String of Buttons · Crassula perforata

Why is my String of Buttons growing so tall and thin?

A leggy plant is reaching out for more light. This happens when the plant does not get enough bright, indirect sun to stay compact.

Check these first

  1. Observe if the plant is leaning toward a light source.
  2. Compare the current light levels to the plant's needs.
  3. Rotate the pot every week to encourage even growth.

Likely causes

  1. Insufficient light

    Most likely

    How to tell: The space between the leaves gets larger, and the stems look stretched out. The plant leans heavily toward the nearest window.

    What to do: Move the plant to a brighter spot, such as a south or west facing window. If natural light is low, use a grow light for 8 to 10 hours a day.

  2. Seasonal changes

    Possible

    How to tell: The plant grows normally in summer but stretches during the dark winter months. This is a natural reaction to lower light levels.

    What to do: Reduce watering during the winter to slow growth. Move the plant to the brightest possible location in your home until spring returns.

Questions people ask

Should I prune the long stems?
Yes, you can trim the long stems to make the plant look fuller. You can even replant the cuttings in the same pot.
Will the stems fill back in?
Unfortunately, the stretched parts will not shrink back. Pruning is the best way to restore a compact shape.
