Currently I'm going over with empty pots of soil, finding runners, and
clipping them into the pot (so still attached to original plant).
I think I need about 200, including a bunch to give to my dad, so it's a
long work in progress. I'll leave them in pots until the spring, then
transplant them.
Thanks Vicky, Do the runners have to be attached or can they be separated
and replanted ??

I'm going to leave them attached for as long as possible, but come spring
I'm moving them 50' that way ---- so they will definitely be chopped free.
You can probably chop them free as soon as they look big enough to thrive on
their own, but that's for you to decide.
