How should I prune my Wiegela?

Question

My Wiegela is mostly made up on branches that sort of gracefully drape toward the ground. However, this summer new branches have grown straight up and are thicker and with bigger leaves than the rest of the plant. Is this normal, should I cut them back or leave them alone? Will these branches bloom as profusely as the rest of the plant did this Spring? I have no photos to send.

Answer 1

If you fertilized with a high Nitrogen fertilizer, or manure it could be contributing to the vigorous vegetative growth at the expense of flower development. You can shape the vertical growth down and refrain from any more fertilizing until fall.
