I have just received a load of well-rotten horse manure, but already have mature green manure growing. What do I do–cut and compost the green manure and then add the horse manure on top? Or cut, fork in the green manure and then add the horse manure on top?
Or just leave the green manure until about 4 weeks before planting something there, then cut and fork it in to rot and do not put on the horse manure?
Reading the various web pages on green manure does not give clear advice on this.
Am interested that Pete Budd did not fork in his green manure–rather composted it. Is this because ‘forking in’ is digging and therefore disturbs the soil structure?
