English Rose Rosa Charles Rennie Mackintosh = 'Ausren' (S)

Water

The English Rose 'Charles Rennie Mackintosh' requires consistent moisture, so water it deeply every week, providing about 1 to 1.5 gallons of water each time. During hot or dry weather, you may need to water twice a week. Avoid overhead watering to prevent disease; instead, water at the base of the plant. Always check the soil before watering; it should be moist but not waterlogged. Reduce watering in the winter months when the plant is dormant.

Light

The English Rose 'Charles Rennie Mackintosh' thrives in full sunlight. It requires at least 6 hours of direct sunlight a day to produce robust growth and abundant blooms. The ideal spot for this rose would be an area that is sunny from morning to mid-afternoon, with some light shade during the hottest part of the day to protect the blooms from intense heat.

Temperature

The English Rose 'Charles Rennie Mackintosh' prefers a temperature range between 40°F and 90°F but can survive brief periods outside of this range. The ideal growing conditions are in a temperate climate with mild to warm days. Avoid exposing the rose to temperatures below 20°F, as this may damage the plant, and sustained heat above 90°F may stress it and reduce bloom quality.

Pruning

Pruning the English Rose 'Charles Rennie Mackintosh' is essential to maintain its shape, encourage healthy growth, and promote abundant flowering. Prune in late winter or early spring, removing dead or damaged wood and thinning out crowded branches. Aim to create an open, vase-like structure. Deadhead spent flowers during the blooming season to encourage more blooms.

As needed

Soil

The best soil mix for the English Rose 'Rosa Charles Rennie Mackintosh' should be well-draining with plenty of organic matter, such as compost or well-rotted manure. Consider adding bone meal for phosphorus and to encourage strong root development. The ideal soil pH for this plant is between 6.5 and 7.0, which is slightly acidic to neutral.

Repotting

English Roses like 'Rosa Charles Rennie Mackintosh' do not need to be repotted often as they are typically planted directly into the ground. If grown in a container, they should be repotted when the plant becomes root-bound or after several years when the soil nutrients have been depleted.

Humidity & Misting

English Roses such as 'Rosa Charles Rennie Mackintosh' prefer outdoor conditions and thus do not require specific humidity levels. However, roses generally thrive in areas with average humidity and good air circulation to decrease the incidence of diseases like powdery mildew and black spot.

Suitable locations

• Indoor

  Provide ample sunlight, regular watering, and good air circulation.

• Outdoor

  Plant in full sun, enrich soil with organic matter, ensure good drainage.

• Hardiness zone

  5-9 USDA

Life cycle

The Rosa 'Charles Rennie Mackintosh' begins its life cycle as a dormant bare-root plant or as an established plant in a container. Once planted, it enters a growth phase where the roots establish in the soil and shoots begin to develop. The plant then enters a vegetative stage, where leaves and stems grow until it reaches maturity. In the flowering stage, typically late spring through summer, buds form and bloom into pale pink roses with a delicate fragrance. After pollination, if it occurs, the plant may produce rose hips (fruit) which contain seeds. Finally, the plant enters a period of dormancy in the late autumn and winter months, conserving energy to restart the cycle in the following spring.

Propogation

• Propogation time

  Late winter to early spring

• The Rosa Charles Rennie Mackintosh, commonly known as the 'Charles Rennie Mackintosh' rose, is most commonly propagated through softwood cuttings. This process typically takes place in the early parts of the growing season, often late spring to early summer, when the plant's new growth is still soft and flexible. Cuttings should be about 6 inches (roughly 15 cm) in length and ideally include a couple of leaves. The lower end is dipped in rooting hormone to encourage root development and then the cutting is planted in a moist potting mix, ensuring high humidity and indirect light until it establishes roots. To enhance root growth and increase the chances of success, you can provide bottom heat of about 70 to 75 degrees Fahrenheit (21-24 degrees Celsius). It usually takes several weeks for the cuttings to root, after which they can eventually be transplanted to their permanent location.
