What Do You Do With Clematis After Flowering

What you do with clematis after flowering is all about timing and knowing which type of clematis you’re growing.

If you’ve been wondering what to do with clematis after flowering, the short answer is that it depends on whether your plant blooms in spring or summer.

Get this right and you’ll enjoy a second flush of blooms on many varieties, and you’ll keep your vine healthy and vigorous.

In this post, we’ll walk through exactly what do you do with clematis after flowering for each group, the best pruning techniques, and the simple feeding routine that makes all the difference.

Let’s dig in.

What to Do With Clematis After Flowering: The Pruning Basics

The first thing to understand about what to do with clematis after flowering is that there are three main pruning groups.

Clematis are categorized into Group 1, Group 2, and Group 3, and each one has a different flowering time and a different pruning need.

If you prune at the wrong time, you could accidentally cut off next year’s flower buds.

So let’s break down what to do with clematis after flowering by group.

Group 1 Clematis: Early Spring Bloomers

Group 1 clematis bloom in early spring on old wood, which means the flower buds formed during the previous growing season.

When you’re deciding what to do with clematis after flowering, these types need virtually no pruning at all.

You can simply remove any dead or damaged stems right after the blooms fade.

What to do with clematis after flowering for Group 1 is mostly about tidying up, not cutting back hard.

If the plant has outgrown its space, you can do a light shaping trim right after flowering ends.

This is the perfect time because the plant is about to start its new growth cycle.

Group 2 Clematis: Large-Flowered Early Summer Bloomers

Group 2 clematis are the big-flowered hybrids that put on a spectacular show in early summer.

These are the ones that often bloom again in late summer if you treat them right.

What to do with clematis after flowering for Group 2 is a light pruning after the first flush.

Cut back the stems that have just finished blooming to a pair of strong buds lower down the stem.

This simple trick encourages the plant to send out new growth that will produce a second round of flowers.

You’ll also want to remove any dead or weak stems while you’re at it.

This type of gentle pruning keeps the plant compact and promotes more branching.

Group 3 Clematis: Late Summer and Fall Bloomers

Group 3 clematis bloom on new wood that grows in the current season.

So what to do with clematis after flowering for these varieties is quite different.

These plants don’t need much attention right after they bloom because their old growth is simply replaced each spring.

Instead, you’ll do a hard prune in late winter or early spring.

But there is something you can do after flowering for Group 3 types: you can remove the spent flower heads to keep the plant looking neat.

This is more about appearance than plant health.

Feeding and Watering Clematis After Flowering

Beyond pruning, what to do with clematis after flowering includes giving your plant a little nourishment.

After a heavy bloom, clematis have used up a lot of energy.

A balanced fertilizer applied after flowering will help replenish those nutrients.

Use a slow-release fertilizer or a liquid feed that’s high in potassium to encourage more flowers.

Water deeply after feeding so the nutrients reach the roots.

Mulching around the base of the plant is also a smart move.

A layer of organic mulch will keep the roots cool and retain moisture.

Just make sure to keep mulch away from the stems to prevent rot.

Deadheading Clematis for More Blooms

Deadheading is another key part of what to do with clematis after flowering.

When the flowers fade and start to turn brown, simply snip them off just above the first pair of healthy leaves.

This stops the plant from putting energy into seed production.

Instead, that energy goes into producing more flowers or building strong roots.

For repeat-blooming clematis, deadheading is essential to encourage that second flush.

It’s a quick task that pays off big in the garden.

Supporting and Training New Growth

After flowering, your clematis will start pushing out fresh, vigorous growth.

Part of what to do with clematis after flowering is to guide that new growth onto your trellis or support.

Gently tie in the new stems while they’re still flexible.

This prevents them from becoming a tangled mess.

It also helps the plant get better air circulation, which reduces the risk of fungal diseases.

Check your ties regularly and loosen them as the stems thicken.

When Not to Prune Clematis After Flowering

Knowing when to leave your clematis alone is just as important as pruning.

If your clematis is a spring bloomer and you prune it in the fall, you’ll remove next year’s flower buds.

So what to do with clematis after flowering in the fall for these types is simple: don’t prune.

Let the plant stand through winter.

The old seed heads can actually add interest to the winter garden.

And many gardeners find that leaving the growth intact helps protect the crown from frost.

You can always clean things up in early spring if needed.

Dealing with Wilting and Disease After Flowering

Sometimes what to do with clematis after flowering involves damage control.

Clematis wilt is a fungal disease that can cause stems to collapse suddenly.

If you see a stem wilting after flowering, cut it back to healthy growth immediately.

Dispose of the infected material in the trash, not the compost pile.

Good air circulation is your best defense, so thin out crowded stems.

Always water at the base of the plant, not over the foliage.

This helps keep the leaves dry and reduces disease pressure.

So, What Do You Do With Clematis After Flowering?

What you do with clematis after flowering depends entirely on the type you have.

For spring-blooming Group 1 varieties, you only need light tidying after the flowers fade.

For early summer Group 2 varieties, a light pruning after the first flush will encourage a second bloom.

And for late-blooming Group 3 varieties, just remove spent blooms and save the hard pruning for late winter.

Feeding and watering after the bloom period is always a good idea.

Deadheading helps promote more flowers on repeat-blooming types.

Supporting new growth keeps the plant tidy and healthy.

And knowing when to leave your clematis alone can be just as important as knowing when to prune.

Armed with this guide, you’ll know exactly what to do with clematis after flowering, and your vine will reward you with lush growth and beautiful blooms year after year.

Happy gardening.
