Want A Rainforest Garden? Then Plant Dry, Not Wet…
Once established, dry rainforest species survive longer, hotter, drier spells and erratic rainfall better than wet rainforest.
Succulents: Chlorophyll With Character
My first flower memory is of a cactus. I was about three years old and peering up into a huge, red Epiphyllum flower. It sprouted from an old, much-loved plant belonging to my Grandmother. My sister still grows a cutting from the plant Nan acquired during the Great Depression (around 1929). It’s been in my…
Hibiscus Leaves Helped Save Australian Lives
I’ve just found a letter written years ago in response to an article I wrote about edible members of the Hibiscus family (the Malvaceae). This refers to rosella leaves (Hibiscus sabdariffa), an icon of Australian backyards, and also peasant food or famine food in Bangladesh, Thailand and Burma. Rosella leaves helped Australian prisoners survive the…
Freedom 2014

Thrifty, Fertile and Illicit: 4BC Horticultural Intervention
So there I was with Noel Burdette, in the pre-dawn darkness of Brisbane’s Cannon Hill. Groggy but organised, and with only a smartly dressed security guard as a witness, we got stuck in.

In Production Today, March 2014
The most widespread recorded drought in Queensland’s history has meant most of my gardening effort continues to be spent on watering and soil improvement. At least I’m able to keep fruit trees productive and perennials alive. Beds which would normally be filled with seasonal annuals can remain dug, mulched and bare until useful rain arrives. But…
Dry soil after the storm
After the storms that hit Brisbane yesterday you might expect that I could give watering a rest for a while.
Citrus: Avoiding The ‘Danger Zone’ To Achieve Abundance
Trish & Malcolm have finally solved their citrus fruit drop problem. Autumn is an important season for citrus maintenance, especially if they’re growing in areas with summer rainfall. This is because heavy rainfall leaches nutrients through the soil and citrus are really quick to show they’ve got deficiencies. For a quick nutrient fix: To four…

Review ‘Eat Your Garden’, By Leonie Shanahan
Review: ‘Eat your garden’, by Leonie Shanahan; Publisher: PI Productions Photography; ISBN 9780975217764; 2010. “If they (children) grow it, they will eat it”. Schools are where Australia’s gardening culture is most rapidly developing, and this is thanks to children. Why? They are generally more keenly aware of 21st century global environmental issues than many adults…
