Questions about plant problems

UC has created an extensive Home, garden, turf, and landscape pests website with information on all sorts of problems California gardeners are likely to encounter. Search by the plant name to see a list of all of the pests it is subject to, or search by pest name if known or symptoms.

We also have a Hotline you can contact by phone or email or visit in person. Please use our Plant Diagnostics page to gather pertinent information before calling.

Information about specific plants
