How to Grow Rose

Shrub

Roses are among the most beloved flowering shrubs in American gardens, prized for their fragrant, colorful blooms and long flowering season. They range from low, spreading landscape types to tall climbers and formal hybrid teas, so there is a rose to fit nearly every garden style and space. US gardeners grow them for cut flowers, hedges, and dependable season-long color.

Planting

Plant roses in early spring once the ground has thawed and is workable, or in fall at least six weeks before the first hard frost in your area. Bare-root plants go in while they are still dormant, while container-grown roses can be set out anytime during the growing season. Choose a site with at least six hours of direct sun and well-drained soil that is rich in organic matter, and space plants about two to three feet apart so air can move freely between them. Set the plant so the swollen graft union sits at or slightly above the soil line in warm regions, and a couple of inches below the surface in cold-winter zones.

Care

Water deeply once or twice a week at the base of the plant rather than lightly every day, keeping the soil evenly moist but never soggy. Feed in spring as new growth begins and again after the first flush of bloom, following the directions on whatever product you choose. Deadhead spent flowers regularly to encourage repeat blooming, and prune out dead, weak, or crossing canes in late winter or early spring before growth resumes. Tie the canes of climbers and tall types to a sturdy support, and spread a layer of mulch to conserve moisture and steady the soil temperature.

Bloom time

Most modern roses bloom from late spring through the first fall frost, sending out repeat flushes every six to eight weeks. Once-blooming old garden roses instead flower heavily for a few weeks in early summer.

Garden uses

Roses make excellent cut flowers and shine in mixed borders, formal beds, hedges, and large containers. Single-flowered and shrub types also draw bees and other pollinators to the garden.

Tips

Water in the morning and at the base so the leaves stay dry, which lowers the risk of leaf disease. Pick disease-resistant varieties suited to your region to reduce upkeep, and always prune with clean, sharp tools. Good air circulation and a yearly renewal pruning keep plants vigorous and blooming well for years.
