Queensland Cucumber Mosaic Virus Alert

Cucumber mosaic virus is a threat to food security. Last year this highly destructive disease was identified on a farm near Bundaberg, and now it has been found on a Charters Towers watermelon farm. As a student at Kew Gardens, this was a case study, and we were drilled about implementing ‘on site’ quarantine procedures to…

In Production Today, April 2015

Here’s my subtropical food garden’s current autumn menu. Plants marked with an asterisk are volunteers, that is they are self-sown. Currently I have 38 different volunteer crops.

Living With Mosquitoes In The Subtropics

Question: “Hey Jerry, we’ve found mosquitoes to be a real problem for us on the northside this year. An electronic device has been recommended, do you have any views on it?” Barnaby via Facebook Reply: Hi Barnaby, I had to adapt to living with mosquitoes when I moved to the subtropics from warm temperate Sydney in 2003. I’ve…

How Can ‘Dog’s Vomit’ Have A ‘Hive’ Mind? Enter The Kingdom Of The Slime Moulds

“Truly alien creatures…are all around us” Professor Christopher Reid, University of Sydney At dawn you could mistake them for vomited curry, something people find disturbing. They surface during the night, forming moist, sulphur-yellow pools and then tiny stalagmites emerge from them, forming miniature landscapes. As the sizzling Brisbane sun rises their colour quickly fades to…

Cyclone Near Miss And Food Production, February 2015

As Cyclone Marcia gets downgraded to a Tropical Low weather system, my soil and crops have had a good soaking: 236mm in the past 48 hours. No crop losses so far – 106 different edibles available. Lucky conditions for my ‘Red Aztec’ corn and Jerusalem artichoke ‘Dwarf Sunray’, they’re just days from harvest.

Bunya: Prehistoric Plant, Ancient Australian Food Tradition

“Young Australians need to be educated about what a Bunya tree looks like, what the sound of snapping cones and breaking branches sound like, and to avoid lingering underneath them in high summer. When I was at primary school, we had a Bunya in the schoolyard. We knew what to do, how to harvest them, and no one was ever hurt.”

In Production Today, January 2015

Here’s my subtropical food garden’s current summer menu of 107 different kinds of root, shoot, leaf, petal, seed and fruit.

Rarity Is Commoner Than You Think

I own a critically endangered plant. It comes from Madagascar, an island degraded by human activity and peppered with endangered species. When I discovered the news that my Gerold’s Thornless Crown of Thorns was on the brink of extinction, I had a flashback to planning the Rare & Endangered Plants Garden for the Royal Botanic…

Turmeric In The Garden And Kitchen

Turmeric (Curcuma longa) is indispensable in the kitchen and easily grown in a frost free climate. The tasty leaves and rhizomes and edible flowers are useful for flavouring and colouring food. In some countries, turmeric is used to help manage post traumatic stress disorder. After gardening in the heat and humidity of a Brisbane summer’s day, I find turmeric tea, a Javanese speciality, very refreshing. Some years ago, an Indonesian friend said “Drinking turmeric daily reduces body odour, helps keep you healthy and may prevent cancer”. Another favourite use I have for turmeric is making sfouf, aka turmeric cake, a delicious Middle Eastern recipe.

Why Does The Label Say My Ornamental Chilli Is Toxic?

Question: Yesterday a caller to 4BC Radio’s ‘Talking Gardening’ programme asked why the label on their ornamental chilli plant called it Capsicum annuum, and also said that it was “Unfit for Human Consumption”?

Mangelwurzel Harvest

I imagine everyone is outdoors, harvesting their mangelwurzels (Beta vulgaris subsp. maritima) today like me. A friend is thinking about brewing mangelwurzel beer, they’re supposed to make a potent drop. Alcohol is not my strong point. Would a beetroot or turnip recipe work as a substitute? Can anyone point me to a recipe?

Chilli Jam

What do you do with an embarrassment of chillies? Normally, I deep freeze chillies and keep a year’s supply to hand. But when I picked 500g of ‘Piri Piri’ chillies from a single plant, I had to change my plan. ‘Piri Piri’ is a chilli which originated in Portugal and was introduced into South Asia…
