Plant Clinic Online

Have a sick plant, an ailing tree, mysterious spots on leaves? Chat with a UC Master Gardener via Zoom to diagnose your plant problems. You can also listen and learn while other people ask their questions. The Plant Clinic Online takes place on the second Tuesday of the month, March–October, from 7–8:30 pm. Priority will be given to questions that are emailed in advance; instructions are in the Zoom registration confirmation.

2025 dates: March 11, April 8, May 13, June 10, July 8, August 12, September 9, October 14

No plant clinic November–February

The circles cut out of the leaf pictured above were done by leafcutting bees. They use the leaf material to line their nests. There's nothing wrong with the plant!
