The Ultimate Seed Starting Guide: Everything You Need to Know For Starting Seeds Indoors: Best of Growing Joy Replay

If you’re new to gardening, seed starting indoors can feel scary and overwhelming. I know it did for me. For a long time, I stuck to buying seedlings because starting seeds felt like too much. The equipment, the space, the timing, the fear of doing it wrong. All of it can feel intimidating, especially for new plant parents.

In today’s episode, we’re bringing back a favorite from the Growing Joy archives all about starting seeds indoors for beginners, featuring the ultimate seed-starting expert, Joe Lamp’l of joegardener.com. Joe is a longtime garden mentor and friend of mine, and in this conversation, he completely demystifies seed starting basics. We break down the why behind the how, making seed starting feel approachable, doable, and genuinely fun.

Some of the most flavorful tomatoes I’ve ever grown came from seed. When you grow vegetables from seed, you’re not limited to what’s available at the garden center. You get access to incredible varieties you’ll never find as seedlings, and that’s one of the most rewarding parts of gardening.
