Hi - I'm a 3rd generation NYC apartment dweller, so please forgive my ignorance. I just bought a house in the burbs and have a backyard that has several trees, flowers and shrubs planted in it. I don't know anything about gardening, so I've just started reading up and I really want to learn as much as I can. Anyhow, there's a rosebush that I'm guessing has been around for quite awhile, with a peach tree right behind it, and some other shrub/tree next to it. The rosebush looks really wild to me and I don't know where to start trimming. Some of the vines on it extend up into the peach tree, and they must be at least 15 feet long! If anyone can give me any tips on how much of this bush I should trim, and if this type of rose should be given a trellis/support, etc...any info would be appreciated! I took a pretty bad picture of it, but it should give you an idea. Thanks!! :-)
Roses are often grafted.
This means that a type of rose that grows nice flowers is grown on top of a rose that has a strong root system.
The root system can also grow branches, and often they will look like a climbing rose.
I am not saying this is what has happened to your rose, but it is a possibility.
Go ahead and cut away the parts that are too tall.
If it is growing with a lot of arching branches, then it highly likely is a climbing rose, and will need some support.
If the branches are growing from under the ground, then it might be the rootstock growing.
These can have nice flowers, often they are red, and do not have as many petals as more formal roses.
When you see flowers, take a picture and post it here.
