Common hedgenettle · Betonica officinalis

Why is my hedgenettle growing so tall and thin?

A leggy hedgenettle is usually stretching out because it is not getting enough light. Check where your plant is sitting to see if it needs a brighter spot.

Check these first

  1. Observe how much light the plant receives throughout the day.
  2. Rotate the pot to ensure all sides get equal light exposure.
  3. Check if the stems are reaching toward a light source.

Likely causes

  1. Insufficient Light

    Most likely

    How to tell: The stems are long and weak with large gaps between the leaves. The plant leans heavily toward the nearest window.

    What to do: Move your plant to a spot with bright, indirect light or some direct sun. If you cannot provide more natural light, consider using a grow light for 8 to 10 hours a day.

  2. Lack of Pruning

    Most likely

    How to tell: The plant is tall but has not been trimmed, leading to sparse growth at the base. It looks top heavy and thin.

    What to do: Prune back the stems by one third to encourage bushier growth. Regular trimming helps the plant stay compact and full.

When to worry

Legginess is not a disease, but it makes the plant look untidy. It is normal for the plant to stretch slightly if the seasons change and light levels drop.

Stopping it coming back

Keep your plant in a bright location and prune it back occasionally to maintain a compact shape. Rotate the pot every week so it grows evenly.

Questions people ask

Will my plant fill out again after I prune it?
Yes, pruning stimulates new growth from the nodes. It will look much fuller after a few weeks of good light.
Is full sun too much for my hedgenettle?
No, this plant enjoys full sun to partial shade. Just make sure it is acclimated slowly if you move it from a dark room to a sunny porch.
