Nanny’s Cabbage Companion Confirmed Caterpillar Killer By University Of Queensland

In London in 1975, my maternal grandmother, Dorothy Connor, had her best ever crop of cabbages, despite record-breaking drought. That year, she had grown landcress (Barbarea vulgaris) amongst her brassicas. Decades later, Nan’s recommendation to grow landcress with brassicas has been backed by scientific research at the University of Queensland. She would have been tickled…

Organic Win: Nematodes Defeated In Wynnum

Root knot nematodes can be a curse in warm, moist garden soils. Feeding by these minuscule, transparent, work-like creatures inside the root tissue of many crops causes the roots to develop tumour-like growths which retard the flow of water and nutrients through conducting vessels, weakening crops. What to do?

Success With Pumpkin In The Subtropics

Question: When do I sow pumpkin? I read in gardening magazines pumpkin can be sown from spring to autumn in the subtropics. But advice on seed packets (and some magazines) suggest that pumpkin should only be sown from spring to summer. I have a garden at Camp Mountain 4520 where we do not get frost, please…

In Production Today: October 2014

Brisbane’s warm, dry, breezy inter-season, sprummer, (the period between spring and summer) is intensifying, hastening the production of seed from winter crops. The seed of Ethiopian cabbage (Brassica carinata), Chinese cabbage ‘Tokyo Bekana‘, mizuna, flowering turnip (aka rapini, Brassica rapa var rapa ‘Cima di Rapa Quarantina’) and mustard ‘Osaka Purple’ have already been harvested.

Hippeastrum: Somewhere Over The Rainbow

If ever there was a plant perfectly suited to the sets of the Wizard of Oz, it’s Hippeastrum. These flamboyant flowers are dead easy to grow and Australia is fortunate to have the likes of Mick Maguire, a dedicated hybridist and grower.

Paddy to Plate: Gardeners and Gourmets To Tour Vietnam, 2015

There is so much to learn about growing and preparing tropical food plants. What fascinates me is that many of the fruits, vegetables, herbs and spices growing in south east Asian food gardens also have medicinal purposes. Enter kakrol, a fruit somewhat resembling a startled pufferfish…

Surprisingly Nutritious Vegetable Damper Recipe

This damper recipe includes green pawpaw (Carica papaya) and Warrigal greens (Tetragonia tetragonioides), which are currently abundant in my garden. Both are self-sown crops. Served either as damper or used as a pizza base, this simple dish is surprisingly nutritious, especially if you use wholemeal flour. Please observe the kitchen chemistry notes.

Community Rose Garden Brightens North Burnett

Just under 700 people call Biggenden home. In 1954 this country town, in Queensland’s North Burnett region, 339 km north of Brisbane, established a community rose garden along its main street. It became a symbol of civic pride. Roses do not live forever, and eventually the rose garden needed refurbishing. I was contacted by Council, and…

In Production Today, September 2014

Spring is over in my garden. Winter crops are flowering – my garden is transitioning into its seed saving phase.

Father’s Day 2014: Concerning Seaweed And Quadratic Equations

This is a fictional letter. My father, John, who had been living for some years with Alzheimer’s, died shortly after I emigrated to Australia. My sister and I looked after Dad at home for several years until he required full time professional care. During the period when his mind was failing, remembering our family and things…

Petal Power: Edible Flowers

Edible flowers have a long history of being grown for making dyes for food and fabrics, or as decorations for cakes, salads and garnishes. What’s surprising is how many commonly grown flowers are edible.

Hedge on the Edge: Is This The Ultimate Hibiscus?

I have been instructed by Denise Horchner of the Perennial Poppies Garden Club to write about my Phillip Island Hibiscus, Hibiscus insularis. This Australian species could be described as the ultimate hibiscus. As far as I’m aware, I’m the only person who uses this critically endangered wildflower as a flowering hedge. Planted to welcome visitors and to shelter my front garden from desiccating wind, birds and people love its blooms. I make jam and a soothing tea from a species that has become my signature plant.
