A couple of people locally have mentioned the idea of an allotment share. I like the idea as our garden is very small and I would love to be able to grow more veg but, while my children are still young, I don't have as much time as I'd like so I think a whole allotment would be too much of a commitment. Has anyone tried an allotment share and, if so, how did it work out? Any pitfalls I should be aware of?
