• Irrigation Management: Drip irrigation can help meet the different watering needs.

• Proper Spacing: Allow enough space for watermelon vines to spread without encroaching on cabbage.

Planting Tips & Best Practices

• Optimal Spacing: Plant cabbage 18-24 inches apart, watermelons 36-60 inches apart, and nasturtiums 10-12 inches apart.

• Timing: Plant cabbage in early spring or fall, watermelons after the last frost, and nasturtiums in late spring.

• Container vs. Garden Bed: Use garden beds for better space management. Containers can work for nasturtiums.

• Soil Preparation: Amend soil with compost for cabbage and watermelons; nasturtiums prefer less fertile soil.

• Additional Companions: Consider adding marigolds, which also deter pests and can be compatible with all three plants.
