Ours have grown so well this year and have spread all over the place so we
are hoping for a decent crop unlike the one previous time we tried them
(provided the slugs haven't feasted).
So when do we harvest?
Do we wait for the first frost to kill off the foliage or just dig them up
ASAP?
How do we store them over winter?
and provided it's worth repeating the exercise.....
Is it possible to save some plants for next years planting?
