Climbing Rose Rosa 'Notre-dame de Calais' (Cl)

Water

The climbing rose 'Notre-Dame de Calais' should be watered deeply once a week, ensuring that the soil is thoroughly moistened to a depth of about 18 inches. During hot or dry spells, the frequency may need to increase to twice a week. You should provide the climbing rose with approximately 1 to 1.5 gallons of water per plant during each watering session. Avoid overhead watering to prevent leaf diseases, and instead water at the base of the plant to keep the roots well-hydrated.

Light

Climbing roses like 'Notre-Dame de Calais' thrive in full sun conditions, requiring at least 6 to 8 hours of direct sunlight each day. The ideal spot for planting is one that receives morning sunlight, which helps to dry the dew on the leaves and prevent fungal diseases. Partial shade is acceptable, especially in hotter climates, but too much shade can lead to fewer blooms and a weaker plant.

Temperature

The climbing rose 'Notre-Dame de Calais' prefers a temperate range with ideal temperatures between 65°F to 75°F. It can withstand minimum temperatures down to about 20°F, making it suitable for USDA hardiness zones 5 through 9. These roses can survive maximum temperatures well into the 90s°F, though they may require additional watering during extreme heat.

Pruning

Pruning climbing roses like 'Notre-Dame de Calais' is essential to promote healthy growth, increase air circulation, and encourage more blooms. Pruning should be done in late winter or early spring, before new growth starts. Remove any dead or diseased wood, and thin out overcrowded areas, cutting back to outward-facing buds. Aim to do a more significant pruning every few years to rejuvenate older plants.

Soil

Rosa 'Notre-Dame de Calais', commonly known as the climbing rose, thrives in loamy, well-draining soil with a pH between 5.5-7.0. The best soil mix is one-third garden soil, one-third well-rotted compost, and one-third sharp sand or perlite for drainage. Regular application of organic matter will help maintain soil health.

Repotting

Climbing roses like Rosa 'Notre-Dame de Calais' are typically not repotted as they are grown outdoors in the ground. If grown in large containers, they can be repotted every few years to renew the soil or when the plant outgrows the current pot.

Humidity & Misting

Climbing roses, such as Rosa 'Notre-Dame de Calais', are adaptable to a wide range of humidity levels. However, they prefer moderate humidity and good air circulation around the foliage to prevent disease.

Suitable locations

• Indoor

  Provide bright light, prune, and ensure good air flow.

• Outdoor

  Plant in full sun, ensure good soil, and allow space for growth.

• Hardiness zone

  5-9 USDA

Life cycle

Rosa 'Notre-dame de Calais' (Cl), commonly known as the Notre-Dame de Calais Climbing Rose, begins its life cycle when a seed germinates or more commonly, when a cutting from a mature plant takes root. The plant then enters a vegetative phase, where it develops a strong root system and sends up shoots that will become canes. As the canes mature, they grow longer and develop thorns, and the plant forms leaves that engage in photosynthesis to fuel further growth. Following the vegetative stage, the climbing rose enters the blooming phase, typically in late spring to early summer, where it produces its distinctive fragrant flowers ranging from deep pink to pale pink hues. After pollination, which is often facilitated by insects, the flowers develop into rose hips (seed pods) if conditions permit, which contain seeds for potential reproduction. Over time, the climbing rose may enter a period of dormancy during colder months, only to re-emerge with new growth and repeat its life cycle in the following growing season.

Propogation

  Spring-Early Summer

• The Rosa 'Notre-Dame de Calais' (Climbing Rose) can be propagated most commonly through softwood cuttings. This method is preferred due to its relative simplicity and effectiveness. During late spring to early summer, when the plant's new growth is still flexible, take cuttings about 6 to 8 inches (15 to 20 centimeters) in length, cutting just below a leaf node. Remove the leaves from the lower half of the cutting and dip the cut end in rooting hormone to encourage root growth. Then, insert the cutting into a pot filled with a mixture of perlite and peat moss to provide aeration and moisture retention. The pot should be kept in a warm place with indirect light and covered with plastic to maintain high humidity. Roots typically develop within a few weeks, after which the new plants can eventually be transplanted into the garden.
