We trimmed my Rose of Sharon in early spring and now I have leaves growing from the trunk. Will these become branches?What should I do?
Dear gardener, thank you for contacting the Toronto Master Gardeners.
You did the right thing pruning your Rose of Sharon (Hibiscus syriacus) in early spring in order to control size and shape, as the flowers of this shrub are produced in new wood (from this year).
Pruning the shrub back to 2 to 3 buds per branch in spring encourages larger flowers. It is also a good idea to remove branches growing inwards or crossing. Always, remove dead or injured branches.
In regards to your question, Rose of Sharon is by nature a multi-stemmed plant. Some of the leaves you see growing from the trunk will become, with time, new branches. I would suggest that you wait and see which ones do and which ones you would like to remove in order to keep the shape you desire.
Good luck and enjoy your beautiful shrub.
