How to Prune a Hibiscus Syriacus 'Aphrodite'

Prune Hibiscus syriacus "Aphrodite" before new growth starts in early spring. Although it is densely branched, Aphrodite grows relatively slowly. Except for removing diseased or damaged branches, pruning is necessary only every other year. Create a plan for pruning, so that only the necessary cuts are made. To create the plan, consider the plant's natural form and choose branches that are damaged or diseased for removal, as well as those that do not fit its natural shape. Correct pruning maintains the natural shape of the plant. Hibiscus syriacus "Aphrodite" has a shape like a vase that is narrow at the bottom but widens at the top.

Remove all dead, broken, diseased or insect-infected stems or branches by cutting them back to where they begin on the plant, either back to a strong lateral branch -- the branch they're growing from -- or to the plant's main shoot. Use clean, sharp, hand-pruning shears. Most hand-pruning shears cut stems up to 1/2 inch in diameter. Use lopping shears for larger diameter branches. Clean tools immediately after making a cut on diseased wood by immersing the blades in rubbing alcohol or household bleach.

Prune stems or branches that suck energy from the plant or block light from it's interior and look messy, such as those nearly touching, crossovers and suckers. Also, cut branches that are too long or too low -- any that do not conform to the shrub's natural growth. This helps Hibiscus Syriacus "Aphrodite" maintain its natural shape. Over time, its branches, which grow up and outward, begin to arch over.

Cut branches at the top of the tree to shorten the bush, if desired, through the pruning process known as "heading." Prune back to a lateral branch, or bud -- a knobby area from which new branches and stems grow -- making the cut approximately 1/4 inch above the lateral branch or bud. Longer stubs heal more slowly and allow diseases to enter. When cutting back to a bud, make the 1/4-inch cut at a slight angle above the bud, to help moisture flow off. If you want the bush to grow more shoots that spread outward, cut above an outward facing bud; otherwise, cut below, which limits the plant's growth.

Stand back and review your pruning. Remove any stems and branches you've missed.
