When you go shopping for your rose plants, you’ll need to understand the conditions needed for roses thrive. Determining the best place for your rose bushes is key if you want your roses to do well. Roses need sunlight – at least six hours a day to thrive. And, in most locations they prefer to have much of that sunlight in the afternoon when the sun is its hottest. So, find a spot in your garden that gets morning and early afternoon sunlight and you’ve just discovered the best place for your roses . If you are using a container for your rose it should be large enough to support the size of the plant so if your rose says it will get 3-5 feet you need to get a container that is at least 18" inside diameter or more.
