Black Buds on Hibiscus

Question

I have recently planted Pere Hibi Luna Pink Swirl in my yard. Two plants are near the foundation of my front cement porch, the third in a separate bed away from the house. The two plants have many buds on them, but they have begun turning black and I suspect will not bloom. What could be causing this and how can it be corrected? Is there a soil pH that I should be watching out for? (Previously in this same bed I had black eyed Susans. They grew well but always the leaves had black spots on them. ) I am watering them daily and have fed them each week since planting them three weeks ago.

Answer 1

They are likely bugs. Many of the smaller bugs attach to the plant and move very little. Treat the plant with neem oil and that should take care of them.
