Why is my Indian hemp getting so leggy?

Leggy growth happens when Indian hemp is reaching out for more light than it is currently getting. Check your light levels to ensure your plant 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 window.
  3. Measure the distance between leaf nodes.

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 light source.

    What to do: Move the plant to a spot that receives full, direct sun for at least 6 to 8 hours a day. If indoors, place it directly in a south facing window.

  2. Lack of pruning

    Possible

    How to tell: The plant is tall and sparse but healthy otherwise. It has not been trimmed back in a long time.

    What to do: Prune the stems back by one third in early spring to encourage bushier, more compact growth. This helps the plant develop stronger stems.

When to worry

Leggy growth is not a disease, but it makes the plant structurally weak. It is a sign that the environment does not match the plant's needs.

Stopping it coming back

Keep the plant in a high light location and prune it annually to maintain a compact shape.

Questions people ask

You cannot make existing leggy stems shorter, but you can prune them to encourage new, fuller growth.
Does Indian hemp need full sun?
