Moving plants when moving house (perennials)?

I suggest you take some, leave some.... perennials are easy enuff to divide and that gets you smaller pots to move and both you and the new folks get the joy of them.... and in a few years, you, at the new place, will have just as many as you had..... and you don't have to ask anyone's permission to take the divisions!!....for the rose, it's all or nothing.... it's the wrong time of year for rose cuttings to start well....

if you're doing it in the spring or fall, it should be easy. In fall, cut the plants back as you normally would. Dig out as much of the root ball as possible and put in pots. Keep them watered and sheltered until you move.

It may take them a little while to reestablish once you replant them, but they should be fine.

for the bulbs, like allium, just lift and store them in a bag of peat moss, then replant when you get there.

We have moved hostas and herbs. from one location to another. Give them plenty of water. They look tough for a few days but come around.

If they are planted in the ground, you need permission to remove them, either from the landlord or, if you own the house, it needs to be revealed in the sale paperwork. If I was moving them, I would place in pots for the journey.
