We planted four winter daphne's back in October in well-drained soil and partial shade (we're in the suburbs of Atlanta). They did great throughout the winter, had a small flowering stage this winter, and have gone through a huge growth spurt following flowering. Unfortunately, all four of them have large branches that have begun to significantly droop ("lodge"), and one has significantly drooped over. They seem to be in good health otherwise (no leaf loss; no drooping of the leaves themselves, just branches). Should these branches be staked to encourage more even growth? Otherwise, they look as if they are planted quite unevenly right now. Thanks!
