Blair Rose Rosa 'Blairii Number Two' (ClBb)

Water

The climbing rose known as 'Blairii Number Two' should be watered deeply and thoroughly to encourage root growth, which typically means using about 1 gallon of water per plant during each watering session. During the growing season, watering should usually occur once or twice a week, allowing the soil to dry out slightly between waterings. However, the frequency should be adjusted depending on weather conditions; more often during hot, dry spells and less during cooler, rainy periods. It is important to avoid overhead watering to prevent leaf diseases and instead direct water to the base of the plant.

Light

'Blairii Number Two', as a climbing rose, thrives in a location that receives full sunlight for at least 6 hours a day. It's best planted against a sunny wall or fence where it can receive ample sunlight, which is vital for the development of blooms and overall plant vigor. While it can tolerate some partial shade, too much shade can lead to fewer blossoms and a greater susceptibility to pests and diseases.

Temperature

Climbing roses like 'Blairii Number Two' are hardy and can tolerate a range of temperatures, but they perform best when the temperature is between 65°F and 75°F. They can survive in temperatures as low as 20°F, but you should protect them from frost to prevent damage. During hot weather, ensure they have adequate water to prevent stress from high temperatures.

Pruning

Pruning the climbing rose 'Blairii Number Two' helps maintain its shape, encourage new growth, and improve air circulation which can reduce disease risk. The best time for major pruning is during late winter or early spring before new growth begins. Remove any dead or diseased wood, and thin out crowded areas. On mature plants, some of the oldest canes can be removed at the base to rejuvenate the plant. Light pruning to shape the rose can be done throughout the growing season.

Cleaning

As needed

Soil

The Climbing Rose prefers a well-draining soil rich in organic matter with a pH between 6.0 and 7.0. A recommended soil mix includes one-third garden soil, one-third compost or well-rotted manure, and one-third peat moss or leaf mold to ensure good drainage and fertility.

Repotting

Climbing Roses, such as Rosa 'Blairii Number Two', do not need frequent repotting and are typically planted in the ground. However, if grown in containers, repotting every 2 to 4 years in early spring is recommended to refresh the soil and accommodate root growth.

Humidity & Misting

Climbing Roses prefer a moderate humidity level but are quite adaptable. The best humidity level for these roses would range from 40 to 60 percent, which is often found naturally outdoors.

Suitable locations

• Indoor

  Ensure ample light, proper watering, and good air flow for indoor Climbing Roses.

• Outdoor

  Plant in sunny spot, provide support, and ensure rich, well-draining soil.

• Hardiness zone

  5-9 USDA

Life cycle

Rosa 'Blairii Number Two' (ClBb), commonly known as Blairii No.2 climbing rose, begins its life as a dormant bare-root plant or potted specimen during early spring or late winter. After planting, it enters a vegetative stage where new shoots emerge, leaves develop, and the plant establishes a solid root system. During late spring to summer, the rose proceeds into the flowering stage, with buds forming and unfurling into large, fragrant, and often double blooms of pink or blush hues. After pollination, which may involve insects like bees, the flowers may develop into rose hips, the fruit of the rose that contains seeds for the next generation. As fall approaches, the rose starts to prepare for dormancy, ceasing flower production and conserving energy. Over winter, the plant rests, with little to no growth, until the cycle begins again with the warmth of the following spring.

  Spring-Early Summer

• The Rosa 'Blairii Number Two', commonly known as Blairii No. 2 climbing rose, is best propagated during its dormancy period, typically in late winter or early spring. The most popular method of propagation for this rose is by taking softwood cuttings. This process involves selecting healthy, new growth that has not yet hardened (characterized by a green, flexible stem), usually taken in spring or early summer. A cutting, approximately 6 to 8 inches (15 to 20 centimeters) long, is made just below a leaf node, and the lower leaves are removed. The bottom end of the cutting is then dipped in rooting hormone to facilitate root development. The cutting should be planted in a well-draining soil mix and kept in a high-humidity environment until roots have developed, at which point it can be transplanted to a permanent location.
