Edible Forest Gardens: Vol 2. Chapter 5 -- Site Preparation

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.
