White Fungus on Hibiscus Buds
There is a white fngus that is preventing our hibiscus blooms from forming properly. You can see in the picture the new bud is all shriveled up and not growing properly. This fungus only shows up on the flower buds and leaves on the same stem. Every single bud looks like this and our mild flowering plant spray (BAYER ADVANCED Rose and Flower Insect Killer) is not doing the trick! Please help.
