21. Weeds

Weeding is considerably reduced by zero tillage, mulching and intensity of care. The fact that the soil is not turned between crops also prevents buried seeds from rising. When rotations [immediately] follow one another, the soil is weeded frequently and this task reduces as the weed seed stock runs out.

Good weed management is to be taken seriously because invaded growing beds lose a lot of productivity. Weeds can be mulched onto the beds when they are young (a nitrogen source), but we must be careful not to let them go to seed.
