My hibiscus plant is losing 1 branch every day. The branches go from looking healthy to be dead overnight. The leaves don't turn yellow. I have 2 plants side by side and the problem is only with 1. I had this problem last summer and I lost the plant.
I had put down several treatments and nothing works. When inspecting the branch, I can see tiny holes as if something went in.
Any advice is appreciated.
Thanks.

You have a problem in the soil and it is called root knot needies and they are eating the roots of your plant. You will need to get the tree out of there and see if you can save it by taking the knots off the roots of the plants. I have had these here on the islands and it is almost impossible to save the plant. The bugs live in the dirt and attach themselves to the roots of the plants and just suck the life out of your plants. Basially there is not a lot you can do for this but remove the plant and see if you can save it.
This is called " Cankers". This is dying plant tissue. As it gets worse, the limb becomes dry and brittle.
This problem sure sounds like root rot (several causes and not all relate to too much water).
You may be able to save the plant if you dig it up and really trim it back and remove anything that remotely looks like diseased.
You'll probably have to treat the ground and not plant anything in that area for several months.
I would recommend you ask your county extension agent about this as they can give you the information you need to keep this from happening again. They are a valuable resource for solving plant problems.
