Growing Roses in Containers
- Choose the right kind of rose. Compact, disease-resistant types are best suited to pots. Avoid climbing roses or large shrub roses (oops!). Make sure the plant fits your hardiness zone.
- Choose the right kind of pot. There are really only two main points to picking a pot for your roses. Bigger pots are always going to be better. Choose a pot that fits your rose type the best, see this article for guidelines. Because roses have deep roots, deeper pots are always better than shallow ones. Also, the bigger the pot, the less you'll need to water the roses. Make sure it has drainage holes, it is vital for the rose's health. Half barrels are a great size choice and the wood exterior looks really nice against the rose's foliage. I chose large plastic pots because of my budget, and because I wanted the pot to be its home for several years. If this is the case for you, you may want to do what I did and pick something that won't rot.
- Plant roses where they will receive at least 6 hours of full sun per day. Use quality potting mix enriched with compost to increase the soil's water holding capabilities.
- Water regularly so that soil doesn't dry out, but don't keep it wet. If it's too swampy it could rot the roots. To help conserve water from evaporating, add a 2 to 4-inch layer of chopped and shredded leaves, grass clippings, or shredded bark around the base of your roses. Allow about an inch of space between the mulch and the base stem of the plant. This will help prevent rotting.
- Fertilize with rose fertilizer often for more blooms. A general rule of thumb is in the Spring, once new growth shows up, and then after each flush of blooms – about every month to 6 weeks. In colder zones, stop fertilizing a couple months before the first frost of the Fall.
- Deadhead spent blooms to keep the plant in bloom. To do this, just trim each spent bloom back to the first leaflet that has 5 leaves. Stop deadheading all your rose plants 3 to 4 weeks before the first hard frost to stop encouraging new growth. Do not prune the roses during the fall season. You can, however, cut off any dead or diseased canes.
- Re-pot your roses every two or three years to give them fresh soil. You can even prune the roots if you want to keep the plant small. Transplant into a larger container if you notice the output of blooms decreasing.
