Answer: It sounds like they have to be moved, so you might as well try. Dig them up with as much of the root system intact as you can. Replant immediately and water to eliminate any air pockets. If it seems like you have left a lot of the roots behind, you might cut the plant back to compensate for the loss. They may wilt regardless, but should perk up in a few days. Water as needed to keep the soil slightly moist (not sopping wet) while they re-establish. These plants are usually cut back right after they bloom, so I don't think it will hurt them. If you have a choice, the best time to dig them would be right before a rainy day or on a cloudy day. Good luck with the move!
