Meetings are held 9 times a year on the second Wednesday of the month and feature a lecture and slide presentation by a guest horticultural specialist. Each program also includes a member-led discussion and demonstration of unusual plants, as well as a plant sale of diverse plant varieties donated by members and local nurseries. All are welcome!


Current meeting location:   7:00pm on Zoom!     

If you enjoy the talks given at our meetings and want to help the Western Horticultural Society sustain our program, you might like to sponsor one of our speakers!

When is a Weed a Weed?

How to ID and Control Them

With Steve Fennimore, extension specialist & weed scientist, UC Davis

Weeds occur every day in our environment. Some species are natives and some are invasive. There are weeds that are highly poisonous like poison hemlock, and others that are delicious if properly prepared such as steamed burning nettle which

tastes like spinach.

We will discuss the characteristics of weeds that make them difficult to manage such as seed dormancy, dispersal and the perennial life cycle.

Additional topics will be weed identification, weed competition and the damage

that weeds inflict. We will discuss cultural, physical and chemical weed control methods, with a focus on how to control weeds using organic-compliant methods.

Steve Fennimore is an extension specialist and weed scientist with the University of California, Davis located at Salinas.

Since 1997, Steve has conducted a research and extension program focused on weed management in vegetables, flowers and strawberries in coastal production areas of California. His specialization is in non-chemical weed management for strawberry and vegetable crops.

Projects in his lab include automated weed removal and steam for soil disinfestation.

Steve grew up on a vegetable farm in western Oregon. From 1983 to 1993, he worked in the agricultural chemical industry holding research and development positions in California, Mississippi and Indiana with ICI Americas/Zeneca. Steve left industry and returned to graduate school at Purdue University where he received his PhD in weed science in 1997.
