How to Trim Rose of Sharon Bushes


Rose of Sharon (Hibiscus syriacus) bushes have white, pink or purple blooms in summer and fall. The plants are vase shaped with long straight stems, unless they have been severely pruned. Most Rose of Sharon bushes need little or no trimming, unless it is required to control the size of the plants, which can grow 8 to 10 feet tall and 4 to 10 feet wide.

Step 1

Trim Rose of Sharon bushes in the winter before new growth appears. Use hand pruners to cut limbs up to ½ inch in diameter and lopping shears to cut larger limbs. Cut limbs at a 30-degree angle at a bud, or back to a side shoot or the main branch.

Step 2

Use hand pruners or lopping shears to remove diseased, damaged or dead limbs.

Step 3

Remove crossed and bent limbs with hand pruners or lopping shears.

Step 4

Use lopping shears to remove older branches that have lost vigor and do not flower heavily.

Step 5

Use pruning shears to shape the bush by removing long or wayward stems.
