Heath Milkwort · Polygala serpyllifolia

Why is my Heath Milkwort looking leggy?

Leggy growth means your plant is stretching out to find more light. Check where your plant is sitting to see if it is getting enough bright, indirect light.

Check these first

  1. Observe the light levels in the current location.
  2. Rotate the pot to ensure even light exposure.
  3. Check if the plant is crowded by other objects.

Likely causes

  1. Insufficient Light

    Most likely

    How to tell: The stems are long and thin with large gaps between the leaves. The plant is leaning heavily toward the nearest window.

    What to do: Move your plant to a spot with brighter, indirect light. If you cannot provide enough natural light, consider using a grow light for 8 to 10 hours a day.

  2. Lack of Pruning

    Most likely

    How to tell: The plant has grown tall and sparse over time without any intervention. The foliage is concentrated only at the very tips of the stems.

    What to do: Prune back the long, leggy stems to encourage bushier growth. Use clean, sharp shears to cut just above a leaf node.

When to worry

Legginess is rarely fatal but it does affect the plant's appearance. It is normal for the plant to stretch slightly during the darker winter months.

Stopping it coming back

Provide consistent bright, indirect light and prune your plant regularly to maintain a compact shape.
