How to Grow Spinach Indoors All Year Round

Spinach is packed with nutrients and super easy to grow indoors. It’s a cool-weather crop that doesn’t mind lower indoor temperatures, making it perfect for growing year-round. Plus, you can harvest baby leaves quickly for salads or smoothies.

Use a wide container that’s at least 6 inches deep, fill it with a rich, moist potting mix, and sow seeds about half an inch deep. Keep it in a sunny window or under grow lights for at least 6 hours a day. Water regularly but avoid overwatering.

You can start harvesting spinach leaves in as little as 3–4 weeks. Snip the outer leaves first and let the inner ones keep growing. The more you harvest, the more it grows—so keep those salads coming!
