Pruning Rose of Sharon plants, also known as hibiscus syriacus, should be done annually to keep the plant healthier, to encourage new plant growth and to keep it under control. Allow a Rose of Sharon plant to fill in through the growing season, trimming it back one third while it is dormant, with advice from a sustainable gardener in this free video on gardening.
Hi, this is Yolanda Vanveen, and in this segment we're going to talk about pruning your Rose of Sharon plant, also known as Hibiscus Syriacus. Now, the Rose of Sharon is a beautiful shrub, kind of like a small tree, and it has gorgeous flowers on it that look like a hibiscus, and it's very hardy in cold climates. It'll come back no matter what; whereas, you're going to lose your hibiscus. But if you buy a property or you, you will find it's a plant that has been around for a long time. So, when we moved into our property we had some Rose of Sharon that were just huge, and lanky, and out of control. And so, you can save those plants by pruning them, and the rule of thumb is prune back only one third of the plant per year. So, if you've got a plant that's really out of control take your time, and prune one third the first year, one third the second year, and one third the third year. And by just cutting it back one third, and cutting back at least every three branches out of it, leaving just main branches remaining, then you will find that it'll fill in and be really beautiful the next year. And you want to just trim em' down not more than just one third of the size, and when you trim don't good it just into dead wood. You want to make sure there's some new growth. There's gotta' be buds or some foliage. So, cut back just where the foliage line is; never farther than that because then you'll just have dead wood. But, Rose of Sharon are very forgiving, and even if you cut em' to the ground the suckers will still come up, so you always want to cut a lot of the suckers out, or pull em' up and put em' into a new spot, and you will find that you can enjoy your Rose of Sharon for many more years.
