How to Care for your Clematis

Clematis have long been known as “queen of the climbers” and for good reason.  No other perennial vine offers the versatility in form and colour, especially with the hybridizing and access to varieties of today. 

The easy growing clematis has become a plant that every gardener can enjoy.

Basic Care

  • plant in fertile, well drained alkaline (not acidic) soil; add Dolomitic Lime powder to raise the pH of the soil
  • a full sun location will ensure maximum blooming, however, clematis will also perform well in partial shade
  • when planting, the top of the rootball should be 3” below garden level to encourage deep roots
  • the base of the vine and surrounding soil must be shaded.  Plant a low shrub, tall perennial or annuals in front to keep the base of the plant cool
  • clematis have a ‘high metabolism’ and need to be fed regularly with a high phosphorous (middle number) plant food
  • removing old blooms will encourage it to bloom even more
  • clematis need something to climb on/around, like a wooden trellis, arbour, fence or even a tree!
