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.

Seed-Starting Essentials
Find the supplies you need to give seeds a strong start. Product selection may vary by location.
Seed-Starting Mix
A lightweight seed-starting mix provides the moisture retention and drainage young seedlings need. Unlike ordinary garden soil, it is formulated for use in trays, cells and small pots.
E.B. Stone Organics Seed Starter Potting Soil is a lightweight mix formulated for starting seeds and rooting cuttings.
Trays, Cells and Pots
Keep seedlings organized with seed trays, cell inserts, biodegradable pots and covered greenhouse kits.
Available options may include:

- AccelaRoot propagation plugs and cell inserts
- Float grow trays
- Covered greenhouse kits
- Jiffy-Strips biodegradable seed-starting cells
- Jiffy-Pots
Grow Lights
Strong light helps seedlings develop compact growth and sturdy stems. Grow lights are especially helpful when natural indoor light is limited.
Watering and Planting Tools
A mister or watering can with a gentle stream helps moisten seeds without washing them out of place. Plant labels, garden gloves and a hand trowel make sowing and transplanting easier.
Seedling Heat Mats
Heat mats can improve germination for warmth-loving seeds. Because many cool-season vegetables and flowers prefer lower germination temperatures, always follow the temperature guidance on the individual seed packet.
