they can be ready now, so why not excavate one and see. leave to dry and store in a cool place.

Dear Seaburngirl: I have now excavated them all. Nine out of ten so not bad. I put them in a larger container this time. However, they are still a little small but then I have never managed to get them bigger. They are now drying out in the greenhouse but it is hot at the moment. If only I had one of those basements you are often told to keep them in but some of us have very small flats! Thanks a lot for replying and may you have a productive season!
