Clematis Clematis The Countess of Wessex = 'Evipo073' (EL)

Water

The Clematis, commonly known as 'The Countess of Wessex', prefers a consistent watering schedule to maintain moist but not saturated soil. Water the plant deeply once a week with about 1 gallon of water, increasing frequency during hot, dry periods to twice a week. Avoid overhead watering to prevent fungal diseases; instead, water at the base to keep the leaves dry. During the winter months, reduce the amount of water, but do not let the soil dry out completely. Ensure good drainage to prevent waterlogging, which can cause root rot.

Light

Clematis 'The Countess of Wessex' thrives best in a location that offers full sun to partial shade. The ideal spot would provide around 6 hours of sunlight a day, with some protection from the intense afternoon sun. Planting near a structure that allows for climbing, such as a trellis or fence, can also ensure that the plant receives adequate light as it grows.

Temperature

For the Clematis 'The Countess of Wessex', the ideal temperature range is between 50°F and 70°F. This plant is hardy and can withstand temperatures down to about 20°F but should be protected from extreme cold. The maximum temperature should not exceed 90°F for extended periods as extreme heat can be detrimental to the plant's health.

Pruning

Pruning Clematis 'The Countess of Wessex' encourages strong growth and flowering. It is a Group 2 Clematis, which means it should be lightly pruned in early spring to remove any dead or weak stems. Right after the first flush of blooms in the early summer, prune lightly again to shape the plant and promote new blossoms. The best time for the main pruning is when the buds swell but before they open.

Cleaning

As needed

Soil

Clematis 'The Countess of Wessex' thrives in a well-draining soil mix with plenty of organic matter. A mix of loamy soil, compost, and coarse sand or perlite can create a suitable environment. The pH level should be slightly alkaline to neutral, around 7.0 to 7.5. Regular mulching helps maintain soil moisture and temperature.

Repotting

Clematis 'The Countess of Wessex' should be repotted every 2 to 3 years to replenish nutrients in the soil and accommodate root growth. Larger containers should be used each time to allow for adequate space for the roots to expand.

Humidity & Misting

Clematis 'The Countess of Wessex' prefers a moderate humidity level, similar to the outdoor environment in temperate regions. While specific humidity levels are not crucial, avoiding excessively dry air will support its health and growth.

Suitable locations

• Indoor

  Provide bright indirect light and support for climbing.

• Outdoor

  Plant in sun to partial shade; train on structures.

• Hardiness zone

  4-9 USDA

Life cycle

The life of the Clematis 'The Countess of Wessex' ('Evipo073' EL) begins with germination, where the plant emerges from a small seed typically after exposure to a period of cold, mimicking winter conditions. Following germination, the seedling develops into a young plant with a few leaves, and the root system starts to establish in the soil. As it matures, it enters a vigorous growth phase, characterized by the development of long, climbing vines and lush foliage. During the blooming stage, from late spring to early autumn, the plant produces large, rounded, creamy-white flowers with a delicate pale green bar. After pollination, often by insects attracted to the blooms, seed heads form and, once matured, disperse seeds to repeat the cycle. As a perennial, the Clematis 'The Countess of Wessex' dies back to its woody stem structure in winter, to regrow from this framework in the following spring.

Propogation

• Propogation time

  Spring to Summer

• Clematis The Countess of Wessex 'Evipo073' (EL), commonly known as Clematis, is best propagated in spring when the plant is beginning to grow actively. The most popular method is by taking softwood cuttings which involves selecting a healthy piece of stem about 4 to 6 inches (10 to 15 centimeters) long from the current year’s growth. The leaves near the bottom of the cutting should be removed, and the cut end dipped in rooting hormone. The cutting is then planted in a pot with well-draining soil, ensuring that the soil remains moist but not waterlogged. Covering the cutting and pot with a plastic bag can help maintain humidity. It should be placed in indirect light until roots have developed, which can be checked periodically by gently tugging on the cutting; if there's resistance, roots are likely forming. After strong root growth is established, the new Clematis can be transplanted into the garden.
