Q.rose leaves turning brown and falling off
We have several roses. On all of them, the leaves are turning brown and falling off. We have had a very wet spring with cloud cover.
I am in Colorado and well understand the wet and cold weather as we have been having it too. It sounds like it may have dipped down to freezing or just below freezing temps one night and the cold temps bit them. While this does stress the rosebushes out, they should recover okay. Once things dry up a bit and we get some sunshine again, water them with some water that has a product called Super Thrive in it along with a good root stimulator product. This will help them recover from the stress and shock the weather has caused, it will also help give them the message that it is okay to grow again. You may also notice some of the canes dieing back or wilting and bending over. Prune those canes down to good sturdy cane material. Just as new growth comes on after we deadhead our roses and more buds form, the new growth will come back out. Do not feed them heavily at this time as that can actually cause even more stress.
