Their elegance, color, variety and exquisite flower shapes have catapulted clematis to the top of the climbers' charts. Plant them with care and you will enjoy these superstars for many years to come.
When to Start: Early fall
At Its Best: Depends on variety
Time to Complete: 1-12 hours
First, dig plenty of organic matter into the soil. If growing clematis up a wall or fence, position the plant 18 inches away from it. Dig a hole about 12 inches deep, fork over the base, and add some fertilizer to the excavated soil.
Clematis are best planted deeply, so that if clematis wilt strikes, the plant will survive. Place the clematis in its pot in the hole, and lay a stake or string over it to check that the lower stems will be 2 inches beneath the soil surface when it's planted.
After watering thoroughly, remove the clematis from its pot and plant it in the hole. Carefully backfill with the fertilized soil, pushing it gently between the brittle stems with your fingers and making sure there are no air pockets as you go.
Gently firm the soil with your foot and tie stems to an obelisk or other support. Water in well. Add a thick mulch of organic matter, keeping it clear of the stems. Continue to water regularly until the plant is established.
