How to Grow Beautiful Clematis Vine
Location and soil
To maximize flower production, plant your clematis in full sun. Though most varieties will grow in half-day sun, they won’t produce as many blooms. Clematis thrives in moist, well-drained soil that isn’t too acidic. You’ll want to plant the roots several inches deep (about 4 inches). Clematis can grow in containers or in the ground.
Water them regularly, especially during the heat of the summer. If you feel that the soil has gone dry, water generously but make sure you don’t end up flooding the plant. To help retain moisture and keep the soil cool, try adding mulch or bark around the plant.
Clematis vine benefits tremendously from regular fertilizing. Fertilize your soil in the Spring with a low-nitrogen fertilizer. After that, you can fertilize with a 10-10-10 fertilizer every month until Fall.
They need support. You can place them against a wall, on a fence, over an arbor or pergola. chicken wire, trellis, or trees (the vine is gentle and won’t choke a tree). Make sure there is something for the tiny tendrils to grab onto.
Clematis is not a plant you want to neglect! Pruning will greatly increase the vine’s vitality and lifespan. Deadheading old stems will promote regrowth and encourage your buds to bloom beautiful flowers. If your clematis sends up most of it’s new growth from the base of the plant, you know that it will flower on current year vines. These plants can simply be cut back each year in early spring, to a height of 12-18”. For clematis that produce most of their new growth on last year’s vines, limit your pruning to maintaining the desired shape and removing dead or weak stems. The best time to prune these plants is late summer, right after they bloom. You won’t need to do any pruning for the first year or two, so you’ll have time to see how the plant grows and then prune your vines properly.
Clematis can fall prey to a disease called Clematis Wilt. If you notice that entire branches are turning black, then your clematis has likely been infected with this disease. There’s a simple fix: remove the black wood promptly by cutting it down until you reach healthy wood.
