Plant Sale
Our Fall Garden Fair plant sale offers a bounty of winter vegetable, herb, ornamental, and native plant seedlings plus beautiful low-water succulents and garlic/shallot bulbs. They all thrive in our cool winter conditions and will keep your garden producing year-round. Come get inspired!
Arrive early for best selection. Some varieties may sell out quickly or be in short supply. Please bring a box, cart, or wagon for an easier shopping experience. Only service dogs permitted in the sales area. We suggest wearing sturdy shoes for walking on the uneven wood chip mulched sales area.
Plants start at $5. Cash, checks, and credit/debit cards are all accepted. Proceeds support the Master Gardeners' mission.
Gardening Talks
Join us for talks by UC Master Gardeners. No registration needed. See talk schedule.
Seed Exchange
Come join in the age old tradition of sharing seeds. Sharing community seeds builds resilience in our food systems and genetic diversity in our seeds. Bring saved seed or leftover seed packets to share. Label your seeds with common name, year of harvest, and your zip code. You’re welcome to take seeds even if you don’t have any to share this year.
Information Tables
- Help Desk: Bring your questions and plant or pest samples to our Help Desk booth for assistance with your garden problems.
- Tool Care: See live demonstrations of how to keep your tools sharp and in tip-top condition. Bring your own hand pruner (it must be in working condition) and learn to sharpen it yourself.
- Master Composters: Learn about composting and composting resources in Santa Clara County
- Master Food Preservers: Find out how to preserve your garden bounty with safe, effective techniques.
Visit our many garden collections: native plants, succulents, orchard, and more. Check out our One World Kitchen Garden for new ideas and interesting plants from around the world. There will be a Cover Crop Demonstration area in the raised beds between the Pavilion and the Farm Stand, where you can get your cover crop questions answered.
Fall Vegetables, Herbs, Flowers, Native Plants, and Succulents Questions: The Master Gardeners in any of our sales areas will be happy to answer your questions on growing, harvesting, dealing with problems, special varieties, and more.
Children's Activities
Kids will have a great time in our Growing Young Gardeners area. Come see what fun our volunteers have in store. Learn about gardening and how food grows with a variety of fun activities. For kids of all ages.
