How To Grow Clematis
Easy to grow, it is vigorous and disease resistant. Just prune to 18-24" in late winter or early spring. A good rule of thumb is 1" of water a week.
Clematis thrive in full sun and part shade but appreciate having their feet cool. Underplant with a shallow rooted groundcover such as Ajuga or mulch with manure, careful to keep it 4-6 inches away from the stems to avoid rot. Plant it near a shrub, where the roots would be in afternoon shade. Once it beings to grow in spring, begin training it by angling them towards a trellis or pole. Consider using fishing line to provide support for the plant.
If you've been admiring these gorgeous plants, don't hesitate to grow these beauties. You'll find them easy to grow with countless opportunities to use them in a landscape. Don't be fooled by it's delicate nature as it rapidly grows once warm weather begins in spring.

Soil: well-drained soils are essential for success with clematis. They have big, thick, fleshy, rope-like roots that also benefit from loose soils, which can make clay problematic. They do prefer neutral to slightly alkaline soils but ultimately, good drainage is far more important than "proper" pH.
Light: Full sun to part shade. The old saying for clematis is, "Feet in the shade, head in the sun," so its best if the vines get plenty of sunshine but the roots stay cool and shaded, either with neighboring plants or mulch.
Spacing: Because they are vines, spacing is not as crucial for clematis as for other woody plants. 2-3' apart should be fine in most situations.
Fertilizing: fertilizer is not necessary, but you can apply a granular rose fertilizer in early spring if desired.
Winterizing: Aside from a 2-3" layer of shredded bark mulch over the roots, no special winter care is required. Plants should be left standing over winter.
Maintenance & pruning: Prune this clematis to about 18-24" in early spring, just as the new growth begins to emerge, making your cuts above where a big, healthy bud can be seen. This may seem extreme, but creates a lush display of flowers from stem to tip. As the plant becomes more mature, it will create more and more growth to recover from the yearly prune, giving you the coverage you desire.
