Reap What You Sow: Starting Cool-Season Seeds Indoors for Fall
- Get the Goodies. For fall crops, pick the hardiest and most frost tolerant seeds, so they can survive the first frost. Some of our favorites include broccoli, cabbage, kale, cauliflower, beets, carrots and spinach.
- Time to Prime. Start from the fall frost date (around here, the end of September) Look at the number of days to harvest on each seed packet. Use that number to count back from the first frost date, so the seeds have time to mature. Play it safe and add two weeks since plants can grow slower during short fall days.
- Awaken the Seeds. Fill seed starting trays within ¼” of the top with a high-quality organic seed starter, like Espoma’s Organic Seed Starter. Read each seed packet to learn how deep and far apart to plant seeds. Cover with soil, press down, label and lightly water.
- Store and Cover. Lightly cover the tray with plastic wrap. Keep in a sunny spot near a south-facing window.
- Smart Watering. Keep seeds moist by placing the tray in a pan of shallow water until the water seeps up from the bottom. Refill when empty.
- Break Out Sprouts. When leaves start to poke from the soil, remove plastic wrap. Feed with an organic fertilizer, like Espoma’s Plant-tone.
- A Home Away from Home. Two weeks before planting outside, begin hardening off seeds. Move outside for a few hours a day, increasing time outdoors daily. Also, reduce watering without letting the soil dry out.
- All Grown Up! Gently remove plants from see starting tray, and plant in a prepared bed. Mix-in organic starter plant food to help them adjust and grow strong, such as Espoma’s Bio-tone Starter Plus.
