Joseph's coat · Alternanthera dentata

Why is my Joseph's coat dropping leaves?

It is less common for this plant to drop leaves, but it usually happens when the plant is stressed by sudden changes in its environment. Check the soil moisture levels first to see if you have been overwatering or underwatering.

Check these first

  1. Check the top inch of soil for dryness.
  2. Inspect the plant for signs of pests.
  3. Evaluate if the plant was recently moved to a new location.

Likely causes

  1. Inconsistent watering

    Possible

    How to tell: The soil feels bone dry or soggy, and the leaves look wilted before they fall off.

    What to do: Water when the top inch of soil feels dry to the touch. Aim for a consistent schedule every 3 to 7 days depending on your home temperature.

  2. Low light

    Possible

    How to tell: The plant looks stretched out and the lower leaves turn yellow before dropping.

    What to do: Move your plant to a spot with bright indirect light or partial sun. Ensure it gets at least 6 hours of light daily to keep it full.
