Today we had a fantastic session with Keith Colls, President of the Canberra Organic Growers’ Society. They have a great new website with heaps of helpful local information.
COGS has been running for 30+ years, and runs meetings, workshops, courses, a magazine and 11 community garden plots around Canberra. The organisation focuses on food growing using organic methods.
Keith talked about the organic approach which doesn’t just mean an absence of chemicals, but really revolves around considering the garden as a biological whole, and feeding and nurturing the soil.
He recommended some good books for local gardeners:
- all available at local bookshops.
Starting your own garden
Kevin recommends digging a few holes around the garden and have a look at the composition and layers of the earth. Check TEXTURE and STRUCTURE. Adding organic material (anything that used to be alive) will improve the soil.
Then make some compost, most simply by throwing together a big pile. All compost piles will eventually break down into lovely compost, but it might take a long time if you use a very low-key approach. To speed things up, you can make a pile with a layer of heavy branches, etc at the bottom to let it air, then alternating layers of green material (kitchen clippings, etc) to leaves/straw. There should be about 3 or 4 times as much bulky material as green material, and you can throw some chook or horse poo or old compost in between the layers to speed things up.
Water
Kevin brought along some equipment you can use to make a simple dripper system. He suggests going to an irrigation place rather than a hardware store as it might be a bit cheaper. (Member Kirsten has just set up her garden and found Reece Plumbing in Mitchell really helpful).
Kevin warned that it’s not wise to use greywater directly on plants without being very careful about any detergents in the water, as excessive salt or trace elements can cause terrible soil problems. He recommended checking the Lanfax Labs site (who test for Choice magazine),
although he cautioned that he was more careful of trace element boron in detergent than they recommended. His choice was on the basis of information in the Handreck book noted above – and he noted that it’s one of the frustrations of a beginning gardener that books have so much contradictory information!
A final tip was that the regular COGS meetings, and CIT Horticulture students both offer a pest/problem identification service. CIT won’t give you an organic solution, but you can’t do anything without knowing what the problem is.
There will be one in Dickson at the end of this month – check the “Upcoming Events” on the COGS site for details.
Keith’s attitude was lovely – often things will just work, and if they don’t try it a different way next time. And don’t be too tidy!
