The misting may have helped, but the Wilt-pruf was of little help. You can 't prevent transpiration in plants with no leaves, as there is very little, if any transpiration going on. You may actually inhibit leafing out, since you're applying a sealant to the buds...

I think the late leafing had more to do with an overwintering problem. The plant's roots may have died back a bit, or some other problem that forced the plant to set new buds. If they are new sets of buds, the plant has drawn deeply on its resources to make them. It bears close monitoring this spring and summer to make sure it regains strength.

Paul,

It may just be sulking. Put it in full morning sun. Keep it moist (but not wet) Wait until mid-June before acting rashly...
