Train Rosa 'True Devotion' on a trellis, arbor, fence, or pillar for an elegant, flower-filled vertical accent. You will get the best bloom and overall vigor when you plant it where it receives full sun (at least 6 hours of direct light) and where air can move freely through the canes and foliage.
Set the plant into well-drained, fertile soil, keeping the root zone evenly moist during establishment. Add organic matter if your soil is heavy, and mulch to help moderate temperature swings and conserve moisture. Water at the base to keep foliage drier, especially during warm, humid periods.
As a climbing rose, this plant benefits from training: tie new canes in a fan or along horizontal supports to encourage more flowering laterals. Prune in late winter or early spring by removing dead or weak wood, then shorten side shoots and refresh ties as the plant grows. Deadhead spent blooms during the growing season to keep the plant tidy and encourage additional flushes.
At maturity, expect a strong, upright climber in the 72-84 inch range with a spread around 24-36 inches when trained. Provide sturdy support, keep the soil consistently moist but not waterlogged, and feed according to your local rose-care schedule for the most consistent performance.
