When do I prune my Rose of Sharon?

Woodstock, IL

Hello! I have a question regarding my Rose of Sharon Hibiscus syriacus 'Minerva' (Family: Malvaceae Genus: Hibiscus Species: syriacus Cultivar: Minerva.) I am in zone 5 (Chicago). We planted 2 of them last summer, they are about 3 feet tall, and they did bloom. We are wondering is it time to prune and how much to prune. We have no buds yet. Thanks for any help.

my only experience with pruning rose of sharon is basal pruning after leaf out. is it too tall or irregular form for you? generally i do not do a lot of pruning to these shrubs.

We just don't want it to get taller than 5' or so. Also, do you remove the spent flowers?

We have 3 healthy Rose of Sharons about 12 yrs old. We have found that pruning them at the beginning of fall helps keep them at a reasonable and attractive height and size.. After they are well established, you should probably take off about half of their height each fall., otherwise, they can get very lanky.

A good rule for pruning any flowering shrub or tree is to prune within 3 months of finished bloom time.

no i dont bother dead heading this shrub, but if you want to take the time, it can do nothing but help.
