Hybrid and non hybrid hibiscus

I have many hibiscus plants in my yard. All of them seem to not be blossoming and/or very sparsely. They all have numerous buds which seem to turn yellow in many cases and fall off. It seems strange that the whole yard of at least 50 plants are doing the same. The leaves also, esp. in the hybrids, are shriveling up in a shriveled cluster with the bud. It appears something is sucking the life out of it. The plants are nice and green. What is it and what can I use to correct it?

There can be several reasons for yellowing leaves on Hibiscus, including infestations of insects.

Neem Oil is a good treatment, it is safe for people and pets and should take care of any insects on the plants.
