What to Plant in a 2×4 Raised Bed?

When selecting crops, consider their growth habits, sunlight needs, and space requirements. Here are the best options:

1. Root Vegetables

• Carrots – Need loose, well-draining soil to develop properly. Avoid compacted garden soil.

4. Legumes

• Peas & Beans – Nitrogen-fixing plants that improve soil fertility. Support climbing varieties with a trellis.

5. Cucurbits

• Melons – Select smaller varieties like Sugar Baby watermelons and train them onto a trellis.
• Herbs – Mint, basil, oregano, and thyme grow well and require minimal space.

Companion Planting for Maximum Yield

Pairing compatible plants can improve growth, repel pests, and enhance flavor. Consider these companion planting suggestions:
