Bit the bullet yesterday after seeing the local weather forecast, and popped the outside toms in ther places in pots and trays, then loosely covered them with clear plastic, pegged to the wall.
They seem fine this morning, despite a lot more rain and a bit of a chill night...
The runners have been in for a week now, in the open, and also have got going well, so fingers still well and truly crossed for the next day or so before we're supposed to expect warmer weather!
