I was given 3 rose "bushes" back in March and planted them in the front yard. One of them is definitely a Knockout and has bloomed and bushed out beautifully. The second basically shot straight up with two really thick stems covered in thorns and flowered at the top, maybe to reach more early sun? (the house faces north) The third has just sprawled out like a firework, each stem arching over, green, about 4-5 feet long. We thought it may be a sun issue--we'd never seen a climbing variety not climbing on something. Now that I know it's a climbing rose I'd like to set up a trellis behind it/over it, but with the stems sprawled out all different directions, I didn't know the best way to handle it. I've heard any type of pruning in the fall can kill them because they need the nutrients. Any tips? Is this something that will just have to wait until we prune it next year? Thanks in advance.
