Plantain Lily · Hosta

Why are my Hosta leaves turning yellow?

Yellowing leaves on a Hosta usually point to a moisture issue or too much sun exposure. Check your soil moisture levels first to see if the plant is getting too much or too little water.

Check these first

  1. Feel the soil two inches deep.
  2. Observe how much direct sun the plant gets.
  3. Check for signs of standing water near the base.

Likely causes

  1. Overwatering

    Most likely

    How to tell: The leaves feel soft and mushy, and the soil stays wet for days.

    What to do: Stop watering until the top inch of soil feels dry. Ensure your garden bed has good drainage by adding organic matter like compost.

  2. Sun Scorch

    Possible

    How to tell: Leaves in the brightest part of the garden turn yellow or bleached.

    What to do: Move the plant to a shadier spot or install a shade cloth. Hostas prefer partial to full shade to keep their foliage healthy.

When to worry

It is normal for older leaves at the base to yellow and die back in late summer. Worry if the yellowing spreads rapidly across the whole plant.

Stopping it coming back

Maintain consistent soil moisture and ensure the plant is placed in a spot with appropriate shade.
