Moving poets

hey – we have a member, not on DaffNet, who needs to divide some of her poets. I know they hate being out of the ground, so need to be replanted immediately. But what about dividing clumps? I would guess you’d separate out the bulbs in a bucket of water to separate the roots w/o damage, but should she separate down to single bulbs, or just say divide a clump into two smaller groups? She needs to do move/separate these guys while the foliage is still up and the rain is still falling… -s
