Anyway, Stu and I decided we just had to go for it. We went up to the allotment and took the plastic sheeting off a patch of earth. We dug over the top layer and pulled out the couch grass and raked and levelled and then planted the little seedlings. (When I say "we", it was mostly Stu doing the heavy stuff and me getting to do the fun bits – but Iris helped as well).
The plastic collars are supposed to give them some protection from slugs, but really they’ve just got to take their chances – after all it was a weed originally!
