| | | | | COOL - Cool temperate gardeners, as your growing really gets going, it’s a great idea to check grafted plants and snip off unnecessary growth and sprouts from below grafts before they take over.
- Green, mean and often unseen, the caterpillars of the Cabbage White Butterflies are wreaking havoc on brassicas now. The best method of control – pick and flick the caterpillars and feed them to the birds
- Coming into bloom now is the Victorian Christmas Bush, Prostanthera lasianthos. This native shrub has menthol-scented foliage, masses of minty flowers, and is a stunner in a shady spot.
TEMPERATE - In warm temperate gardens, rosemary can be pruned back to minimise disease caused by hot, humid weather. Cuttings can be propagated or donated to the local RSL for Remembrance Day.
- Keep an eye out for the stunning metre tall, leafless stems and fabulous flowers of the native Pink Hyacinth Orchid, Dipodium roseum, putting on a show in native woodland at the moment.
- If your roses have finished their super summer show, it’s time to prune them back and deadhead. Follow up with a feed, and this will ensure a good repeat flowering come Autumn.
SUBTROPICAL - It’s hot hot hot in the subtropics right now, so make sure you harvest your fruit, vegies and herbs in the morning before the heat knocks your crops for six during the day.
- Melaleucas, callistemon and other woody natives are susceptible to the wicked webbing caterpillar over summer. If you notice clumps of webs in foliage, cut out and bag up for the bin.
- If cane toads have you jumping, get involved in the University of QLD Cane Toad Challenge citizen science project, testing toad poison and tadpole traps. Details on our website.
TROPICAL - Tropical gardeners, if you’ve noticed small holes in trunks and sawdust around your acacias, you may have borers. Grab a piece of wire and poke into the holes to stop them in their tracks!
- Tip prune and tidy passionfruit, this will promote fab flowers, and flavourful fruits that form on new growth.
- Give your plants the best chance of fighting of pests, and dust garden beds with garden lime monthly. This is a great way to increase the health and vitality of your favourite foliage.
ARID - Gardeners in arid zones, attend to fruiting and flowering plants and prune to remove unwanted seedpods. This helps the plant put its precious energy where it’s needed – roots and shoots!
- Have a ‘swale’ of a time this weekend and set up some simple soil swales to direct your precious water to plant roots and soak in rather than run off. Topping up mulch can also assist.
- If you have a patch of the plot not yet planted, why not whack in some sweet corn? These gorgeous grasses are wind-pollinated, so plant in a block, with about 30cm between each stalk
