Advice to Grow By...Ask Us!

UC Master Gardener advice and problem diagnosis services are available year-round!  For problem diagnosis and answers to your gardening questions, contact our Help Desk.  The Help Desk is open 50 weeks of the year, Monday through Thursday, from 9:00 am to Noon (closed winter holidays). Due to the current COVID-19 restrictions, our Master Gardeners are working remotely—

In your request—

  • Include your name, phone number and city (plant advice depends on local conditions!).
  • Describe the problem in detail. Include the name of the plant if known, when the problem began, and cultivation history such as watering, fertilizing, pruning, pesticides, etc. 
  • Send photographs, if applicable. Photographs help!

Our gardening blog, HOrT COCO, talks about seasonal hot topics, frequently-asked questions, and truly unique or peculiar requests for help. Subscribe here.
