Clematis ‘Jescot’ offers unique and vibrant blooms that can transform vertical spaces. This variety is admired for its aesthetic appeal, enhancing trellises, arbors, and other garden structures. Understanding its specific needs helps cultivate a healthy plant that delivers abundant flowering. Consistent care ensures gardeners can appreciate its distinctive charm.
Characteristics of Clematis ‘Jescot’
Clematis ‘Jescot’ is a large-flowered hybrid known for its eye-catching blooms. These typically reach 4 to 8 inches in diameter, often showcasing rich, vibrant hues like purple, pink, or blue. The plant exhibits a vigorous climbing habit, making it an excellent choice for vertical garden accents. It typically reaches 8 to 12 feet tall, with a spread varying by support and pruning. Its bloom period spans late spring through early summer, with a potential for a second flush in late summer or early autumn.
Planting and Site Selection
Successful establishment of Clematis ‘Jescot’ requires careful site selection and soil preparation. This clematis thrives in ample sunlight, ideally receiving at least six hours daily for optimal flowering. While foliage and flowers prefer sun, roots need cool, shaded conditions, achieved by planting low-growing perennials nearby or applying mulch. Protecting the plant from strong winds is also beneficial to prevent physical damage.
Clematis ‘Jescot’ performs best in well-drained soil rich in organic matter. A soil pH between 6.0 and 7.5 is suitable. Before planting, amend heavy or sandy soils with compost or well-rotted manure to improve fertility and drainage. For very heavy clay soils, adding perlite or sand further enhances drainage, preventing waterlogging.
Dig a hole wider and deeper than the root ball, around 18 inches in diameter and depth. Position the clematis so the top of its root ball is 2 to 4 inches below the soil surface. This deeper planting encourages multiple stems from below ground, aiding recovery from issues like clematis wilt. Backfill the hole with amended soil, firming it around the roots, and water thoroughly to settle the soil.
Ongoing Care and Cultivation
Maintaining Clematis ‘Jescot’ involves consistent watering, feeding, support, and pruning. These measures promote vigorous growth and abundant blooms.
Watering and Feeding
Clematis ‘Jescot’ requires consistent moisture. Newly planted clematis should be watered deeply two to three times per week for the first few weeks. Once established, the plant needs about one inch of water per week, adjusted for weather. Water at the base to keep foliage dry, preventing fungal diseases. A 2-3 inch layer of organic mulch around the base helps retain soil moisture and keeps roots cool.
Clematis benefit from regular fertilization to support abundant flowering. Begin feeding in early spring as new growth emerges. A low-nitrogen fertilizer (e.g., 5-10-5) or a balanced fertilizer (e.g., 10-10-10) is suitable, as excessive nitrogen promotes leafy growth over flowers. Fertilizers designed for roses or tomatoes, higher in potassium, also work well. Fertilize monthly or every four to six weeks throughout the growing season until mid-to-late September, or use a slow-release granular fertilizer once in spring.
Providing Support
As a vigorous climbing vine, Clematis ‘Jescot’ requires sturdy support. Trellises, obelisks, arbors, fences, or robust shrubs and trees can serve this purpose. The plant’s petioles twine around supports, allowing it to ascend. Guide and tie new shoots to the support as they grow, encouraging the vine to climb. This training ensures the plant is well-distributed, maximizing light exposure for flowering and improving air circulation.
Pruning Clematis ‘Jescot’
Pruning is important for Clematis ‘Jescot’ to encourage prolific blooming and maintain plant health. This large-flowered hybrid blooms on new wood, falling into Pruning Group 3. Primary pruning occurs in late winter or early spring, typically February to March, before new growth begins.
During this annual prune, cut all stems back to about 12 to 18 inches (30 to 45 cm) from the ground, just above a strong, visible pair of buds. This pruning encourages vigorous new shoots from the base, which will bear the season’s flowers. Removing dead, weak, or tangled stems also improves the plant’s structure and prevents disease.
Addressing Common Issues
Clematis ‘Jescot’ may encounter common issues like diseases and pests. Early identification and intervention help maintain plant health.
Clematis wilt is a fungal disease that can affect clematis, particularly large-flowered hybrids. Symptoms include sudden wilting and blackening of stems and leaves. If suspected, promptly cut back all affected stems to healthy tissue, even to ground level. Dispose of infected plant material away from the garden, as the fungus can persist. Roots typically survive, and the plant often regrows from the base in subsequent seasons.
Powdery mildew appears as a white, powdery coating on leaves and stems. It is exacerbated by warm, humid conditions and poor air circulation. To manage it, ensure adequate spacing and avoid overhead watering, especially in the evening. Removing infected leaves helps limit spread. In severe cases, fungicides labeled for powdery mildew can be applied.
Pests like aphids and slugs might affect Clematis ‘Jescot’. Aphids are small insects that cluster on new growth, causing stunted foliage. A strong spray of water can dislodge them, or insecticidal soap/neem oil can be used. Slugs cause irregular holes in leaves, especially on young shoots. They are most active at night and can be controlled by hand-picking, using slug baits, or creating physical barriers like copper strips or diatomaceous earth.
