I have 2 rose of sharon bushes (trees) -- they grow very tall ! I prune them back in the early spring ...meaning April or right before Mother's Day ! Put 1 pail of plant food around the bottom/ roots and they bloom July to September ! Seeds fall off ..you can gather them ..and I have 2 new Rose of Sharons on the other side of my yard now from those seeds! They are quick to root!
