Clematis plants are popular and beautiful additions to any garden. They are known for their colorful and showy flowers that bloom throughout the year. But, to help your clematis plant thrive, you need to know how to prune it. Pruning is essential for keeping the plant healthy and promoting new growth. In this article, we will discuss how to properly prune a clematis plant.

Clematis plants are divided into three groups:

Group 1: Flowers in early spring on last year’s growth.

Group 2: Flowers in late spring to early summer on old and new growth.

Group 3: Flowers in summer to fall on new growth.

The pruning technique for each group is different. Let’s look at each group and discuss their pruning needs.

Group 1

Group 1 clematis flowers on last season’s growth and should be pruned after flowering. The aim of pruning is to tidy up the plant and remove dead and damaged stems. Group 1 clematis plants only require a light trim, removing up to one-third of the length of the plant’s stems.

If you are new to pruning clematis, avoid pruning too hard, as it may kill the plant.

Gently cut back all dead and damaged stems, leaving the healthy stems intact. The best time to prune group 1 clematis is immediately after flowering.

Group 2

Clematis in Group 2 blooms on old wood and new growth. Prune Group 2 clematis in early spring to establish its shape. You can also prune lightly after the first flush of flowers to encourage a second flush.

Prune all dead and damaged stems and remove any stems that are lying on the ground. Keep the plant to a tidy framework, allowing stems to grow upwards and adding support if necessary. Aim to cut back to a large, healthy pair of buds on each stem.

For Group 2 clematis, prune in early spring by removing all dead and damaged stems and cutting back the remaining stems to a healthy pair of buds.

Group 3

Clematis in Group 3 blooms on new growth. They are the easiest to prune and can be cut back hard to six inches from the ground in late winter or early spring.

Prune clematis Group 3 hard each year to promote new growth and to encourage the plant to grow upwards. Cut all stems down to a height of six inches from the ground. You can also gently prune the plant throughout the growing season to remove any dead flowers or damaged stems.

Pruning Tips

When pruning clematis, use a sharp pair of pruning shears, and always sanitize the equipment with rubbing alcohol or bleach between cuts. This will prevent the spread of any plant diseases.

Always prune your clematis plant according to its growth habit. This will ensure that you get the most blooms possible.

Conclusion

Clematis plants are beautiful and easy to grow in any garden. Knowing how to prune them is essential for their health and growth. Remember to prune according to the plant’s growth habit, and sanitize your pruning tools to prevent the spread of diseases. Happy pruning!
