my rose of Sharon was planted and looked amazing for 4 weeks. Big flowers and lots of them, dark lush green leaves. Recently, the leaves have started to turn yellow and dry up and there are only a few flowers left. What should I do?
Check to make sure that it wasn’t buried too deep. Get down and brush any mulch or soil away from the trunk until you find the original soil level where the trunk entered the soil in the pot or ball that the shrub came in. Bark or soil piled against the bark of trees and shrubs slowly strangles the plant. Keep it watered through fall until it goes dormant after a couple of frosts. Althea also leaf out VERY late in spring so be patient then…the first leaves won’t show up until the lilacs in your area are starting to bloom.
