Trumpet vine · Campsis radicans

Why is my trumpet vine looking leggy?

A leggy trumpet vine has long, bare stems with leaves only at the very tips. This is almost always a sign that the plant is reaching for more light.

Check these first

  1. Observe if the plant is leaning toward a specific light source.
  2. Check if the vine has a sturdy structure to climb.
  3. Look for signs of overcrowding from nearby shrubs.

Likely causes

  1. Insufficient light

    Most likely

    How to tell: The stems are thin and stretched out with large gaps between the leaves. The plant is leaning heavily toward the nearest light source.

    What to do: Increase the amount of direct sun the plant gets. If it is growing against a wall, ensure the wall is not casting a permanent shadow.

  2. Lack of support

    Possible

    How to tell: The vine is sprawling on the ground or drooping because it has nothing to climb. The stems look stressed and uneven.

    What to do: Provide a sturdy trellis, fence, or arbor for the vine to climb. Secure the main stems to the support using soft garden ties.

When to worry

It is normal for the base of an old, woody trumpet vine to lose some leaves. It is only a problem if the entire vine looks sparse and weak.

Stopping it coming back

Train your vine onto a strong support system early and keep it in full sun.

Questions people ask

Can I cut back the leggy stems?
Yes, you can prune back long, bare stems in late winter. This encourages the plant to branch out and grow fuller.
Is my vine dying?
Probably not. Trumpet vines are very tough and usually just need better conditions to fill out again.
