The 8 Best Leafy Green Vegetables You Can Still Plant in October

4. Lettuce (Lactuca sativa)

Next up, lettuce. It comes in various types, including butterhead, romaine, and leaf lettuce, each with its unique flavor and texture. It’s well-suited for USDA zones 3 to 10. Lettuce prefers cooler temperatures (optimum growing temperatures of 60 to 65°F, or 15 to 18°C) and well-draining soil. In warmer zones, providing partial shade can help prevent bolting. Planting lettuce in October ensures a steady supply of fresh, crisp leaves for salads and sandwiches. Lettuce typically matures within 30 to 60 days, depending on the variety. Harvest leaves when they reach the desired size, typically 4 to 6 inches (10 to 15 cm). Lettuce is low in calories and a good source of vitamins A and K.

5. Arugula (Eruca vesicaria subsp. sativa)

Arugula’s peppery, nutty flavor adds a zesty kick to salads and other dishes. It thrives in USDA zones 3 to 11 and prefers well-draining, slightly acidic soil. Arugula can tolerate partial shade in warmer regions. Planting arugula in October allows you to enjoy its rapid growth and fresh, crisp leaves. Furthermore, arugula typically matures within 30 to 40 days, and you can start harvesting when the leaves are 2 to 3 inches (5 to 8 cm) long. Arugula is high in vitamins C and K, as well as folate and calcium — talk about a nutritious and flavorful addition to your garden and your meals!

6. Mustard Greens (Brassica juncea)

Next, mustard greens have a spicy and slightly bitter flavor, making them a favorite in Southern cuisine. They thrive in USDA zones 6 to 11 and prefer well-draining, fertile soil. Mustard greens can tolerate partial shade in warmer zones. What’s more, planting them in October ensures you’ll have flavorful greens as they reach their peak tenderness. Mustard greens typically mature within 40 to 50 days. Harvest the leaves when they are young and tender, usually at around 4 to 8 inches (10 to 20 cm). Mustard greens are a good source of vitamins A, C, and K, as well as calcium and iron.
