Growing leafy greens in outdoor plant boxes is a fantastic way to enjoy fresh, homegrown produce with minimal space. Whether you're a beginner or an experienced gardener, certain plants thrive exceptionally well in containers. Here are some of the best leafy greens to consider:

1. Spinach – A nutrient-packed favorite, spinach grows quickly and can tolerate cooler temperatures, making it ideal for early spring or fall planting.

2. Kale – Hardy and versatile, kale is rich in vitamins and can withstand light frosts, extending your harvest season.

3. Lettuce (Butterhead & Romaine) – Fast-growing and available in many varieties, lettuce is perfect for successive planting to ensure a continuous supply.

4. Swiss Chard – With vibrant stems and tender leaves, chard is both ornamental and edible, thriving in partial shade or full sun.

5. Arugula – Peppery and quick to mature, arugula adds a zesty kick to salads and grows well in compact spaces.

For optimal growth, ensure your plant boxes have well-draining soil, receive at least 4-6 hours of sunlight daily, and are watered consistently. Rotate crops to prevent soil depletion and enjoy a bountiful harvest of fresh, leafy greens all season long!
