Talkback: Rich pickings
Hi, I myself was a new allotment gardener last year, and I would agree with all the advice given, but I would advise against a rotavator. I found when I used one on one bed weeds like dock and buttercup have been coming up everywhere! As you know these are much more difficult to dig up and eradicate, and it appears that the rotavating cut them up into tiny pieces that all sprouted.
My advice would be to just dig it over and cover until next spring, if you break the beds into reachable widths, say 2-3foot across weeding will be easier! Good luck with it all, it has changed my life!
