Milkweed · Asclepias

Why is my milkweed losing its leaves?

This is less common for milkweed, but it usually happens when the plant is experiencing extreme environmental stress. Check the soil moisture first to see if the plant is either too dry or sitting in soggy soil.

Check these first

  1. Check if the soil is too wet or too dry.
  2. Assess how many hours of direct sun the plant receives.
  3. Look for aphids or other pests on the stems.

Likely causes

  1. Extreme moisture stress

    Possible

    How to tell: Leaves turn yellow or brown before falling off, often starting from the bottom of the stem.

    What to do: Adjust your watering to the 7 to 14 day cycle. Ensure the soil is moist but never swampy.

  2. Lack of light

    Possible

    How to tell: The plant becomes leggy and drops leaves because it cannot support them without enough sun.

    What to do: Move the plant to a location that receives full, direct sun for at least 6 to 8 hours a day. Prune back leggy stems to encourage bushier growth.

When to worry

Worry if the plant is losing a large number of leaves all at once. It is normal for a plant to lose a few leaves when adjusting to a new spot.

Stopping it coming back

Keep the plant in a bright, sunny spot and stick to a steady watering routine.
