PresenterProgram:

The Latest on Polyphagous Shot Hole Borer (aka PSHB)

Guest Presenter:

Dr. John Kabashima

The March program focuses on a serious new insect pest threatening and affecting many species of landscape and forest trees in Southern California. The Polyphagous Shot Hole Borer (PSHB) is killing trees in Los Angeles, Orange, and parts of San Bernardino, Riverside, and San Diego counties. Though very tiny (< 1/10 inch), this wood-boring beetle is the vector for a fungus that causes Fusarium dieback, a disease that kills susceptible hosts. The beetle is known to feed on hundreds of different species, more than 110 of which are known to be susceptible to the disease. Scientists realized only two or three years ago that PSHB was a new exotic species and still don't know as much about the insect’s biology and control as they’d like. Recent observations, for example, show that the San Diego County infestation is a slightly different PSHB and is attacking commercial avocado trees in addition to landscape trees.

Coffee In The Garden: The Haynes Family Garden

Starting in 1977 with the removal of a boxwood hedge, the Haynes family garden has been an ever-changing project. It is used by fellow SCHS member and landscape designer/contractor Laramee Haynes as a display and test garden for Haynes Landscape Design. The garden has hosted various social events including 8 weddings, 14 open house/plant sales and countless Easter egg hunts. The new back patio garden includes many water-thrifty flowering plants and a slow-moving, heat-powered sculpture. The back garden nursery and greenhouse have produced thousands of plants that are well suited to our California climate and often hard to find. This working garden is ever changing with new puzzles to solve, care to give, joy to celebrate and sadness to endure. It is a story to tell for the many people who visit and care for it.

Please join us for an informal tour with coffee and light refreshments. This tour is free to SCHS members, but a $5.00 entry fee will apply to guests. Please sign up at the March meeting, online at the SCHS MemberLodge, by printing out and mailing in the PDF flyer, or by emailing

Deadline for registration is Friday, March 27.

About SCHS

Each month we invite speakers to present a talk or program about their area of expertise. SCHS Meetings are held on the second Thursday of each month, and usually include a digital or film slide presentation accompanied by handouts. Speakers are happy to answer questions from the audience. We also have an Plant Raffle at each meeting with plants provided by nurseries, botanic gardens or private collectors. Admission is free for members and children and $5 for non-members.

The Plant Forum table is fun! Members are encouraged to bring cuttings or plants from their gardens to display. Contributors receive a free raffle ticket. Later in the evening a local expert will lead a brief discussion about the plants. What an interesting way to learn!

SCHS Publications can be purchased at the monthly meetings. Plants, used and new books and magazines are also often for sale at the meetings.

The new SCHS Member Lodge is our interactive companion website where members can renew their membership, search the membership directory, and share information with fellow members.

Join us today and receive our SCHS Newsletter and Green Sheets (highlights from the monthly Plant Forum) plus the award-winning Pacific Horticulture, the magazine for West Coast gardeners (a $28 value). Many professional botanists, nurserymen & women, landscape architects & designers, students and consultants are also members. Our members grow an astounding array of plants in and around the LA Basin such as annuals, perennials, cacti and succulents, orchids, native plants and more. We also arrange members-only tours of private gardens and other garden related outings.

Intern Presentations

The 2011 presentations from Hallie Schmidt and David Latimer are now posted on our Intern Presentations page as PDFs. It is a pleasure to see how the SCHS can help young, energetic people learn valuable lessons in the world of horticulture.
