I have a row of acuba about 5 ft tall and 3-4 ft wide stretching along **my side** of **my** hurricane fence between me and the neighbor. The same stretch of acuba continues around fence corner and along the back fence and i have another patch of 6 - 6 ft tall acuba bushes next to a patio providing some privacy from the side neighbor.
Several months ago about 3 of the very heavily grown Acuba patches at the front or beginning of the run along the side fence started wilting on the top, then they kind of recovered over several months , then they started wilting again about a month ago and they have steadily gone black but not all over. Just some of the stalks have died and the ones that have not died seem to be just the ones that are more on my yard's side.
I first thought disease, pests or drought but none of the other Acuba bushes in my yard have wilted.
Is there a way to check if the bushes have been treated with weed kill etc .. or maybe there is some other method of making them sick to check for ?
helpful replies appreciated. robb
