Rose bushes should be spaced at least 3 feet apart, depending on the variety, so air circulates freely around them. Crowded roses bloom less and have more problems with disease than roses that aren't too close together.
In addition to adequate sunlight, roses need proper growing conditions and consistent care. They grow best in light, well-draining soil that is rich in nutrients.
Prune them in spring to remove dead and diseased canes and to encourage compact growth. Remove spent blossoms throughout the growing season to encourage more blooms. Roses need more moisture than many plants. Water them at least once or twice each week so their soil remains slightly moist 1 inch beneath the surface. A wood chip mulch, applied at a rate of 2 to 3 inches thick around the base of the roses, can conserve soil moisture.
Roses also need regular fertilizer applications. Fertilizer applications should stop six weeks before cold weather is expected. Julie Christensen is a food writer, caterer, and mom-chef. She's the creator of MarmaladeMom. Roses prefer a pH of 6. A: Full sun is ideal.
The plants need at least six hours of sun a day. We have some partly shaded areas that get early-morning and late-afternoon sun. Even though they're not getting six continuous hours of sun, they do okay. If you have high, bright shade, like that under a limbed-up tree, roses can do all right, but direct sun is best.
Q: Are there any cultivars that will take more shade than others? A: 'The Fairy,' a Polyantha rose, will take quite a lot of shade.
Another is 'Gruss an Aachen,' a light pink Floribunda. A: We like the Canadian roses in the Parkland and Explorer series.
They have marvelous hardiness for Northern gardeners, and good disease resistance. One of our favorites is 'Morden Blush,' but we have quite a few others. A: Bareroot roses should be planted in spring, by April 15 in Zone 5. Spring planting in the South is in January and February. Container-grown roses can be planted anytime during the growing season.
A: Some mail-order nurseries ship container plants, but most catalog orders are bareroot plants. Newer varieties are likely to be bareroot, too, as nurseries haven't had time to pot them. Many container plants come from local nurseries that buy bareroot plants and pot them up to grow larger. Either bareroot or container plants are okay, but with containers, you have to rely on the reputation of the nursery and whether they know what they are doing. The roses have to be potted correctly to grow.
Q: Are there any other factors to consider when selecting a rose? A: In the last few years, it's become more important to know whether to plant own-root or grafted plants. Some varieties may be available only as one or the other, but where there's a choice, we like own-root. If a grafted plant gets winter-killed to below the bud union, you'll just get the rootstock variety coming back up.
An own-root plant might die in winter, but it will grow back from the roots as the same cultivar. Own-root plants will be smaller than grafted ones at a given age, but they'll catch up. If you get own-root plants, ask for two-year-old ones. A: In colder regions, when the crab apples bloom in spring, prune off any dead material.
Aside from that, just do maintenance pruning to take care of any crossing twigs and inward growth to keep a nice shape to the plant.
Q: What can gardeners do to encourage dormant roses to leaf out in spring? A: We put a small plastic bag over the plant. It should be tan or light brown. Don't use very dark colors. Small grocery bags work well. Be sure to cut breathing holes near the center of the bag, and anchor it down with several stones.
Keep checking under the bag until you see new growth, then remove it. A: We put inches of mulch around our plants. We like wood chips -- cypress is best, but you can use anything except black walnut.
Other possibilities are pine needles, cocoa hulls, sawdust, hay, straw, marsh hay, and old manure. But make sure the manure is well-rotted.
Peat moss and grass cuttings should be used with caution, as they may become compacted and have a smothering effect. Receive our monthly newsletter. Skip to content Temperature Roses can withstand a wide range of temperatures. Light Roses require considerable light to be able to flower.
Soil types The condition of the soil can always be adjusted to suit roses. Containers Roses grow and flower well in most types and sizes of pots or containers, particularly the free-flowering Colourscape varieties.
