Some varieties of easy-care Flower Carpet roses can do extremely well in containers, providing the container is large enough.
The container should be at least 20 – 24 inches in diameter and equally deep (the larger the better). It’s important to use a good quality potting mix. The containers can be placed in the sun or semi-shaded area. Because the roots don’t go as deeply in containers as they do naturally in the ground, the key is to make certain that the containers aren’t allowed to dry out. Then just feed them a few times a summer. The Flower Carpet varieties or colors that seem to do best in containers include White, Red, Pink, Coral, Yellow and Appleblossom. (The newer varieties of Amber, Scarlet and Pink Supreme tend to get larger than the others do unless you had a very large container, you’d be better off going with the other colors mentioned).
