Transplanting LAVENDER 'out of season' zone 6/7
Have transplanted many perennials when in bloom, successfully, though not at suggested times. These are my first lavender plants and due to construction in three weeks, I MUST move five bushel sized plants that are in bloom now. Would you pros suggest immediate pruning, so the cut tips have a few weeks to harden before moving, or should I prune just prior to digging and transplanting to the temporary site (for three months)? How much top growth should I remove? In Sept, the plants will be returned about five feet from their present site, so soil will be familiar.
I always use surveying tape to mark north orientation and reset plants the same. When I transplant perennials in summer, I also provide semi-shade for sunny plants for the first week. Could I divide these plants at this time without substantial losses? The plants were grown from small 4" pots planted spring 2007 and have never been divided.
