Planting and Caring:
Miniatures are wonderful landscape plants. Because the plants are so small when you buy them, it seems as if they’ll take forever to grow and put on a good show. But don’t let that small size fool you. Miniature roses reach full size quickly, and they flower big-time all season long. Miniatures make beautiful up-front plants. Use them to edge a flower border or walkway, or plant them at the base of taller-growing plants.
Miniature roses are actually pretty tough plants. They’re almost always propagated and grown on their own roots, which gives them greater hardiness in cold weather than many other types of roses. Like most plants, however, they’re not real thrilled with harsh winter winds and the nasty freeze-and-thaw cycles that some winters bring. Even though your miniature roses will most likely live and do fine the next season no matter what you do or don’t do, if you live where temperatures regularly fall below 10°F (–12°C), they’ll suffer less damage and thrive more readily if you mulch the base of the plant with leaves for winter protection.
As with full-sized roses, deadheading is pretty much all the pruning you need to do during the growing season. You don’t need to cut back minis in the fall, and in spring you need only prune away the dead parts. If you have lots of minis to prune, a hedge trimmer does a great job. Shear plants back about halfway, meaning that a 12-inch-high plant should be about 6 inches tall after pruning.
