Miniature Roses
-
As true roses, miniature roses come in many types and colors. They are easy to grow and more winter hardy, making them an ideal container rose. With bush heights of around 1 foot, some are compact and bushy like Rainbow's End. Others grow to almost 3 feet like Irresistible. Hanging basket miniature roses, such as Sweet Chariot, Orange Honey and Green Ice, have canes draping over the edge of the pot. Climbing miniatures include Red Cascade, Climbing Earthquake and Jeanne Lajoie.
Polyanthas
-
With tiny blooms covering the plant, Polyantha roses are low-growing and bushy. Its size at 3 to 4 feet high and 2 to 4 feet wide and abundance of blooms make it ideal for containers. Recommended Polyantha cultivars include, Katharina Zaimet, Marie Pavie, Mrs. Nathalie Nypels and Cecile Brunner. The Fairy is ideal for Northern gardens with cooler temperatures.

Containers
-
Other than large climbing roses, just about any rose can grow in a container. The size and type of container become the critical elements. Roses require a lot of rooting space and water. Choose a container large enough for the rose variety. Five gallons is usually adequate for miniature roses and small polyantha roses. Hybrid tea roses, large floribunda and gradiflora roses need 15 gallons. Wooden pots like whiskey barrels are sufficient but dry out sooner than clay or plastic pots. Clay planters keep roots cooler in hot weather, but are heavier than plastic containers. Plastic containers are good if a lighter color is chosen minimizing overheating the roots.

Tips
-
Use quality potting soil for container roses, as they use available nutrients quickly. Adding bone or blood meal helps replenish needed nutrients. Placing gravel or medium-sized rocks in the bottom of the container maintains good drainage. Fertilizing and watering regularly promotes blooms throughout the growing season. If growing multiple containers, space them about 2 feet apart. This prevents the spread of disease and allows for good air flow. Winter container roses in temperatures above 25 degrees F and below 50 degrees F. This allows them to go dormant without succumbing to freezing temperatures. Prune when plant is dormant.
