Why are there spots on my garden strawberry leaves?

Spots on strawberry leaves are almost always caused by fungal issues that thrive in humid or crowded conditions. Improving air circulation is the first step to stopping the spread.

Check these first

  1. Check if the leaves are crowded and touching.
  2. Examine the spots to see if they are fuzzy or dusty.
  3. Ensure the plant is in a spot with good sunlight.

Likely causes

  1. Powdery Mildew

    Most likely

    How to tell: A white, dusty coating appears on the leaves, which may eventually cause them to curl or turn brown. It happens when air circulation is poor.

    What to do: Prune away infected leaves to improve airflow. Spray the foliage with a mixture of one part milk to nine parts water or a fungicide.

  2. Leaf Spot Disease

    Possible

    How to tell: Small purple or reddish spots appear on the leaves, often with a white or gray center. These spots can grow and merge over time.

    What to do: Remove and dispose of all infected leaves immediately. Avoid overhead watering to keep the foliage dry.

When to worry

Minor spotting is common in late summer. Worry if the spots cover most of the leaf surface or start appearing on the fruit.

Stopping it coming back

Water at the base of the plant to keep leaves dry and provide plenty of space between plants.
