Incorrect plant labelling problem confirmed

Incorrect plant labelling continues to be a significant problem for South Australian gardeners.
More than 55 percent of gardeners responding to a Good Gardening newsletter/ABC TalkBack Gardening plant labelling survey reported an incorrect labelling problem this season.
This is very similar to the 57 percent figure recorded last season.
While there has been a slight (7 percent) improvement in the labelling of tomato seedlings, the survey again confirmed the problem is not confined to tomatoes.
Just over one third of respondents indicated incorrect labelling had also occurred on a range of other plants, particularly ornamentals, herbs, deciduous fruit trees and citrus.

Summary of results

Did you have a problem with incorrect plant labelling this season?
Yes    55.5 %
No    45.5 %

Were your tomato plants incorrectly labelled this season?
Yes    48.7 %
No    51.3 %

Were these tomatoes:
In single containers    54.8 %
Seedlings in a punnet 54.2 %

Have you had problems with incorrect labelling on other plants?
Ornamentals 43.8 %
Deciduous fruit trees 26.6 %
Herbs 23.4 %
Citrus 17.2 %

These survey results will be forwarded to representatives of the garden industry for information and comment.
Our thanks to those Good Gardening newsletter readers who took part in this survey.

Warm autumn a boost for beneficial insects

Gardeners who have stopped using toxic chemicals to control insect pests are about to be rewarded – big time.
Following warm, dry autumn conditions, there has been a big build-up of hover flies, assassin bugs and predatory wasps.
These are the good guys and they are currently on a mission to seek out and devour as many caterpillars, aphids and mealy bugs as possible, before they hibernate through winter.
As a bonus, you can expect a big population of pest-destroying beneficials in your garden early next spring.

Join SA’s fruit fly eradication program

If you grow fruit and you like the thought of harvesting crops that are not infested with fruit fly, join with your neighbours and carry out a regular check of all fruit still growing on your trees (also windfalls) for signs of fruit fly larvae.
If you are not sure about any critters you find, ring the Fruit Fly Hotline
1300 666 010.

Feed fruit trees after harvest           

Once harvest is over fruit trees should be rewarded with a small quantity of balanced fertiliser (nitrogen, phosphorus and potash). 
This will help improve both flowering and fruit set next spring.
Follow the product's application rate carefully, as manufactured fertilisers are more concentrated than organic products. 

Leafy landscape sets off a stately villa

⁠This large, leafy garden beautifully complements the architecture of the lovely old villa-style home.
Beneath big trees, expansive lawns are bordered by lush garden beds filled with flowering plants and a sprinkling of contrasting silver foliage.
⁠The garden and its professionally-designed landscape is one of 12 which will be open to the public during the SA Landscape Festival on the weekend of April 10 and 11.
Hedges add a dash of formality as well as loosely creating garden ‘rooms’. Several superb sculptures enhance the planting.
The outdoor entertainment area, along with the fire pit, tennis court and pool, all softened with an easily-maintained garden make this the perfect lifestyle property.

Innovative design ideal for entertaining

A surprising number of productive plants have been cleverly and creatively combined with ornamentals to make an inspiring garden space suited to relaxation and entertaining.
Several contrasting but complementary surface materials have been used unconventionally and add to the individuality of the garden, which also features in the SA Landscape Festival.
A firepit and a wow-factor feature created from tall tubular planters add to the innovative character.
Dotted with fruit trees, vines, veggies and herbs, this garden is far from the traditional productive plot!

Brighten your garden with viola faces

Bright little flowers or ‘faces’ on violas literally jump out at you, providing an abundance of colour and character to your garden.
Flowering from autumn through to late spring, these annuals provide months of colour.
Violas are best grown in all-day sun with good drainage.
They look great planted as a border, in a garden bed or just softly spilling over pots.
Viola flowers have a lovely soft fragrance and are easy to pick. As the flowers finish, Easy Colour suggest you remove any spent blooms to encourage repeat flowing.
They also recommend using a liquid fertiliser every 2-4 weeks to keep plants thriving and blooming for longer.
When buying violas look for Easy Colour’s distinctive purple cell packs. The cells are larger than other seedling punnets and designed to reduce transplant shock, ensuring your plants begin growing straight away.

Violas are in stock at Heyne's Garden Centre, Beulah Park, Semaphore Pets & Gardens and Barrow & Bench, Malvern and should be available at other good gardening centres.

Sundancers fuchsias for all seasons

Sundancers are a new type of fuchsia selected for their ability to tolerate hot summer weather and to flower consistently all year round.
This tolerance to heat comes from a root system that is more widespread and much deeper than most hybrid fuchsias.
The result is a strong growing bush, up to 2 m high and 1.5 m wide.
Don’t be surprised if your Sundancer fuchsia bushes are in bloom all year.
In SA growing trials Sundancers have flowered consistently, unprotected (including summer) over the past two years.
In the garden, mulching is recommended, as it is important to keep the soil around their roots evenly moist.
Too keep the plants flowering profusely, regular fertilising is also recommended.
However, container-grown plants will benefit from light shading through the hotter months.

