Pam- I'd never keep any actually in the ground up here. All mine in pots & they are wrapped, covered & stored in a cold, very, greenhouse or insulated coldframe over the winter. Friend does have a good sized clump in her south facing front garden. Dont think she ever protects them, but she is nearer to the coast, by about 11miles.........
Have finished off some vino & got the washing back inside. At least GW on tonight, but always 'tape' so if sport good wont worry.
Always fancied learning to fly.... ever seen formula 1 air-racing? Totally hooked when seen on IOM couple of times. J.
