I want to take my dahlias with me to my new house - help?

I don't know I'm afraid but hopefully others will be along soon.

Can I ask what the purpose of the poll is?  I don't understand the two options or what you are asking us to vote on.

Poll axed

It's not an ideal time to move anything but I think you're right to cut some of the top growth off when you try to move them. All the leaves now will mean the plants will dry out a lot. So keep the pots well watered and plant them out in some good compost as quickly as you can. Then keep them watered until they establish.

Great minds...
