hollyhock blooms

Question

I planted a hollyhock last spring, purchased from a local nursery. It is planted in a large wine barrel. The plant is healthy and looks happy, but again this year there are no blooms. Do these plants have to grow a couple of seasons before they bloom? It is planted in full sun and watered daily as we have high temps in the summer.

Answer 1

The soil may be lacking phosphorus, which is necessary for blooming. Use a phosphorus-rich fertilizer or add bone meal to the soil around your plants and see of this helps.
