Hello, yes I have done most of it and the reason I want to green manure/cover the remaining 1/3 is that this is my first year - (actually my first month!) and I dont want to go steaming ahead and do the whole plot in case I cannot mantain its upkeep.
I thought the first 2/3 (it is a full 10 rod plot) would be enough for me to see if the one hour three times a week plus weekends that I have spare is enough to keep it up, I can't see the point in blindly digging the whole plot if 6 months down the road I can't keep on top of the weeding, etc! I have PSB, onions, peas, garlic in already and pots are chitting, and all manner of yummies are in the greenhouse so I am certainly intending to grow lots and nowhere near fed up - far from it! Thanks for the advice people! ;)
