Succession planting in outdoor plant boxes is a smart gardening technique to ensure continuous harvests throughout the growing season. By carefully selecting plants that thrive in different stages, you can maximize space and yield. Here are some of the best plants for succession planting:

1. Leafy Greens (Spring/Fall): Spinach, lettuce, and kale grow quickly and can be replanted after harvest.

2. Root Vegetables (Early Summer): Radishes and carrots are ideal for early planting, followed by faster-growing crops.

3. Beans and Peas (Summer): These nitrogen-fixing plants enrich the soil for subsequent plantings.

4. Fast-Growing Herbs (Year-Round): Basil, cilantro, and dill can be interplanted for continuous harvests.

5. Cool-Season Crops (Late Fall/Winter): Broccoli and Brussels sprouts thrive in cooler temperatures.

Rotate these plants based on their growth cycles to keep your outdoor plant boxes productive all year. Pairing complementary plants also improves soil health and reduces pests. Happy gardening!
