursery where this dark-foliaged selection was made. 
Most native plants in the 70s and 80's were grown from seed in nurseries around Australia so quite often there were mutations of a variety of species.
This was a particular selection that was selected in 1985 as a spontaneous seedling mutation in a flat of Agonis flexuosa grown by R. and M.L. Turner at Jervis Bay Nurseries.
