Clematis Clematis 'Ken Donson' (EL)

Water

The Clematis, also known as the Queen of the Vines, should be watered deeply but infrequently to encourage a strong root system. During the growing season, water the plant once a week with about 1 gallon of water, ensuring that the soil is thoroughly moistened. Increase the frequency to twice a week during periods of extreme heat or drought. It's important to avoid overhead watering to prevent fungal diseases; instead, apply water directly to the base of the plant. During the winter months, reduce watering as the plant does not require as much moisture.

Light

Clematis thrive best in a location where they receive at least six hours of sunlight a day. They prefer their roots to be in the shade while the top of the plant is exposed to sunlight, so choosing a spot with morning sun and afternoon shade or dappled sunlight throughout the day is ideal. Ensure that the Clematis is planted in a position where it won't be overshadowed by other plants as it climbs.

Temperature

Clematis prefer a moderate climate with temperatures ranging between 55°F and 75°F. They can tolerate temperatures as low as 20°F and as high as 90°F for short periods, but for optimal growth, keeping them within the moderate range is beneficial. The plant should be protected from extreme cold winds and excessive heat to ensure healthy growth.

Pruning

Clematis should be pruned to promote healthy growth and to maintain the desired shape. Group 2 Clematis like 'Ken Donson' typically require light pruning in early spring before they start actively growing. Prune just above a pair of healthy buds, removing any dead or weak stems. This will also help encourage new growth and larger blooms for the upcoming season. The best time for pruning Group 2 Clematis is after the first bloom, to shape the plant and encourage a second flowering.

Cleaning

As needed

Soil

The best soil mix for Clematis, commonly referred to as clematis vines, should be well-draining, fertile, and moisture-retentive. It should contain a mixture of loam, compost, and well-rotted manure to provide essential nutrients. The soil pH should ideally be neutral to slightly alkaline, between 6.5 to 7.5, for optimal growth.

Repotting

Clematis vines typically do not need to be repotted often as they are usually grown outdoors in the ground. However, if grown in containers, they may be repotted every 2 to 3 years to prevent them from becoming root-bound and to replenish soil nutrients.

Humidity & Misting

Clematis vines thrive in outdoor conditions where the humidity is natural and not too high. They do not require specific humidity levels indoors, as long as the air is not excessively dry. It's important to focus more on adequate watering and drainage than on maintaining specific humidity levels.

Suitable locations

• Indoor

  Plant in large pot with support, ample light, and good air flow.

• Outdoor

  Plant in sun to part shade; provide support for climbing.

• Hardiness zone

  4-9 USDA

Life cycle

The life cycle of Clematis 'Ken Donson' begins with germination, where the plant's seeds sprout in moist, well-drained soil, typically in spring or early summer. The seedlings then develop into juvenile plants with a robust root system and foliage, climbing or sprawling as they mature. This clematis variety enters a vegetative stage, producing long, woody vines and large leaves used for climbing and photosynthesis. It reaches the flowering stage in late spring to early summer, displaying prominent, showy flowers that attract pollinators. After pollination, the plant forms seed heads, which disperse seeds for reproduction. Each year, Clematis 'Ken Donson' will enter a period of dormancy during colder months, only to re-emerge with new growth and repeat the cycle as the weather warms.

Propogation

• Propogation time

  Spring-Early Summer

• Clematis 'Ken Donson', commonly referred to as Clematis, is most effectively propagated by layering. This propagation method usually takes place in the spring. To layer Clematis, a healthy, flexible stem is bent to the ground and a section midway along its length is covered with soil while both ends remain above the ground. Securing the stem to the soil can help maintain contact, and the section beneath the soil should be notched or slightly wounded to encourage rooting. Over time, roots will form at the point of soil contact, and once a good root system has developed, the new plant can be severed from the parent and transplanted elsewhere. This process allows the Clematis to maintain varietal characteristics and ensures a clone of the parent plant.
