The leaves on one of our rose bushes have turned brown from the middle of each leaf and are limp and starting to curl. The edges of the leaves are greenish brown. This has affected most of the leaves on the bush and the buds are not growing or opening. Please help, as I can find no information on any website.
Water the rosebush well. Then give it a treatment of either Bayer Tree & Shrub Granules or the ones made specifically for rosebushes. It could also be that a neighbor hood dog has peed on the rosebush as that will cause the same effects you have described. In that case, prune off the effected leaves and water the rose well. Water the rosebush with some water that has both a good root stimulator in it and a product called Super Thrive in it. Do this the next 4 to 5 times the bush needs watering and relief should be seen.
