thank you so MUCH for answering my post!
I trimmed it back half way...and watered it well this week
and I think it will be okay ..
I would never prune back
later than mid August due to I did that one year on oct lst
and we did not have a frost or freeze till late november and it
killed my butterfly bush...
it did not have time I guess to harden
off in the stems
where I pruned it back to half the height and moved it 4 foot over
to another spot in the same flower bed...
I would have thought in zone lower 8 it would have gotten established
from moving it and pruning it on oct lst but it killed it...
I normally prune back March lst all my butterfly bushs, salvias or anything else in the flower garden
in our area..and that is the best time for us..so the plant does not go into shock...
Thanks again
Sheri
