If it is growing leaves, it isn’t dead. It may not be flowering if it is growing in shade….they need full sun. If you are pruning it late in the season, you are pruning off the buds for the next season’s flowers. Only prune in spring. It may also be just slow getting a root system established and won’t flower until it has the extra energy that takes. Feeding it now wilt Espoma Flower-Tone will help it along so it will get established quicker and start making flowers.
