Why Grow Spinach?

Spinach isn't just another leafy green – it's a nutritional superhero packed with iron, vitamins, and antioxidants. This versatile crop offers gardeners an incredibly rewarding growing experience, whether you're a beginner or seasoned cultivator.

Strategic Planting Timeline

Timing is everything with spinach. Unlike heat-loving crops, spinach thrives in cooler temperatures and offers multiple planting windows:

Early Spring Planting

• 4-6 weeks before last frost
• Soil temperature: 40-75°F
• Ideal for quick spring harvest

Fall Planting

• 6-8 weeks before first expected frost
• Produces sweeter, more tender leaves
• Less pest pressure

Pro Tip: Use succession planting (every 2 weeks) to ensure continuous harvest throughout the growing season.
