what would cause a trunk of a rose of sharon bush to split in half.
For the second twelvemonth in a row, my rose of Sharon looks like crap. Not all of it, just the side closest to the patio. Which stinks because that'due south the side most visible when nosotros're chilling. I gave it the do good of the doubt and hoped that with simply a little more time it might finally pop. Instead, she pooped. Threats didn't work either, despite the fact that they seemed to with the wisteria. Don't gauge me.
My mom gave me this as a 6-inch cutting nearly eight years ago. I run into it and think of her. So when it took a turn for the worse last year, then once again this year, I started considering possible causes and who I should blame for its demise. Since the dieback has only occurred on one side, I think information technology could be caused by besides much snow cover. We shovel and pile information technology upward along the edges of the patio. Rose of Sharon is sensitive and prone to rot, especially when it's cached under anxiety of snow every winter. Problem solved. I retrieve.
I'd been doing scratch tests on the branches for several weeks. Scratching a alive branch reveals a green underlayer (if information technology's alive) and is a simple mode to decide if a tree or shrub is viable. Everything was light-green until the stop of June when I scratched and got beige. Expressionless. By this point, half of the tree had leafed out while the other one-half that receives less sunday exposure was naked. I held off thinking it might simply exist dragging its feet due to lack of lite compared to the rest of the shrub. Rose of Sharon tin can be slow to leaf out each spring. Information technology'due south one of those plants that tries your patience and just when y'all think she'south a goner, POOF. She's covered in a riot of swelling buds.
That was wishful thinking on my part, so I grabbed the loppers and got to work. Afterward wiping the blades with Clorox bleach wipes to disinfect them, I started hacking abroad. Past the time I finished, the shrub had a peep hole of sorts through the center. Several young shoots were emerging from the base of operations then I'm optimistic about its chances.
How To Grow Rose of Sharon
Hybiscus syriacus, also known as althea or rose of Sharon, is a piece of cake to grow. Whether used as a specimen plant or in a mixed border, it adds tropical flare. When the rest of the garden is beginning to wane, rose of Sharon is only getting started and continues to flower through late summer. Flowers can be either unmarried or double depending on the variety and come up in variations of pink, white, red and fifty-fifty blue. Information technology thrives in USDA plant hardiness zones five-nine.
Full sun and well drained soil are all this deciduous shrub needs. As well much wet or shade and it'll let you know. At approximately 8-ten anxiety alpine and 4-6 feet wide, information technology needs space. Because information technology blooms on new growth, pruning should happen in early jump so you don't risk removing new buds.
It's easy to shape and my but complaint is it's ability to drop fiddling rose of Sharon seeds everywhere. From what I've read, the simply thing that seems to piece of work is deadheading after the flower has shriveled. Merely this too is irksome, particularly when the bush has become quite large. I acknowledge I have yet to do this and resort to hands and knees pulling and swearing under my breath as I yank these guys out every summer. The seed is comical looking. Sort of like a mohawk hairdo.
The U.S. National Arboretum has introduced four varieties that are sterile. They are 'Aphrodite' (pink with cerise eye), 'Helena' (white with red heart), 'Diana' (white) and 'Minerva' (pale lavender). Proven Winners as well came out with 'Sugar Tip', a pale pink variety with variegated leaves. It doesn't produce seed. Because of its prolific sowing ability, rose of Sharon is on the invasive species list of several states and the U.S. Forestry Service lists information technology as a weed.
Rose of Sharon is a Japanese beetle magnet. Fortunately, they're easy to spot and release willingly with a little nudge. I fill a small container with soapy water and encourage them to take a swim. They breathe through their body then a soapy blanket suffocates them and takes care of the trouble without chemicals. This used to be a job for my girls when they were small simply they've outgrown the job. I guess their idea of fun has inverse. Go figure.
A fresh layer of compost effectually the shrub is all I do every spring and this drought tolerant shrub has delivered. I don't even water it. Aside from the seeding issue, rose of Sharon is a pretty low maintenance shrub that comes into its own merely when the garden needs it most.
Do you abound rose of Sharon? Have you tried whatever of the sterile varieties?
