My grafted rose plants which I got from nursery here in India are getting effected with the die in the grafted portion. I already lost one plant in just two days as the infection was severe I guess. Now the other plant seems to be experiencing the same with the symptoms of leaf burn and die back at the grafted portion. I\'m attaching the photos of the infected plant. Please kindly suggest any remedies if you have experienced the same in your plants. Also my newbie of vinca isn\'t growing well. The same problem of leaf burn even though it\'s just an inch high. It\'s already been a month since I planted the seed. I wasn\'t able to take the picture of vinca as the first two leaves are half dried and curled inwards and the new set of true leaves is tiny enough to get covered with the old. I\'m from India and it\'s summers here but it sometimes start raining quite heavily here.
