When does a Butterfly Bush start new growth?
Last fall my husband cut back our butterfly bush [our first one, we have only had it for one year.] and left about 24" long stems. We didn't put compost around the base and I don't know where he had found the pruning advice he used.
So far there are no new sprouts/leaves/or life at all.
Should we have cut back to 4" instead of 24"?
Should we have protected the base with compost?
Should we wait until June to see what happens?
Is it going to survive?
