Rose 'Climbing Mrs Sam McGredy' Rosa 'Climbing Mrs Sam McGredy' (ClHT)

Water

The Climbing Rose should be watered deeply once a week, ensuring that the water reaches the roots. During hot and dry weather, increase watering to twice per week. Apply approximately 1 to 1.5 gallons of water each time to maintain consistent soil moisture. Avoid overhead watering to reduce the risk of foliage diseases. It's essential to scale back on watering during the winter months when the plant is dormant.

Light

Climbing Roses thrive in a location that receives full sun, with at least 6 to 8 hours of direct sunlight each day. The best spot is an area with unfiltered sunlight that enhances bloom production and helps prevent fungal diseases. Partial shade is acceptable, especially in regions with very hot summers, but may lead to fewer flowers.

Temperature

Climbing Roses perform best in temperatures between 65 and 75 degrees Fahrenheit. They can typically survive winter cold down to 20 degrees Fahrenheit but require protection from frost. Ideal growth and flowering occur when temperatures are within this range, avoiding extremes over 90 degrees Fahrenheit.

Pruning

Climbing Roses should be pruned to remove dead or diseased wood, improve air circulation, and shape the plant for better support on structures. Prune in late winter or early spring before new growth starts. Repeat flowering varieties can be pruned after the first flush of blooms to encourage a second blooming.

Cleaning

As needed

Soil

The Climbing Rose prefers well-draining soil enriched with organic matter, aiming for a pH between 6.0 to 6.5. A mix containing equal parts loam, peat moss, and compost is ideal for providing the nutrients and drainage required.

Repotting

Climbing Roses do not typically require repotting as they are usually planted directly in the ground. If grown in containers, repotting should be done every 2 to 3 years to refresh the soil and address root bounding.

Humidity & Misting

Climbing Roses tolerate a wide range of humidity levels but thrive best in moderate conditions. They do not require unusually high humidity levels; ambient outdoor conditions are typically sufficient.

Suitable locations

• Indoor

  Place in bright, indirect light; prune and support with trellis.

• Outdoor

  Plant in sun, provide support, mulch, prune annually.

• Hardiness zone

  6-9 USDA

Life cycle

The 'Climbing Mrs Sam McGredy' rose, also known as a climbing hybrid tea rose, begins its life as a dormant bare-root plant or as a young potted specimen. Germination occurs when planted in well-drained soil with good sun exposure, leading to the sprouting of young shoots. It enters a vegetative stage, developing leaves and stems, and as it matures, it starts to climb and requires structural support. This rose reaches a reproductive stage annually in late spring to early summer, producing buds that bloom into large, fragrant flowers ranging in color with proper care. After flowering, it may produce hips (seed pods) if not deadheaded. It enters a period of dormancy in winter, during which it conserves energy before beginning the cycle again with new growth in the spring.

Propogation

• Propogation time

  Spring-Early Summer

• Rosa 'Climbing Mrs Sam McGredy', commonly known as Climbing Rose, is best propagated through the method of softwood cuttings. This is a popular technique employed by both amateur and professional gardeners due to its higher success rates compared to other methods. The optimal time to take softwood cuttings is in late spring or early summer when the plant's growth is vigorous and the stems are young but mature enough to snap when bent. To propagate, select a healthy shoot and make a cut just below a leaf node, ensuring the cutting is about 4-6 inches (approximately 10-15 cm) long. Remove the lower leaves and dip the cut end into a rooting hormone before placing it into a moistened mix of peat and perlite or sand. To maintain humidity, cover the cutting with a plastic bag or place it in a propagator. Keep the cutting in a warm, well-lit area but out of direct sunlight until roots have developed, which generally takes a few weeks.
