Soil and Growing Condition Tips
Soil for Clematis should not be too acidic but alkaline soil is fine. Impoverished soil near a wall or under a hedge should be improved with plenty of humus before planting. Sandy soil looses moisture quickly and also needs humus adding.
All clematis will grow better if the roots are kept cool. Plant a bit deeper than the soil level in the pot where they were grown and cover the roots area with a tile, rock or mulch.
Large flowered varieties will have stronger colours if the flowers grow in light shade.
Use a good Foliar feed every 7-10 days and a good root drenching weekly.
Types of Clematis Support
All clematis even the herbaceous varieties need some support. The easiest support is often other plants with matching characteristics – heather for small macropetala types or a tree for the more robust viticella varieties.
Walls are fine as long as the mortar and brickwork is sound for a network of wire. Clematis montana can cover a large wall quickly.
Trellis itself needs to be securely attached to battens but can be attractive when cloaked in Clematis or on it’s own in winter.
Archways, tripods and obelisks look great when covered with a climber such as clematis. Similarly pergolas can have both climbing roses and clematis co-existing.
Try a pillar made from a length of Oak or hardwood to train your clematis because you are bound to want to grow more once you start.

Cultivating Clematis All Year Around
- Pot up small clematis plants and grow them on until large enough to plant in their final positions.
- When planting clematis, choose a position in sun or semi-shade and plant the climber deeply in moist, fertile, well drained soil.
- Position the top of the rootball at a depth of at least 3″ below soil level to encourage new shoots to form from the base of the plant and prevent wilt.
- Clematis dislike soils that are particularly wet or dry. Soil can be improved by the addition of plenty of well rotted manure or garden compost.
- Train clematis plants onto a suitable support such as trellis, wires or a freestanding climbing frame.
