Daisy fleabane · Erigeron strigosus

Why are my Daisy fleabane leaves turning yellow?

Yellowing leaves are less common for this hardy native plant, but they usually signal issues with soil moisture or drainage. Check the soil around the base of your plant first to see if it is sitting in soggy ground.

Check these first

  1. Feel the soil moisture at a depth of 2 inches.
  2. Inspect the base of the plant for standing water.
  3. Check the leaves for signs of pests that might drain sap.

Likely causes

  1. Overwatering

    Most likely

    How to tell: The lower leaves turn yellow and feel soft or mushy to the touch. The soil stays wet for more than a few days after watering.

    What to do: Stop watering immediately and let the top 2 inches of soil dry out completely. Ensure your planting site has excellent drainage, or consider moving the plant to a spot with looser soil.

  2. Nutrient Deficiency

    Possible

    How to tell: The leaves turn a pale yellow color while the veins remain green. This often happens if the plant has been in the same spot for a long time without fresh compost.

    What to do: Apply a balanced, slow release fertilizer in early spring. You can also top dress the soil with an inch of organic compost to provide steady nutrients.

When to worry

Worry if the yellowing spreads rapidly across the whole plant. It is normal for the very oldest leaves at the bottom to yellow and drop as the plant grows.

Stopping it coming back

Maintain a consistent watering schedule of every 3 to 7 days, and always ensure the soil drains well.
