Moonstone · Pachyphytum oviferum

Why is my Moonstone growing tall and stretched out?

A healthy Moonstone should be compact and tight, so if it starts growing tall with gaps between the leaves, it is reaching for more light. This is a classic sign of etiolation. Check your light levels first to ensure it is getting enough direct sun.

Check these first

  1. Observe how many hours of direct sun the plant gets.
  2. Check if the plant is leaning toward a light source.
  3. Compare the current growth to photos of healthy Moonstones.

Likely causes

  1. Insufficient Light

    Most likely

    How to tell: The stem is elongating and the leaves are spaced far apart. The plant leans heavily toward the nearest window.

    What to do: Move your plant to a spot that receives at least 6 hours of direct sunlight daily. If you do not have a sunny window, use a strong grow light positioned 6 to 10 inches above the plant.

  2. Seasonal Changes

    Possible

    How to tell: The plant stretches during the winter months when days are shorter. The growth is slower but still noticeably elongated.

    What to do: Reduce watering during the winter to slow down growth. Supplement with artificial lighting if the natural light is too weak.

When to worry

It is not a medical emergency, but the plant will not shrink back to its original shape. You may eventually need to behead the plant to restart its compact growth.

Stopping it coming back

Provide as much direct, bright light as possible throughout the year. Rotate your pot every week to ensure even growth on all sides.

Questions people ask

Can I fix the leggy stem?
You cannot shrink the existing stem. You can cut the top off, let it callus for a few days, and replant it to start a new, compact plant.
Is my plant dying because it is leggy?
No, it is just unhappy with its light situation. It is still alive, but it needs more sun to look its best.
