Garden plant of the moment: Clematis

Garden plant of the moment: Clematis

You say clem-ay-tis, I say clem-ah-tis; whatever you pronounce it, no garden should be without one of these beautiful climbing plants. With so many different clematis varieties available, there’s one in flower just about every month of the year, and right now, it’s the turn of the spring-flowering clematis to dazzle with their display of gorgeous blooms.


How to plant a clematis

There are a few golden rules to follow when planting a clematis:

  1. All clematis prefer to keep their feet cool, so always plant with the roots in shade. You can also put bricks or slate around the base of the clematis to shade the roots. 

  2. Plant your clematis deep, so that the point at which the stem emerged from the compost in its pot is at least 15cm (6in) below ground level. If your clematis develops wilt (a fungal disease that clematis are prone to), planting deep will help it to re-grow from the portion of the stem that is below the ground.

  3. Clematis appreciate fertile soil, so put a shovelful or two of compost in the planting hole before planting your clematis.

  4. Water your clematis regularly in its first year after planting, especially during dry periods.


How to prune a spring-flowering (group 1) clematis

Clematis are divided into three groups according to when they flower, and spring-flowering clematis falls into group 1. Unlike the other two groups, group 1 clematis don’t necessarily need to be pruned every year. However, the larger varieties, especially Clematis Montana and Clematis armandii, may need pruning to keep them from getting too large. If you need to prune your spring-flowering clematis to keep it to size, wait until after it has finished flowering, then trim over-long shoots, cutting back to a pair of healthy buds. To renovate an old, congested group 1 clematis, cut back all stems almost to the base, then feed, mulch and water regularly.
