Square Foot Gardening
In reply to Mike Gordon at 2:03 pm on Friday 23 January 2009, who wished to know about Mel Bartholomew entitled Square Foot Gardening. Yes I am seriously working this method including his special mix (one third each of good compost, peat and vermiculite and then everything goes into marked one foot squares). Two years and the results are extraordinary. No disease, nice plant size, slugs and snails hate vermiculite (the big ones). Just make sure you use chicken manure at double the recommended rate when topping up. The only real failure is onions, but then I never have been able to grow them anyways. Recommend 8/9 inches of mix. Avoid introducing earth, so clean compost. Line sides and base with terram, otherwise you will get leaching back of soil and pests, or possibly any nasties in wood surrounds. So far have 192 square feet, and plan to double. Framework 6insX2ins pine rafters, most economic 4.4metres which gives you 3 4Xft blocks joined. Stack one plank on top of another to give 12 ins depth. Use 8/9 ins mix only. Securely bolt corners using 2X2ins wood, about 2 metres high which will hold pea or beans with transom between. Then normal canes or netting. Do not use screws or coach bolts, as they do not last. Ends same wood, then two partitions walls can be any old rubbish wood, as not load bearing. Structure should last 10 years plus. Best vermiculite is V4 from local builders merchant. Sphagnum Irish is much better than Garden Peat. Good luck.
