The take-away container propagation method. Place cleaned seed on a damp cloth, replace lid, and leave in a warm place.

The feijoa (Acca sellowiana, aka. Feijoa sellowiana) is one of those underrated suburban fruit trees that is often (perhaps unwittingly) grown around Adelaide backyards and little eaten. The varieties I’ve come across most often have offered grey-green torpedoes with a sharp, pineapple tang and a somewhat gritty texture. In the height of feijoa season, we were given a paper bag full of a variety I’d not encountered before. The skin was thin enough to bite a chunk out of and the flesh silky(ish) and smooth.

Farm Hack: Nursery tables

nurserytableOur passion for growing trees has in many ways outstripped our capacity to grow them, and so our growing space has become overrun with foam containers balancing precariously on the edges of hard rubbish chairs, bricks and scraps of wood. Some months ago, we claimed some old school tables from a local school’s throw-out pile, and thought they might be good for more growing space. Predictably, the manufactured timber tops very quickly fattened in the moisture, buckled and then started getting slimy.

If a tree falls…

IMG_3799A couple of months after the central third of our biggest remnant red gum crashed to earth, I climbed into the centre of the fallen limbs to try to remove some timber for erosion control structures. I was surrounded by the faint, constant pattering of distant rain. The tree was rustling, but no wind moved the leaves. I put my ear to the boughs and realised the sound was coming from inside, exhaling as the timber dried and cracks slowly opened in the bark. Meanwhile, in the leaf litter below, the spiders and beetles delight in the thick undergrowth of their new canopy. Continue reading →

A One-Page Place Assessment for TBC Farm, Second Valley

Brad Lancaster’s books on Rainwater Harvesting would have to be among the most consistently inspiring books we own. Two volumes into his trilogy on Rainwater Harvesting for Drylands and Beyond, Lancaster combines accumulated community wisdom with permaculture principles to produce lavishly illustrated, practical and highly accessible manuals for managing water in urban and rural environments. Consistent with permaculture thinking, Lancaster urges land managers to spend time observing the season patterns of the landscape to more effectively design for sustainable, integrated water management. One method of doing this is to compile a One Page Place Assessment, drawing together essential climatic and ecological information about your particular location.

Our first year has been one of spreadsheets, mapping out our seasonal observations and activities, and the One Page Place Assessment concept is a elegant way of compiling climatic data from Second Valley and the surrounding area. We’ve finally completed the first version of a place assessment for our property, with much of the data drawn from Bureau of Meteorology stations nearby (Myponga Reservoir being the furthest). While we have tailored information to our particular location, we hope it will be of use to other landowners in the region. We have also referenced information sources so others can draw on the same resources in exploring their own area.

Book Review: Embracing an arid future in “Growing Food in a Hotter, Drier Land”

Years before there was talk of locavores and 100-mile-diets and omnivore’s dilemmas, I came upon Gary Nabhan’s book Coming Home to Eat, a personal account of his experiences striving to solely eat food produced in his home bioregion of the US-Mexican borderlands in southern Arizona. His observations as renowned desert ecologist and ethno-botanist redefined how I thought about food and sustainability and accompanied me on my own sustainable food explorations for years after.

I get the feeling that his latest book, Growing Food in a Hotter, Drier Land: Lessons from Desert Farmers on Adapting to Climate Uncertainty (Chelsea Green, 2013), may be another companion for us in our adventures on the farm. While Growing Food is as practical as its title suggests, it is permeated by Nabhan’s respect for the insights of cultures deeply connected to the land, and his belief that communities connected to their bioregion are the most resilient in the face of environmental change.

Travels in Inter-Tussock Space: Planning for Woodland

We’ve seeded our last 150 tubes in preparation for planting in a few months time. When the rains come, we’ll have over 1000 plants ready to go. Most are destined for the regeneration areas we’ve fenced around the waterways, but a few others are non-indigenous livestock fodder plants, timber trees and food plants we’ve raised from seed and cuttings to begin developing other zones around the farm.

It’s a Pink Gum Woodland, it just doesn’t know it yet.

Late in 2013, along with a posy of other plant nerds, we attended a workshop with botanist Ann Prescott (author of It’s Blue with Five Petals) to explore ideas behind revegetation for habitat. We walked through remnant woodland in the hills above Yankalilla, and tried to imagine how our farm might have looked 180 years ago. Continue reading →

IMG_3630River red gums (Eucalyptus camaldulensis) are notorious limb droppers. With the recent blistering temperatures (Adelaide’s been experiencing been experiencing strings of days above 40 degrees Celcius, and the normally milder Southern Fleurieu has had days in the early 40s) and a burst of gale-force winds, one of our two remnant red gums has lived up to its notoriety.

While our impact on this landscape has been pretty minimal so far, with the completion of our first phase of fencing, we’ve begun more major infrastructure works. We’ve started by fencing off two big chunks of ground encircling the erosion gullies, surrounding them with a roughly 20-metre buffer zone for future woodland regeneration.

Neat knots

In a permaculture sense, these patches of ground will be our Zone 5, our minimal-management ‘wilderness’ zones, designed for habitat and ecosystem services such as erosion and salinity control and water filtration. Abutting our western boundary they form a link with the creeks and swamps that feed the Congeratinga River. With these zones now marked onto the landscape we can plan outwards towards zones of increasing management intensity. Continue reading →

DPP_0004_2When we first dug the post holes for the bee house, it was winter. It was a clear, sunny day, but only 30cm underground it was a river. Now, the soil has hardened again and already cracks are forming where the sun has touched between the tussocks. It is the time of insects: the long grass shimmers with the darting of grasshoppers and butterflies, the red gums are awash with ants and centipedes uncurl in dark, hidden places. It’s a good time to introduce our first livestock – bees – and to finally complete their shelter: the Bee House. Continue reading →

Learning the land with ‘The Biggest Estate on Earth’

In The Biggest Estate on Earth (Allen & Unwin, 2011), historian Bill Gammage describes a detailed vision of Aboriginal land management prior to European colonisation of Australia. While many Australians have a broad sense that “fire-stick farming” was (and is) a tool used by Aboriginal people, The Biggest Estate on Earth begins to fathom how finely tuned Aboriginal fire use was. With fire as one of a suite of tools, Aboriginal people across the Australian continent carved the landscape into a mosaic of ecosystems, each harbouring plants and animals of differing sensitivity to fire, each maintained to maximise ecological diversity and each nested within the other to increase the ease of hunting or harvesting. For Gammage, Aboriginal land management across the continent was directed by three main principles: “ensure that all life flourishes; make plants and animals abundant, convenient and predictable”; and to “think universal, act local”.
