Are you ready for winter?

It may be cold and sometimes wet but for the next 10 to 12 weeks trees and shrubs that are deciduous will also remain  dormant.
During this period they can be planted, pruned or even moved without a setback before bouncing back into life early in spring.
Give high priority to hydrangeas, fuchsias and roses, as they will start making new leaf growth by the middle of August.
Deciduous creepers and vines should follow, then ornamental trees, fruiting stone fruits and finally apples and pears.

No need to rush – but consider where you'll plant

While it will be a week or so before garden centres are stocked with a full range of deciduous plants, take the opportunity of checking out potential planting sites. 
Most trees and shrubs dislike soils that drain poorly. 
Clay soils can be improved considerably by spreading gypsum over the surface (one kilogram per square metre). 
Alternatively, you can plant into a raised garden bed or into large containers.
Wagners roses for special occasions

Some roses are extra special

There is something unique about roses for special occasions and roses with special meaning.
At Wagner’s Rose Nursery – one of Australia’s largest – there is now a new online catalogue to help you with your selections of roses for that special occasion.
Wagner’s, based at Kalangadoo in SA's South East, specialises in providing new-season roses and selling direct online.

Here's two of their special roses:

Coprosma Pacific Sunrise (left) and Pacific Sunset.

Year-round colour from Pacific Coprosmas

When the colour from most flowering plants has faded, there will still be stunning foliage plants such as the Pacific Coprosmas.
Pacific Coprosma Sunrise and Pacific Coprosma Sunset are real showstoppers, producing attractive 1 m mounds of glossy, wave-shaped leaves.
Sunrise leaves are chocolate brown with hot pink highlights while Sunset features a vivid red centre set against burgundy to chocolate brown margins.
Pacific Coprosmas are incredibly tough and once established need very little maintenance.
They are great for hedging, edging, topiary or simply growing as feature plants in the garden.

Paciific Coprosmas are in stock at Heynes Garden Centre, Norwood and should be available at other good gardening centres.

These Bacopas are better

Bacopas are one of the latest perennial plants to really benefit from a breeding makeover.
The latest Elite Bacopas produce masses of delightful, five petal flowers on cascading stems.
However, they remain in bloom much longer than other varieties.
This display begins early in spring, pauses a little over summer and then continues through autumn and well into winter.
Elite Bacopas are quite compact, only 20 to 30 cm high, while spreading 60 to 90 cm wide.
This makes them ideal for container growing and planter boxes.
They also look stunning as a flowering border.
Plants carrying the Elite label have been selected for their reliable flowering, large blooms and ability to flower early.

Bacopas are in stock at Heynes Garden Centre, Norwood and should be available at other good gardening centres.

Making your own compost

If you are a keen gardener it's worth making compost in a proper compost bin. 
Large green polythene bins are available commercially.
The most useful have a clip-on lid at the top, while the base is open and placed directly onto the soil. 
The clip-on lid allows you to add new material and when sealed, the smells are kept in while the rodents and flies are kept out. 
Once the bin is full allow 12 to 14 weeks for the material to decompose.

Bins that rotate

Rotating bins are more expensive, as they feature a large cylindrical bin (with an access lid).
During winter these should be rotated weekly.
Rotating mixes the materials inside and more importantly provides an adequate source of oxygen. 
If the materials you supply are moist (but not soggy), it is possible to produce good compost in six to eight weeks.

    Getting ready for a wet winter    
Are your container plants drowning in drainage?    

Most plant containers are filled with potting mix that drains freely.
As a result, any surplus water should disappear quickly through the drainage holes at the base of the container.
However, over time these holes can become blocked (plant roots, fine sand, accumulated organic material, etc).
Drainage problems during a wet winter, when there is little growth or evaporation, is likely to result in a build up of water within the container.
In essence the plants virtually drown in their own drainage.
Where possible push the containers on their side and use a strong thin screwdriver to unblock the holes. Make a note to repot the affected plants in spring.

Wet weekend – check your garden tools

It looks like we are in for a wet weekend – an ideal time to clean out the garden shed and check on your supplies of fertilisers and chemicals.
Maybe, buy a file and sharpen your secateurs, spade and hoe. You could be surprised you how much difference this makes.

Plums – the home garden all-rounders

In SA home gardens, plums remain at the top of the popularity list.
And why not? They are certainly reliable, hardy, easy to grow and adapt readily to our garden soils and summer climate.
However, they are also packed with flavour, making them great to eat fresh, stewed or used as a health juice.
Santa Rosa (pictured) is a gorgeous medium-sized round plum with sweet juicy yellow flesh.
Satsuma remains popular with home gardeners as it is a prolific bearer and produces medium round purple/red fruits with red flesh.
Ruby Blood is a great late-season performer and for a health kick try the A Okay plum with its extremely high levels of antioxidants.

Weeds taking off despite low soil temperatures

It may be cold but weed germination over the past three to four weeks has been prolific.
Weeds in paths and open spaces are an emerging problem, even though Adelaide topsoil temperatures have been around 11 to12°C.
But they are very easily controlled by zapping them (while they are small) with an all-purpose herbicide. 
A 500ml trigger pack, ready-mixed, should solve most problems.

Caterpillars best hit with a non-toxic spray

Check the vegetable patch for signs of caterpillars on cabbage, cauliflower, broccoli and sprouts. 
If there are only a few insects, remove them by hand.
But if spraying is warranted use a non-toxic spray, such as Success or Dipel.
broadleaf weeds

Finding the right weed control solution

Removing broadleaf weeds from lawn grass using a selective herbicide is quite easy.
Most garden centres and particularly lawn specialists now offer a wide range of selective herbicides along with sound “how to use “advise.
Selective herbicides are designed to remove the broadleaf weeds without harming lawn grasses (couch, kikuyu and buffalo).
According to turf consultant Stefan Palm most selective broadleaf herbicides contain the active ingredient MCPA.bin-die selective lawn weed killer
Many also contain bromoxynil or dicamba.
These are both selective but more active against some of the harder-to-control broadleaf weeds, particularly creeping oxalis.
Products containing bromoxynil, such as Amgrow Bin-Die kill virtually all broadleaf weeds but will not harm the roots of nearby trees and shrubs – unlike some products that are added to MCPA.

Not fairy rings, simply fungus

Mushroom and toadstool-like growths that appear in the garden, particularly lawns at this time of the year are in fact the reproductive forms of a fungus that helps break down organic matter in the soil.
Causes include decaying roots of trees or shrubs and often, decomposing thatch from couch, buffalo or kikuyu lawns. 
If they worry you, simply scrape them away and place in the green recycling bin

Early fruit drop hits heavy navel orange crops       

Many home gardeners are looking forward to a heavy crop of navel oranges. 
However, premature fruit drop is causing considerable concern. 
In most gardens, this is linked to a hormone imbalance within the tree, associated with the heavy crop. 
There is little you can do right now to prevent the problem. 
In the long term, make sure the tree receives a regular supply of balanced fertiliser i.e. nitrogen, phosphorus and potash. 
If you hold near-mature windfalls for a week, the fruit acid will drop a little and they should be suitable for juicing.
