Climbing Tea Rose

Water deeply 1-2 times per week, providing 1-2 inches of water each session to saturate the root zone, and avoid wetting foliage to reduce fungal disease risk. Reduce watering frequency in late fall and winter to prevent root rot, and ensure the top 1-2 inches of soil dries out slightly between waterings to avoid over-saturation.

Plant in a location that receives at least 6 hours of direct, unfiltered sunlight per day, with morning sun preferred to dry dew from foliage quickly and minimize disease risk. They can tolerate light afternoon shade in extremely hot climates, but reduced sunlight will lead to fewer blooms and weaker, leggy growth.

Grow in well-draining, loamy soil with a slightly acidic pH between 6.0 and 6.5, amended with compost or well-rotted manure to improve nutrient content and drainage. Avoid heavy, clay soils that hold standing water, as this will quickly cause root rot and decline in climbing tea rose plants.

Feed with a balanced, slow-release rose fertilizer in early spring just as new growth emerges, followed by a second application after the first bloom flush to support repeat flowering. Stop fertilizing 6-8 weeks before the first expected fall frost to prevent tender new growth from being damaged by cold temperatures, and avoid over-fertilizing with high-nitrogen formulas that promote leaf growth over blooms.

Thrive in temperatures between 60-85°F (15-29°C), and can tolerate winter lows down to -10°F (-23°C) if provided with proper winter protection such as mulching around the base and wrapping canes in burlap in colder zones. They are heat-tolerant in most temperate regions, but extended temperatures above 90°F (32°C) may cause bloom drop and scorched foliage if not provided with occasional extra watering.

Prune in late winter or early spring before new growth begins, removing dead, damaged, or crossing canes first to improve air circulation through the plant. Train long, healthy canes to their support structure horizontally to encourage more lateral bloom-producing shoots, and deadhead spent blooms regularly throughout the growing season to promote repeated flowering flushes.

Most commonly propagated via hardwood cuttings taken in late fall or winter, selecting 8-12 inch long, healthy dormant canes, dipping the cut end in rooting hormone, and planting in well-draining potting mix until roots develop in 2-3 months. Grafting onto hardy rose rootstock is also common for commercial production to improve disease resistance and cold hardiness, while seed propagation is not recommended as it will not produce plants true to the parent cultivar.

Prefer moderate humidity levels between 40-60%, and good air circulation is critical to prevent fungal diseases such as powdery mildew and black spot in high-humidity environments. They can tolerate average household humidity if grown indoors, but avoid placing them near drafty heating or cooling vents that can dry out foliage excessively.

If grown in containers, repot every 2-3 years in late winter before new growth emerges, using a slightly larger pot with drainage holes and fresh, rose-specific potting mix amended with compost. Trim back any circling or damaged roots during repotting to encourage healthy new root growth, and water thoroughly after repotting to settle the soil around the root system.
