“Roses in pots extend the scope and possibilities of gardening. Wide walkways can be highlighted with tubs of roses, entryways can be graced with the beauty and fragrance of roses. Miniature roses can dress up window boxes in the summer, and then be brought indoors in winter to perk up the house.” ~ Dr. Jerry Parsons, Bexar County Horticulture Expert
With the exception of large climbers, most roses can be grown successfully in containers. It is important that the container be large enough to provide ample space for the roots; also to have good drainage, good soil and a location with adequate light and air circulation. The container may be plastic or clay.
Plastic fares better in cold climates where freezing may actually crack clay containers. Clay containers do provide a cooler condition for the roots during hot weather. If choosing plastic, it is better to obtain the lighter terra-cotta color rather than the darker plastics, as they heat up faster. When met with these requirements one can grow miniatures right through roses that can attain a height and spread of up to five feet.
It is important that bush roses and small shrub roses be placed in containers no less than 15 inches in diameter. They will do well there for about two years and then will need transplanting. Roses in containers tend to deplete the soil of its nutrients more rapidly than if they were in the ground. Often they will also outgrow their containers and need a larger home. In this case one can provide the rose with a container one or two sizes up from the previous one. Place your potted roses in a location where it receives some moving air. This will reduce the incidence of fungus-related rose diseases. A rose should also have a full day of sun, or at least seven hours.
Roses that grow from pots must be watered daily during the hot, summer months. It’s relatively easy to move them to a sheltered position in extreme weather.
