Why Start from Seed?
Starting plants from seed is one of the most rewarding skills a gardener can learn. It costs a fraction of buying transplants, gives you access to hundreds of heirloom varieties you'll never find at the nursery, and lets you control every stage of your plant's early life. Plus, there's something magical about watching a tiny seed push through the soil and become food on your table.
Timing Is Everything
The biggest mistake beginners make is starting too early—or too late. Most seed packets list "days to maturity" and suggest when to start indoors relative to your last frost date. Count backward from your expected last spring frost, and you'll have strong, ready-to-transplant seedlings exactly when the weather cooperates. A simple frost date search for your zip code is all you need to get this right.
Light and Temperature
Seeds don't need light to germinate, but they need it the moment they emerge. Place seed trays in the sunniest window you have—south-facing is ideal in the Northern Hemisphere—or under grow lights for 14-16 hours daily. Most vegetable seeds germinate best between 65-75°F, so a heat mat under your trays can dramatically improve germination rates and speed.
Watering and Airflow
Consistent moisture is critical, but overwatering is the silent killer of seedlings. Water from below by setting trays in a shallow pan of water and letting soil soak it up. This encourages deep root growth and keeps foliage dry. Once seedlings have their first true leaves, introduce gentle airflow with a small fan to strengthen stems and prevent damping-off disease.
Hardening Off Before Transplanting
Indoor seedlings are coddled—they've never experienced wind, direct sun, or temperature swings. About two weeks before planting outside, start exposing them gradually: an hour of indirect light the first day, two hours the next, slowly building to full sun and overnight stays outdoors. Rushing this step shocks plants and sets back growth significantly.
Getting Started
Seed starting requires just a few supplies: sterile seed-starting mix, small containers or trays, labels (you will forget what's what), and patience. Everything else is refinement.
