I am concerned that the mustard I planted in October 2011 wont be ready for planting if I put the manure now.
Do I need cardboard and the manure, this area of my plot is clear of bindweed?
What depth of manure do I need for the mustard to die?
Should I chop up the green manure before I cover it with horse manure. and finally when is the earliest I could plant anything in this area.
