The new braches on my tomatoe plants droop and the leaves and blossoma are shriveled. The new branches on one of my Green Ash,(twelve years old) and the same condition is exhibited on an American Hazelnut bush. All of the tomatoe plants are affected but only one Ash out of many and two of many Hazelnut bushes. I have a photo of the leaves but no way to send. Any idea of the cause and treatment?
