The previous plot owner to my new allotment sowed perrennial Rye Grass - they tell me it was because he was "turfed off" and he did it to be vindictive! I think it may have been just to let the ground lie fallow and he was helping to lock nutrients in and keep other weeds out.
The problem is I have the legacy of a rough lawn to get rid of.
Considering it is approaching Autumn now, am I best to not bother digging, but lay a carpet of newspaper, then corrugated cardboard, then black plastic and lift it off next spring and let the worms do the job for me?
Another suggestion from a seasoned gardener was to double dig the whole plot and invert the turves. They will then die and feed the soil.
However, there may be just enough bare soil areas on the plot to get a few catch crops in before end of seeding season and just leave the grassy areas under a light excluding cover.
Why be digging when I could be building a shed and sowing a few seeds at this late stage?
The allotment is about 5minutes away so I could spend up to an hour every free evening.
