My Experience: Why This Hub Exists
I garden year-round in Sonoma Valley, starting thousands of seedlings each year for my raised beds, mounded beds, and containers. Over the decades I’ve learned how small adjustments—light height, seed depth, heat mats, watering method—make the difference between strong transplants and weak, leggy starts. This hub brings together that experience so you can start seeds with confidence and grow a more successful vegetable garden.
