Why is my Motherwort growing tall and leggy?

Motherwort becomes leggy when it is stretching to find more light. Check the spot where your plant lives to see if it is getting enough bright, indirect light throughout the day.

Check these first

  1. Observe if the plant is leaning toward a light source.
  2. Measure the distance between leaf nodes to see if they are stretched out.
  3. Check if the plant has been pruned recently.

Likely causes

  1. Insufficient Light

    Most likely

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

    What to do: Move your plant to a brighter location that receives full sun or bright indirect light. Rotate the pot every week so all sides get even exposure.

  2. Lack of Pruning

    Most likely

    How to tell: The plant is tall and sparse but otherwise healthy. It has not been trimmed back during the growing season.

    What to do: Prune the top stems back by a few inches to encourage bushier growth. Regular pinching of the tips helps the plant fill out rather than growing straight up.

When to worry

Legginess is rarely fatal but it makes the plant look weak. It is normal for the plant to grow tall as it matures, but it should still look sturdy.

Stopping it coming back

Provide plenty of light and prune the tips regularly to keep the plant compact and full.

Questions people ask

Will my leggy stems fill back in?
The existing stems will not grow new leaves in the bare spots. Pruning them will encourage new, fuller growth from the base.
How much light does Motherwort need?
It thrives in full sun to partial shade. If you are growing it indoors, a bright window is best.
