What are the best growing conditions for clematis?
Although clematis are low maintenance plants, getting the conditions right is key to success when learning how to grow clematis.
How much light do clematis need?
Clematis thrive in full sun to partial shade, but they prefer their roots to stay cool.
What kind of compost do clematis need?
Clematis thrive in fertile, moist, well-drained soil that is neutral to slightly alkaline, though they can adapt to various types.
Can clematis be grown in pots?
Yes, clematis can be grown in pots (best for compact varieties), however, clematis in containers have a restricted root run so won’t spread as far and may need more regular care. If you can get them in the ground, do it!
Do clematis need support?
Clematis are climbing plants so they need support to climb vertically. What’s great about this is depending which kind of structure you pick, you can train clematis to
Ideal types of support clematis are:
-
A trellis: Attached to a fence provides a sturdy, vertical surface for clematis to climb, making it perfect for covering boundaries with lush foliage and colourful blooms.
-
Obelisks: Obelisks offer a compact, freestanding structure that’s ideal for training clematis in pots or borders, creating an eye-catching focal point.

Pergolas: Pergolas are perfect for more vigorous clematis varieties, allowing them to climb overhead and create a stunning canopy of flowers for shaded seating areas. Decorating pergolas with climbing plants will create a beautiful focal point in any garden.
Do clematis need feeding?
Clematis benefit greatly from regular feeding to support their fast growth and heavy blooming. Using a specific clematis feed can encourage vigorous growth throughout the season. But, avoid high-nitrogen fertilizers, which can produce excessive leaves and fewer flowers.
