You're supposed to replace strawbs every 3 years I think it is, Dom... I put my babies in little pots, still attached to mum and when they take off, set em freeeeeeeeeee!!
The old boy next door has a moving strawberry bed..

he gets rid of the oldest with the new ones, and just brings the bed forward and back again each season, apparently it's been all over his gardn over the years...
Or bung on the compost heap if you don't want them, or give them away, or a nice hat deco or something?
