Coral Bells · Heuchera

Why is my Heuchera looking leggy?

It is less common for Heuchera to become leggy, as they typically grow in a neat, compact mound. This is usually caused by a lack of sufficient light or the plant needing to be divided.

Check these first

  1. Observe the light levels in the current spot.
  2. Check if the plant has become a large, woody clump.
  3. Look for signs of stretching toward a light source.

Likely causes

  1. Low Light

    Possible

    How to tell: The stems stretch out and the leaves become sparse as the plant reaches for more light. The foliage may also lose its intense color.

    What to do: Relocate the plant to a brighter location with partial shade. If it is in full shade, move it where it gets morning sun.

  2. Overcrowding

    Possible

    How to tell: The plant has grown very large and the center is becoming woody or sparse. This happens when the plant has not been divided for several years.

    What to do: Dig up the plant in early spring or fall and divide it into smaller sections. Replant the healthy, vigorous outer pieces and discard the woody center.

When to worry

It is normal for older Heuchera to develop a woody stem over many years. If the plant is young and stretching, it is a sign that it needs more light.

Stopping it coming back

Divide your Heuchera every 3 to 4 years to keep the plant vigorous and compact.
