Well I get the keys for the new house on Friday but don't need to hand the keys in for my current house until the following Monday so I can pull them out and go and replant straight away. I just really want to keep them lolWorth a try - weeds are pretty tough. As long as you have the roots to keep moist for a day or so,they should be ok. I put some dandies with roots in pots last year and they came back in the spring.
One thing I've noticed though is that most weeds seem to do better in well drained soil.
