Poor Flowering on Rose of Sharon After Pruning
I planted an althea bush (Hibiscus syriacus) a year ago. It flowered great that year. In fall I pruned it back. It grew 2 feet but only bloomed on the tips of the branches.
Prune althea bushes, also known as Rose of Sharon, in late spring. Prune young plants hard to encourage branching at the base of the plant. Once established little pruning will be needed. Prune to remove deadwood and maintain the size and desired shape. It is not unusual for young plants to produce limited flowers. Much of their energy is going to produce roots and new growth. This combined with hot dry weather can limit flowering. Prune as needed next spring before growth begins. Avoid high nitrogen fertilizers that can also interfere with flowering. Then sit back and wait for the beautiful blooms.
