Why is my geranium growing so leggy?

A leggy geranium is reaching out because it is not getting enough light. This causes the stems to stretch thin and weak as they search for the sun.

Check these first

  1. Measure how many hours of direct sun the plant gets.
  2. Check if the plant is leaning toward a light source.
  3. Look for crowded conditions that block light.

Likely causes

  1. Insufficient light

    Most likely

    How to tell: The stems are long and thin with large gaps between the leaves.

    What to do: Move your plant to a spot that receives at least 6 hours of direct sunlight daily. If you are growing indoors, place it in a south facing window.

  2. Lack of pruning

    Possible

    How to tell: The plant is tall and sparse even though it gets decent light.

    What to do: Pinch back the growing tips of the stems regularly to encourage bushier, lateral growth. Do this throughout the spring and summer.

When to worry

Legginess is rarely fatal but makes the plant look sparse and prone to tipping over. It is a sign the plant needs a change in environment.

Stopping it coming back

Prune your geraniums back in early spring and ensure they have a bright, sunny home.
