Seeds to Start in August

Late summer is an important seed-starting season in the Bay Area. Cool-season vegetables, herbs and flowers can get established while the soil is still warm, then grow and mature as temperatures begin to fall.

In warmer inland locations, protect newly sown seeds from intense afternoon sun and postpone outdoor sowing during a heat wave. Keep seed-starting mix or garden soil consistently moist while seeds germinate.

All of the seeds featured below are available through our selection of Botanical Interests Seeds. All Botanical Interests seeds are untreated and Non-GMO Project Verified. As you browse our in-store selection, look for heirloom and certified organic varieties.

Please Note: Selection of seeds may vary by location.
