How to Prune Clematis in the Fall for Gorgeous Blooms

Clematis are known for adding elegance and charm to any garden with their colorful blooms. Pruning is an essential task to keep your plant healthy and blooming year after year.

But, let me warn you, you can’t just prune whenever you feel like it. So, I’m going to give you some tips on how and why fall pruning is essential for your clematis to bloom again and again.

The key is to know your clematis variety, because each group, like hydrangeas, has a different care throughout the year. Let’s now see how to prune your clematis properly in the fall!

Blooming Clematis

Pruning clematis at the right time is crucial for ensuring a healthy plant with abundant flowers year after year.

If you’re planning to prune your clematis this fall, follow these simple steps based on your plant’s group.

  • Group 1 clematis: These clematis varieties flower in late spring or early summer. Focus on tidying the plant by cutting back any dead or damaged stems. Avoid heavy pruning that could remove next year’s flower buds.
  • Group 2 clematis: These clematis varieties bloom twice—first in the spring on old wood, and again in late summer on new growth. They can be pruned more thoroughly. Remove any dead, weak, or damaged stems, but leave the old wood intact for spring blooming. Light shaping can be done to keep the plant looking neat.
  • Group 3 clematis: These bloom in late summer or fall. So, fall is the perfect time for a hard prune. Cut the stems back to about 12 to 18 inches above the ground, leaving a few strong buds. This helps the plant regrow vigorously in the spring and produce a wealth of new blooms.

If you’re not sure which group your clematis falls into, let me give you a quick and simple guide.

Clematis varieties fall into three main groups, each with its own pruning schedule. While most gardeners focus on spring or summer pruning, some types of clematis also benefit from fall pruning. Knowing which group your clematis belongs to will help guide your fall care routine.

These clematis varieties flower in late spring or early summer, blooming on old wood (last year’s growth).

Since Group 1 clematis only bloom on old stems, heavy pruning in fall or early spring can cut off the following season’s flowers. Therefore, fall pruning should be limited to removing dead or damaged stems.

Major pruning for Group 1 clematis should be done after they finish blooming in late spring. Fall is more about tidying up and ensuring the plant remains healthy through the winter months.

Popular Group 1 varieties include Clematis montana and Clematis alpina.

These clematis varieties bloom twice—first in the spring on old wood, and again in late summer on new growth. Group 2 clematis benefit from light pruning in both early spring and fall.

In the fall, you can remove dead or weak stems to tidy up the plant before winter, but avoid cutting back healthy old growth, as this could reduce spring blooms.

Focus on cleaning up the plant, encouraging a neat shape, and removing any spent blooms or stems. This prepares your clematis for a strong blooming season in the spring.

Common Group 2 varieties include Clematis ‘Nelly Moser’ and Clematis ‘The President.’

Group 3 clematis, which bloom in late summer or fall, are more tolerant of heavy pruning in the fall.

These clematis varieties only flower on new growth, so you can cut them back aggressively in late fall after their blooming season ends.

Prune the plant back to about 12 to 18 inches above the ground, making sure to leave some strong buds for next year.

This hard pruning encourages fresh, vigorous growth in the spring, leading to a fuller, healthier plant with more blooms.

Examples of Group 3 clematis include Clematis viticella and Clematis ‘Jackmanii.’

Fall pruning can help certain clematis varieties prepare for the winter, removing dead or weak growth that might not survive the colder months. It can also prevent the plant from becoming too tangled or messy, which can affect its health and vigor the following year.

Beautiful Clematis

For late-blooming clematis, fall pruning is essential for encouraging strong new growth. For others, fall pruning helps keep the plant tidy without compromising next season’s blooms.

However, it’s important to remember that early bloomers clematis should only be lightly pruned in the fall to remove dead stems. For these varieties, fall pruning should be about maintenance rather than shaping or reducing the size of the plant.

Fall pruning is particularly important for Group 3 clematis, while Group 1 and 2 varieties may only need light trimming to remove dead growth. By knowing which group your clematis belongs to, you can prune with confidence, helping your plant bloom beautifully season after season.
