Tomato Harvest by Becca Ryan

Get ready for tomato season! The UC Marin Master Gardeners’ annual Tomato Market returns on Saturday, April 18 (9 a.m. until sold out) at Pini Ace Hardware in Novato and Bon Air in Greenbrae. Choose from a wide selection of tomato varieties grown from seed by local Master Gardeners and specially selected to thrive in Marin’s unique microclimates—whether you’re looking for heirlooms bursting with flavor or reliable favorites for your garden. Master Gardeners will be on hand to help you pick the perfect plants and share expert growing tips. Proceeds support Marin Master Gardener programs that bring gardening education to local schools and the community. Come early for the best selection!

A harvest of crisp, bright green lettuce is satisfying anytime of the year

Set Up Your Edible Garden for Success Before Planting. Learn how to prepare healthy soil, choose the right beds or containers, and use mulch and smart irrigation to help your vegetables and herbs thrive while conserving water.
