Roses are extremely popular plants for backyard gardeners. Growing roses in containers is becoming more common because of some of the new varieties of roses, improvements in fertilizers and the increase of larger and lighter containers. Every rose will not grow everywhere, but with a little effort and planning, you can add roses in places where only your dreams bloomed before.
There are several benefits of rose gardening in containers. Containers give gardeners more options for creating a display within the garden. They can move roses that are in bloom to a prominent position and put plants that are not looking their best where they will not detract from the display. Gardeners are able to move the containers to chase the sun. Containers give anyone without garden space the option to grow roses. Renters can take their roses with them when they move, without having to uproot their roses.
Rose Magazine says that you can grow most roses in containers, with the exception of the most vigorous climbers. Miniature roses grow well in containers and their scale means that, in many instances, they will look good in smaller containers. Colorado State Extension program suggests growing "floribundas, hybrid teas and grandifloras, and even some of the modern shrub roses" in containers. In addition, Marina, Europena, Electron and Intrigue make good selections, according to the AgriLife Extension of Texas A&M University.
Any container shape will work with your roses, but The AgriLife Extension of the Texas A&M System recommends that you use pots that are a minimum of 18 inches across and 14 inches deep in order to foster proper root development. Choose the material the container is made from based on your climate because that will affect how much water your plants retain, as well as the high and low temperatures the plant will experience. Avoid containers that will cause your roots to overheat, specifically containers that because of color, composition and location absorb and hold sunlight and heat. The container must provide good drainage, but do not choose a container where the soil will dry out too fast. Soil composition as well as holes in the container account for drainage. The Colorado State Extension program advises against using a saucer underneath the pot, because of the increased likelihood of root rot.
You will not have much more difficulty providing roses with the right kind of soil in containers than you do for your roses in the ground. Keep in mind that roses are heavy feeders and that roses in containers will deplete their nutrients very quickly, according to Rose Magazine. Expect to change the soil every three years. This is an opportunity to replenish the nutrients and to evaluate the roots to determine if they are root-bound.
Place the containers where you will be able to monitor their moisture levels and inspect them for aphids, leaf damage and other problems. Either move smaller pots indoors for the winter or protect them with deep layers of mulch. Wrap larger containers in burlap to give the roots added warmth. Soil in containers warms faster than the ground soil, be prepared to inspect roses coming out of dormancy earlier than you normally would for your in-ground plants.
