We need your help to prevent the spread of citrus diseases. You have heard the saying “move it or lose it.” Well, when it comes to citrus trees, we say “Move It AND Lose It.” When you move citrus trees, you risk losing America’s citrus altogether.

5 Things You Need to Know

  1. Be Aware of Quarantines. After Asian citrus psyllid discoveries in southern California, quarantines have been established in Imperial, Los Angeles, Orange, Riverside, San Bernardino, San Diego, Santa Barbara and Ventura counties. Do not move citrus trees, fruit or trimmings from this area. Not only are you risking spreading citrus diseases, but it's also against the law.
  2. Inspect Citrus Plants Regularly for Diseases and Insects. Check citrus plants for signs of citrus diseases. If you detect an infected plant, report it immediately.
  3. Keep Homegrown Citrus at Home. Help reduce the spread of citrus diseases by not moving your homegrown citrus fruit or plants from quarantine areas.
  4. Check the Citrus Plant Supplier. Be a savvy buyer. Buy citrus plants only from a reputable, licensed California nursery.
  5. Avoid Fines and Penalties. If you knowingly purchase citrus in violation of quarantine regulations and requirements, the penalties could range from $1,100 to $60,000 per violation.
