This garden is a microcosm experiment to practice organic gardening and soil sustainability so I'll be posting updates and results often for feedback and discussion.
The plot was handed over to me already weeded and the topsoil was already loosened by the previous owner, so I didn't need to start from scratch like my last one. I'm using the French Biointensive method as a guideline which recommends double digging raised beds; ie-dig a spade's depth and remove dirt, then loosen a pitchfork's depth under that, followed by moving a shovel's depth from the next trench on top of the loosened first and continuing on until the plot is done. Of course a soil analysis is recommended to adjust nitrogen, potash and phospherous and check the Ph level, but I may opt to just add plentyof fresh compost, which balances out those things and use gardener's intuition instead.
Progress so far:
Feb 11: Double dug 1/2 the plot (100 sq ft) and added 4.5 cu ft organic compost to top 8 inches. Removed large rocks and soil clods, as well as much sweet potato roots. Topsoil is a loam with subsoil a clay loam characteristic of tropical regions. I watered down the bed (excellent drainage due to the double-dig)and let it rest for 2 days. There were MANY healthy earthworms present in the clay loam which is very encouraging.
I also salvaged a lot of wood and particle board nearby for the toolbox and bed liners which I was planning on using, but parhaps I may go a simpler, more natural route instead. I'll have to see what the availability is on dead tree limbs and stones before making a decision on that. I like the idea of using only salvaged materials but the natural look and handcrafted approach might be more rewarding. I have a bunch of used wine crates as well, that might add something to it. I hope to finish double digging and soil enrichment this week and start on the bed liners, access path, tool box and trellises.
