What causes hibiscus flowers not to open?

Question

I have some hibiscus plants, the ones they sell at places such as Lowe’s or Home Depot. The blooms were fine until I planted them (a total of 4 plants) directly in my garden. The blooms grow big, but fail to open.
What mineral if any are they missing?

Answer 1

This is normal transplant shock. You should not do anything to the soil until they recover. This can take up to a few weeks. Keep in mind that these are heavy feeders, and will require fertilization often.
