Should I replace a barely-alive Rose of Sharon?
So last year I planted 4 Rose of Sharon, and started training them to tree form. They started about 2 feet and grew to 5-6 feet.
After a harsh winter, 3 are showing buds from top to bottom. But the 4th--and in basically the same conditions--is only showing a single, small bud a half inch above the soil. I'm now worried that the rest is dead, and I may have to cut it all the way down.
Is it worth waiting to see if it will all grow back up and be able to train it to tree form? Or should I just buy a replacement?
