All you need to know about pruning Rose Of Sharon

  1. To pruning the Rose of Sharon, you must wait until winter or early spring. In general, the plant does not require too much care. However, if you decide that you need to prune the bush, do so during the colder months while the plants are still in their dormant state. This way, you will help grow new growth as the weather warms up.
  2. That is a general rule that the best time to prune Rose of Sharon is between March and early May (for US residents) before the flowers begin to open. Cutting the branches too early or too late can cause it to enter a shocking state, making it susceptible to different elements and delaying new healthy growth.
  3. Discard dead or damaged wood. Give special care to branches that appear damaged, rotten, or colorless. Leave only the strongest and healthiest parts of the branch. You can try to cut each shoot as close as possible to the most extended branch connecting it as far as possible. Previously, if you were pruning yourself, you would need to be proficient with gardening shears to handle most pruning.
  4. You may find branches that are thicker or tougher than others. In such cases, you may need extra-long, robust scissors or a regular hand saw for pruning.
  5. If you are unsure whether a branch is damaged or dead, try rubbing a little on the bark. If the wood underneath has a greenish hue, then the branch is still considered healthy.
  6. Remove the branches that cross each other. Check the inside of the bush to see if any shots are overlapping or getting tangle between them.
  7. Trim the two most bent branches from the base (just one of them is fine). When doing so, you can also check for any tangled or bent stems near the ground.
  8. Remove the cross branches to be able to clean the middle. By doing so, you have provided a place for air circulation, which is essential to keep pests and diseases away. Apart from that, you will also make the bushes look good.

Pruning further

  1. Remove the teat that is visible from the base of the plant. For those of you who may not know, a pacifier is a thin stem that grows vertically at the root of a woody shrub. Generally, you can find a lot of Rose of Sharon. Pacifiers usually appear mostly on the underside of main branches or directly on the ground beneath the plant. The best way to treat pacifiers is to cut them as close to the base as possible, as this will remove the connection they have with the plant roots and make their growth slow. Pacifiers can germinate and come back, which means you’ll need to cut them again about 2 or 3 times a year.
  2. Pacifiers not only make your rose bush look ugly, but they also weaken the essential nutrients in the soil if you don’t remove them right away.
  3. If it seems that the Rose of Sharon is not growing well or has grown heavily, you can trim the bush to two-thirds the size. It would be better to get more growth than you cut. You don’t need to worry; as long as the hardwood at the plant’s base is intact, Rose of Sharon will return to producing flowers from year to year.
