Why are my Italian Cypress leaves turning yellow?

Yellowing foliage on an Italian Cypress often signals a struggle with pests or improper moisture. Check the underside of the needles for tiny webbing to rule out spider mites first.

Check these first

  1. Inspect the foliage for fine webbing.
  2. Check the soil moisture level with your finger.
  3. Look for tiny moving dots on the needles.

Likely causes

  1. Spider Mites

    Most likely

    How to tell: You will see fine webbing between the needles and the foliage will look dusty or bronze before turning yellow.

    What to do: Spray the tree thoroughly with a strong stream of water to dislodge the mites. If the infestation persists, apply neem oil or insecticidal soap every 7 days for 3 weeks.

  2. Overwatering

    Possible

    How to tell: The foliage turns yellow and feels soft or mushy rather than dry and brittle.

    What to do: Check the soil moisture 3 inches deep. If it is soggy, stop watering immediately and ensure the area has proper drainage.
