Lanterns Light Up the Garden

PLANT DOCTOR

Scale of Citrus

Female scales don't need to mate to lay eggs, but they die straight after laying those eggs and crawlers that hatch can remain under the body for a few days.

These pests are very tiny when they hatch, around 1mm in size, so undetectable to the naked eye.
As they get older they build a protecting coating where they are pretty much untouchable by anything that you want to throw at it.
Once crawlers have found a place that suits them as a feeding site, the insert their piercing mouthparts into the plant and begin to produce a waxy coating.
So the best time to treat your plants for scale is now when they’re unprotected.
Let’s find out about what the different scales look like and how to treat them.
I'm speaking with Steve Falcioni from www.ecoorganicgarden.com.au


Citrus Louse Scale
Did you know that there’s a ladybug that disguises itself as pest, almost looking like cottony cushion scale or mealybug but the difference between it and the pest that it resembles and eats, is that it’s relatively fast moving?
In fact this ladybug climbs up and down the twigs and branchlets looking for the mealybug dinner.
Mealybugs on the other hand, tend to hide in cracks and crevices of your plant and don’t really move much at all.

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.
Some pretty famous people have been known to be fans of cucumbers, even cucumber pickles.
Take, Julius Ceasar, he ate them everyday, Cleopatra, thought cucumber pickles help her skin complexion, and other pickle lovers included George Washington and Queen Elizabeth 1.
Would you have thought that Cucumbers are one of the world’s favourite vegetables?
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 15-33°C.
Cucumbers are happiest when the average temperatures are around 210C
Sow the seeds of Cucumber in late Spring and early Summer for cool temperate districts, spring and summer for arid and temperate zones districts, 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?
growing cucumbers commercially
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.
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.
Gives you lots of fruit per plant and it’s burpless
Or you could try Cucumber Mini Muncher as well.
Available from www.diggers.com.au
The best thing is that Cucumbers aren’t picky about soils.

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.

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.
Flowers of Cucumbers
Powdery mildew is a fungal disease that is spread by spores carried by the wind.
Look for white to grey fungal deposits on the leaves and stems of your cucumbers. As the mildew spreads, the leaves become brittle then start to die off.
There are some types of cucumbers that resist this disease for a time anyway.
You can also try a natural fungicide. 1 part whole milk to 10 parts water, and spray in the cool of the day.
Don’t forget to feed your cucumber plants every couple of weeks with a soluble plant food.
There’s so many now on the market, and some come with seaweed added into them as well.

Who out there hasn’t tried a cucumber that’s tasted bitter?
I’m sure some time in your life, that’s happened hasn’t it?
There’s seems to be a few theories for bitterness in cucumbers
One theory is that the bitterness is caused early in the plant’s development by terpenoid compounds that give a bitter flavour to the entire plant.
Usually the bitterness accumulates at the stem and below the surface of the skin of the cucumber.
According to this theory it’s a genetic problem.
Newer cucumber hybrids seem to have fewer problems with bitterness.
I’ve always thought it to be the result of Cucurbitacin.
Found in most cucumber plants, Cucurbitacin causes fruit to taste bitter.
Cucurbitacin levels increase when a plant is under stress, and can make the fruit taste really bitter.
The concentration of these compounds varies from plant to plant, fruit to fruit, and even within the individual fruit itself.
Did you know that the ability to taste detect bitterness or cucurbitacins also varies from person to person.
Even insects have varying preferences for cucurbitacins- the compounds attract cucumber beetles but repel other insects, such as aphids and spider mites.
Anyway, it proves that you shouldn’t stress out your cucumbers!
By the way, if you do get a bitter cucumber, peel it and cut of the ends by about 2.5cm, that’s where the bitterness concentrated.
Just like zucchinis, cucumbers have separate male and female flowers. Male flowers come out at first, but don’t worry too much because the female flowers will arrive soon after. Cucumbers should be ready at about 50-60 days and picking fruit often stimulates more to start growing.
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!

TOOL TIME

Do you wear garden gloves when you’re doing jobs in the garden?
Garden gloves come in all shapes, colours, materials.
Some last really well, others don’t and you probably won’t buy them again.
Garden glove selection; leather gauntlets are good for rose pruning.
But why wear garden gloves?
Let’s find out if wearing gardening gloves is really that important. I'm talking the Tony Mattson, General Manager of www.cutabovetools.com.au
  From spider bites, to ingrained dirt, gardening gloves protect your hands but not all gloves will work for all the situations in your garden.
That means you might have to have several different types on hand in the gardening cupboard, or under the sink in the laundry.
Leather gloves for rose pruning or pruning prickly plants, waterproof gloves when digging around in wet soil or potting mix, and all round gloves for general jobs.

Rubber gloves are good for wet work and thermal gloves are great for cold days.

If even you’re just picking up leaves, gardening gloves protect from unexpected nasties lurking amongst them.

Important: Try the gloves before you buy them.
They need to fit like a ahem, glove. That means there is no space at the top of your fingers and no gap in between the fingers of the gloves.
All gloves are made to a price point. You can buy them for as little as $5 or as much as $50 dollars






PLANT OF THE WEEK

Abutilon x hybrida Bella, Chinese Lantern
The common name for this plant reflects what the flower does.Hanging down like a lantern but until now, the bush grew quite big, around 2 - 4 metres tall and almost as wide.
In comes these relatively new introductions that are really dwarf plants, but with the same size flowers so they can be squeezed in anywhere. Who can resist?
Let’s find out about them. I'm talking with Karen Smith editor of www.hortjournal.com.au and Jeremy Critchley owner of www.thegreengallery.com.au


PLAY: Chinese Lantern_16th December 2015
The really dwarf varieties of Chinese Lanterns are the Abutilon Bella series.



Bella Pink

Bella series lanterns grow to 30cm tall and slightly wider.













They really can be squeezed into any spot in the garden if you have a semi-shaded spot or because they only grow small, potted Chinese Lanterns would be great as well.



Chinese Lanterns grow well in most parts of Australia, except for the very cold mountain zones.

In inland areas be sure to water well and keep protected with mulch.

In hot inland climates Abutilons appreciate some light shade.

Chinese lanterns flower for such a long time, from Spring right through to Autumn so if you do have room for some more plants, even a small bit or room, I recommend growing several.
Pruning is not required.
