These versatile veggies not only add vibrancy to your garden but also pack a nutritional punch. In this comprehensive guide, we’ll explore eight leafy green vegetables that you can plant in some parts of the U.S. in October. From planting tips to nutritional benefits, we’ve got you covered.

1. Spinach (Spinacia oleracea)

Spinach is a classic leafy green, beloved for its tender leaves and versatility in the kitchen. It prefers well-draining soil enriched with organic matter best suited for USDA zones 3 to 9. This cool-weather crop thrives in temperatures between 35°F to 75°F (1.5°C to 24°C). When planting in October, you can expect spinach to mature within 40 to 50 days.

Spinach is a nutritional powerhouse, rich in vitamins A and K, iron, and folate, making it an excellent addition to your fall garden and your diet.

2. Kale (Brassica oleracea var. sabellica)

Kale, with its robust and curly leaves, is not only visually appealing but also nutritious. It can thrive in USDA zones 7 to 10. This cold-hardy green can tolerate frost, and it prefers well-draining soil. In zones 7 and above, providing partial shade can help prevent bolting. October planting ensures a steady supply of fresh kale well into the cooler months. Kale typically matures within 55 to 75 days, depending on the variety. Harvest the outer leaves first, allowing the inner leaves to continue growing. Kale is a nutritional powerhouse, rich in vitamins A, C, and K, as well as calcium and fiber.
