Meet the Zingiberales

Every gardener is familiar with some members of the Zingiberales, you’re likely to find examples of six of these families in every street and garden centre in Queensland. You may even know their families are related. Plant a few and your garden can have its own source of attractively shaped, delightfully coloured and sometimes fragrant cut flowers and foliage.

Glyphosate: War of the Weedkiller?

Tropical Crops For Summer In Northern Australia

I’ve been surprised to get messages from gardeners in far northern Queensland saying “we can’t grow many crops in summer,” and “summer isn’t a good time for leafy crops,” and “the best season for growing food here is winter.” Why so? The tropics are incredibly productive all year round and their abundant produce is in such demand. There’s at least fifty different leaf crops, so let’s have a look at what you could be growing.

Home Grown Food Security: Jackfruit.

Jackfruit (Artocarpus heterophyllus) excels in a tropical or subtropical climate. It’s food security on a stick. They produce edible, protein-rich seed and fruit which can be used and stored in many ways and at different stages of ripeness. This year, my seven year old tree is carrying 150 fruit, which is about average. Don’t ask…

Brisbane Skips Winter. Again. What To Sow Now In The Subtropics?

In the last week of July, my garden was behaving as if it was already spring. Five weeks early. Four chilly blasts, each lasting for two or three days, seems to be all we need to anticipate in a 21st century Brisbane subtropical winter. Of course, there are winners and losers. Fruit fly is a winner; my first tomato to be damaged by their maggots was on 1.8.20, almost eight weeks earlier than anticipated. Alleged subtropical apples are losers; while these cultivars may tolerate less winter chilling than other apple cultivars, their needs are not being met and the return is poor. But corn is a different story – it is a climate change winner.

The Mary River Turtle: Uniquely Australian, Ancient and Endangered.

The Mary River freshwater turtle (Elusor macrurus) is one of the most uniquely Australian and critically endangered turtles, living only in south east Queensland’s Mary River. Forty years ago, Mary River turtles were sold as ‘penny turtles’ through the pet trade, hatching just in time for Christmas. Twenty six years ago, this turtle was finally scientifically described. Ten years ago, the Australian government ruled against the Queensland government proposal to dam the river, which would have exterminated this species. Now, Queensland’s Tiaro and District Landcare volunteers monitor Mary River turtle nest sites, protecting them from extreme weather and predation, while the Mary River catchment group look after the health of the river system, the only home that this endangered turtle has, giving it a better chance of survival.

FAQ: Can I Grow Plants In Polystyrene (Styrofoam) Boxes? Someone Told Me They Are Toxic.

This blog looks at ways to convert expanded polystyrene foam boxes, a single use plastic used for packing vegetables, into a useful gardening asset. Most Australians call expanded polystyrene foam styrofoam, but this is a trademark name, owned by Dow Chemicals, who claim to have ‘discovered’ this product which was first made in Sweden. If you endorse the reuse of waste, visit your local fruit shop and get some polystyrene vegetable packing boxes. Retailers are happy to sell them for a couple of dollars and you’ll find them suitable for a range of gardening jobs whether your climate is hot, cold, wet or dry.
