My husband and father-in-law planted an almond tree 2 years ago. It is about 9 feet tall and was growing really well and was healthy. Lately it has been covered in beetles and the leaves have been getting chewed on. I am not a gardener by any means but I told my husband I used Dawn dish soap water mix on a rise plant I had, and it kept the bugs away and grew really nicely, so he tried it.
The very next day, all the leaves were wilted and turning brown. Did my not so expert advice kill the tree, and is there anything that will help revive it? I Googled the mixture and it says that hot and sunny weather can overheat the soap and burn the tree. This has been the case in Wisconsin since he sprayed it.
My father-in-law was pretty partial to this beloved tree! Can you please help me decide what to do next?
