Why are my Blanket Flower leaves turning yellow?

Yellowing leaves on your Blanket Flower usually signal that the roots are struggling with too much moisture. Check your soil drainage first to see if the plant is sitting in water.

Check these first

  1. Feel the top inch of soil for moisture.
  2. Inspect the base of the stem for mushy tissue.
  3. Check drainage holes for any blockages.

Likely causes

  1. Overwatering

    Most likely

    How to tell: The lower leaves turn yellow and feel soft or mushy to the touch.

    What to do: Stop watering immediately and let the top 2 inches of soil dry out completely. Ensure your pot has drainage holes or that your garden bed is not in a low spot where water pools.

  2. Poor Drainage

    Possible

    How to tell: The soil remains soggy for days after watering and the plant looks generally weak.

    What to do: Amend heavy clay soil with compost or perlite to improve aeration. If the plant is in a container, repot it into a well draining potting mix.

When to worry

If the yellowing spreads rapidly to the entire plant, it is likely suffering from root rot and may not recover. A few yellow leaves at the very base are normal as the plant grows.

Stopping it coming back

Only water when the top inch of soil is dry and always plant in full sun with excellent drainage.
