Gardening classes in Palo Alto

Gardening in Palo Alto has its own rules. Most rain falls between November and April, summers are dry for months and clay soil is common. The good news is that fall is the best time to plant. It is also when local classes are busiest. A historic garden on Waverley Street teaches a steady run of workshops, the city gives away compost bins at free classes and the county's Master Gardeners offer science-based talks. A few places that used to teach gardening have closed, so this guide also notes what is gone.

We confirmed everything below on each organization's own site in early November 2026. Palo Alto options come first, then county and nearby programs, named as such. Schedules change each season.

Classes at a glance

Gamble Garden

Gamble Garden is a 2.5-acre historic garden and house at 1431 Waverley Street, open free every day during daylight hours. It is also the city's busiest garden classroom, with classes and workshops in horticulture, floral design and family programs. Its November 2026 calendar showed the range:

Gardener's Hour

The easiest way in is Gardener's Hour, a free gathering on the second Monday of every month. Gardeners of all ages meet to talk about their plots and swap plants, seeds and cuttings. Extras are given away to the community afterward. Gamble Garden asks you to register in advance.

Paid workshops

Hands-on workshops usually run 90 minutes to two hours. The garland class, for example, included all materials. Members get a 20% discount on most of them, sales are final and the garden issues refunds only if it cancels. The trees class was taught by Kevin Raftery, who has taught horticulture at Foothill College for many years. December brings the Winter Festival from December 3 to 5, with a holiday marketplace and tea. See the Gamble Garden events page for the full list.

Free compost workshops

The City of Palo Alto runs free composting workshops, sometimes with partners such as Gamble Garden. The draw for residents is a free compost bin or worm bin, one per household, for attending a workshop, while supplies last. The November 7 worm composting class covered how to turn kitchen scraps into a soil amendment for indoor and outdoor plants without smell or fuss. Registration is required online or by phone at (408) 918-4640. Our composting guide explains the green cart rules and how home compost fits in.

UC Master Gardeners of Santa Clara County

The UC Master Gardeners of Santa Clara County are trained volunteers with the University of California's Cooperative Extension. They give science-based talks on topics such as winter rose care, backyard chickens and pest control, run a help desk with an "Ask Us" option for gardening questions and staff plant sales. Talks move around the county. In January 2026, for example, the group held a rose care talk in Los Altos and an online class on backyard chickens. Their office is at 1553 Berger Drive in San Jose.

To go deeper, you can train as a Master Gardener yourself. The program trains a new class each January. Applications for the January 2027 class opened in summer 2026, so the next chance is likely summer 2027. Graduates are expected to volunteer after the course. Subscribe to the group's monthly Tips & Events newsletter to catch new talks near Palo Alto.

Palo Alto Adult School

The Palo Alto Adult School lists gardening in its home and environment classes. In fall 2026 it ran Gardening in Fall, a six-week Wednesday morning class on Zoom from September 9 to October 14, at $120, which covered fall planting and ways to winterize a garden. The same department offered an Ikebana class in the Sogetsu school and a short program with the Environmental Volunteers. Check the winter catalog for the next garden course.

Native plants and trees

For California natives, the Santa Clara Valley chapter of the California Native Plant Society runs a nursery at Hidden Villa in Los Altos Hills and holds plant sales each year. Canopy, the Palo Alto urban forestry nonprofit, offers free street trees and community planting days. Our native plants guide lists 2026 sale dates and nurseries. Our water-wise gardening guide covers rebates and watering rules.

What happened to Common Ground

Longtime gardeners still mention Common Ground, the organic garden supply store and education center at 559 College Avenue. It was a project of the nonprofit Ecology Action and taught biointensive gardening in Palo Alto from the 1970s. Ecology Action announced in 2014 that the store would close by the end of October that year. It said its research and demonstration garden on Arastradero Road would stay open for classes, but we could not find a current class schedule and the garden's old website now goes to a placeholder page. Ecology Action itself still teaches biointensive methods through online workshops and internships.

Tips for local gardeners

1. Plant in fall. October to early December is the best window. Winter rain settles new roots for free.
2. Know your soil. Many Palo Alto yards have heavy clay. Ask any class how to amend it before you plant.
3. Water early. City rules bar decorative watering with drinking water from 10 a.m. to 6 p.m.
4. Start with a swap. A free plant swap at Gardener's Hour fills a new bed cheaply.
5. Get a plot. If you have no yard, join the waitlist for a city community garden plot.
