I have a bit of room left on the allotment and some
potatoes that are sprouting.
What is the latest to plant them and get some success?
Would I be wasting my time planting them now ?

I have also found some onions that are started to send
out shoots, same question applies for those.

You need 14 weeks growing for main crop potatoes and that takes us to about
the 19th September. Probably won't get a frost by then so should be fine.
If you mean fully grown onions that are sprouting then if you plant them you
will get flowers and eventually seeds. If it's sets that are sprouting I
wouldn't think there was enough time left for them to grow into proper
onions but worth a go anyway.
