Hibiscus Insect

Question

My hibiscus looks healthy, but there are no flowers coming anymore because when the bud is very near to open, it falls like it was cut with a perfect saw cut. I have seen some leaves with round holes (as eaten), and I noticed an insect with round, roughly shape brown color. What I can do to restore the capability to have flowers and kill the insects?

Answer 1

Try neem oil. It's good for many types of insect pests. Here is more information: https://www.gardeningknowhow.com/plant-problems/pests/pesticides/neem-oil-uses.htm
