I have a friend who has many hollyhocks in her yard. She has offered me when some of the plants stop flowering (go to seed) that I may dig some of them up and take the roots. If I do this, when should I plant them and how would I best care or prepare the roots?

The best time to transplant is in the spring, but if your neighbor needs to clear them out, you can do it now. Take as much soil as you can, transplant quickly and water well.
