Planting Instructions

Clematis grown in containers are a beautiful way to add height to a patio or courtyard garden. Choose a container 18" (45cm) approx. diameter for a single clematis plant plus support. For larger containers consider planting two or more plants per container. When choosing a container, Terracotta or wood are the best materials.


Alternatively, choose a host plant and dig a hole about 18 inches (45cm) deep.

  1.  Bury the clematis root crown 2.5" (5cm) below soil surface.
  2. Loosen out the clematis roots prior to planting.
  3. Use loam based compost such as John Innes No. 3 or well-rotted garden compost.
  4. To aid drainage provide a layer of small stones or pea gravel at the bottom of the hole/container.
  5. Finally, plant low growing plants at the base of the clematis to provide shade for the roots.
