💡 High-Yield Groupings

• The Three Sisters: Plant corn, beans, and squash together. Corn provides support, beans fix nitrogen, and squash leaves shade weeds.
• The Salad Bowl: Group lettuce, chives, and carrots. They share space efficiently and chives keep pests off the greens.
• The Pest Blocker: Plant marigolds and basil alongside tomatoes to naturally repel hornworms and nematodes. [1, 2, 3, 4, 5]
