Why are my Heath Milkwort leaves turning yellow?

Yellowing leaves usually signal that your plant is unhappy with its moisture levels or light exposure. Check the soil moisture level first to see if you are overwatering.

Check these first

  1. Feel the soil to see if it is waterlogged.
  2. Observe the plant's position relative to light sources.
  3. Look for pests on the undersides of the yellow leaves.

Likely causes

  1. Overwatering

    Most likely

    How to tell: The lower leaves turn yellow and feel soft or limp. The soil feels consistently wet to the touch.

    What to do: Reduce your watering frequency and ensure the pot drains well. Allow the soil to dry slightly more between waterings.

  2. Low Light

    Possible

    How to tell: The leaves turn pale yellow and the plant starts to stretch out. This happens when the plant is kept in a dark corner for too long.

    What to do: Move your plant to a spot with bright, indirect light. A location near a window that gets partial sun is ideal.
