Wand loosestrife · Lythrum lineare

Why are my Lythrum lineare leaves turning yellow?

Yellowing leaves are less common for this plant, as it is quite hardy in the right spot. This usually happens when the soil dries out too much or the plant is not getting enough sun.

Check these first

  1. Touch the soil to see if it feels dry to the touch.
  2. Check if the plant is receiving at least 6 hours of direct sunlight.

Likely causes

  1. Drying out

    Most likely

    How to tell: The lower leaves turn yellow and crispy because the soil has lost its moisture.

    What to do: Water your plant immediately until the soil is saturated. Keep the soil consistently damp by checking it every day, especially during hot weather.

  2. Insufficient light

    Possible

    How to tell: The leaves turn a pale yellow and the stems look weak or stretched.

    What to do: Move your plant to a location that receives full, direct sun for at least 6 to 8 hours a day. If you are growing it indoors, place it in the brightest south facing window you have.