Proven WinnersFuschia Sundancer are in stock at Heyne's Garden Centre, Beulah Park, Semaphore Pets & Gardens and Barrow & Bench, Malvern and should be available at other good gardening centres.
Unconditional Love

Unconditional Love – a beautiful new pink rose

Unconditional Love is a gorgeous pink hybrid tea rose and a sport from the favourite “Love You” rose.
The bushes produce large, pointed buds that are medium pink all over.
These unfold to form beautiful spiral shaped blooms. The foliage is lush dark green and has a silvery reverse.
This is a perfect rose for picking as a cut flower – it has very strong fragrance.
Unconditional Love is a tall bush up to 1.6 m high and produces a prolific number of roses, creating an awesome display in your garden.
Unconditional Love is a new release rose that has just been listed at Knights Roses for pre-ordering with delivery during winter.

How safe are animal manures         

Many gardeners like to use animal manures as an organic fertiliser when growing vegetables.   
While a number of pathogens in animal manures can cause illness, E. coli is of particular concern, as you only need a few microbes to cause human health problems. 
E. coli is also incredibly robust, surviving extended periods of drought and low temperatures.  Fortunately, it is destroyed by heat, particularly cooking.

Reducing animal manure risks   

In the home garden, the biggest risk occurs when the animal manures are fresh. 
  • Ageing animal manures (3-4 months) helps reduce the risk.
  • Composting destroys the bacteria providing the compost generates considerable heat.
  • Soil incorporation will also eliminate the risk as the E. coli bacteria will be destroyed by beneficial soil microbes. However, you should wait six to eight weeks before replanting vegetables.

A better way to control damaging lawn grubs

If you are relying on spraying your lawn continually with toxic chemicals to control lawn grubs, there is now a safe and effective alternative.
A new lawn product Grub Kill and Protect for Lawns, released by Yates contains acelepryn – a new-age chemical that stops lawn grubs, particularly lawn beetle grubs, in their tracks.
Acelepryn is a new class of chemistry that stops lawn grubs from feeding.
It’s action is rapid and it will continue to protect lawns against curl grubs along with a wide range of other common lawn pests for up to 6 months
The Yates product is an unscheduled poison and it has a low toxicity to most non- target organisms.
It is safe to use on all types of lawn including lawns in council playgrounds.
It is also safe to bees and earthworms.
Yates Grub Kill and Protect for Lawns is available from most garden centres and garden outlets.

End-of-season control for codling moth

Codling moth populations can be reduced significantly at the end of the fruit growing season by taking advantage of the grub’s need to over-winter in cracks and crevices of the trunk and branches of host trees.
Early in autumn, try wrapping a 20-30cm wide piece of corrugated or thick cardboard around the trunk of your tree. 
For large fruit trees, also wrap the lower section of main branches.
As the crops mature, the grubs exit the fruit and will seek over-wintering refuge behind the cardboard, rather than search for a suitable winter hiding place. 
The cardboard should be removed and destroyed early in winter along with the overwintering larvae.

New organic fertiliser for all garden plants

eco-aminogro is a certified organic liquid fertiliser made from recycled marine wastes and is high in valuable amino acids.
It is rapidly absorbed by plants, resulting in better growth, healthier plants, bigger flowers and more fruit.
OCP eco-aminogro is perfect for use on veggies, flowers, natives and pretty much everything else.

eco-aminogrow  is available from hardware stores, nurseries, supermarkets and online »

Vegetable caterpillars are easy to control

The sudden appearance of smooth-edged holes (ranging from very small to quite large) in recently established leafy vegetables, particularly cabbages and broccoli, is a good indicator of caterpillar damage. 
Caterpillars are very easily controlled by spraying plants with Spinosad Ultra – a non-toxic chemical that stops the caterpillars from feeding (immediately) without affecting other insects or wildlife.

Ideal conditions for powdery mildew

Cool, moist nights followed by mild to warm days provide ideal conditions for the fungus disease, powdery mildew.
This fungus can quickly devastate plants that are not growing vigorously.
Vegetables, such as tomatoes, zucchinis and cucumbers are very prone to attack, particularly as they reach the end of their life.
Roses, grape vines and crepe myrtle are also very susceptible.
Try spraying with eco-fungicide or milk (1 part milk to 10 parts water).

New geraniums grow readily from cuttings            

Early autumn is a good time to strike cuttings from those new high performing "Big" geraniums. 
Take tip cuttings 6-8cm long, place in moist (not wet) coarse washed sand and locate in a shaded, protected position.
Keep the propagating material on the dry side.
Rooted cuttings should be ready for potting on early in spring.
Other plants that grow readily from autumn cuttings include coleus, begonias, fuchsias, grevilleas and correas.

The importance of fertilising lawns in autumn

Tradition says you should fertilise your lawn in autumn. But why is this so important?
Conditions in the garden during autumn, particularly the weather, vary from one season to the next.
So how do you manage to get the timing right?
In this week’s lawn blog turf consultant Stefan Palm not only considers the importance of fertilising your lawn in autumn, he also explains what you should look for in a typical lawn fertiliser
