My Hibiscus Has Tiny Grubs Inside The Buds Destroying All The Flowers.

Question

My Dinner Plate Hibiscus has a tiny grub inside all the buds which is destroying all the flowers before they open. I have used standard insecticides with little success.

Answer 1

This sounds like a gall midge larva, or other bud eating insect. Proper gardening practice, such as keeping those infected parts trimmed off will be your first defense. Second will be pesticides.

In order for pesticides to be effective, they will need to be applied regularly. If you find yourself having to do this, then natural pesticides may be the best option. Here are some articles that will help:
