In this video I’m walking you through spinach facts and planting strategies that get you earlier harvests—without starting anything indoors. Here in Maryland Zone 7, spinach is one of the best overwintering crops I grow. I show you beds of spinach on March 11th that are already close to harvest, and then I hit the key idea: those plants have been in the ground about 4 1/2 months because I planted them October 23rd, about 6–8 weeks before the soil regularly drops below 40°F. Once soil temps are under 40°F, plants basically stop growing (they can survive, but they don’t grow), so the goal is to get germination and small, established plants before the real cold locks things up. Small spinach plants are extremely hardy—often handling 10–20°F, and even brief dips near 0°F—while bigger plants may get outer leaves beat up (the crowns still come back strong). I also explain why spinach tolerates freezing: as temps drop it converts starches into sugars that act like antifreeze in the plant cells. To wake overwintered spinach, I like a simple approach: water-soluble fertilizer to green it up, and I’ll often drop in more seed right then—about 1/4 inch deep, usually two seeds per hole—so I’ve got spinach coming in stages all spring.
