After resuming my reading in Edible Forest Gardens, I picked out some techniques that seem promising for site preparation:
- Rock dust
- Cover Crops
- Mulch -- 1/2 - 4 inches. Not next to woody trunks.
- Torching weeds
- Infiltration Swales
- Double Digging
- Radial Trenching -- sort of like double digging for trees (figure 5.10, p. 361)
- Mounds -- but need to consider the impact of soil texture transition
I found the last line of the chapter to be telling:
One thing is true, though. If you skip site preparation, you are likely to regret it for a long time to come.
