Tips for Caring for Your Backyard Citrus Tree

As spring approaches, homeowners will notice their citrus trees are full of fresh fruit. Spring gardening season is also a good time to check your citrus trees for the Asian citrus psyllid, which can carry a deadly and incurable plant disease called Huanglongbing (HLB). HLB has already been found in urban areas of Los Angeles County, and it is a threat to California’s iconic citrus.

Follow these steps while tending to your citrus tree:

  • Inspect your tree for the Asian citrus psyllid. The pest is most noticeable when new leaves are growing on the tips of the branches.
    • Adult Asian citrus psyllids are small, brown pests that feed on citrus leaves with their body at a 45-degree angle.
    • Young Asian citrus psyllids, called nymphs, produce a white, waxy substance to direct honeydew away from their bodies.
  • If you think you have found the Asian citrus psyllid, report your findings to the California Department of Food and Agriculture at 800-491-1899.
  • Don’t move citrus fruit or plant materials off of your property, as this may help the Asian citrus psyllid spread.
  • Ask your local nursery about treatment options to help protect your trees from the Asian citrus psyllid.
