How Companion Planting Works
Pest Deterrence
Some plants repel pests that attack their neighbors. Basil near tomatoes repels aphids and whiteflies.
Nutrient Sharing
Legumes (beans, peas) fix nitrogen in the soil, benefiting nearby heavy feeders like corn and squash.
Space Optimization
Tall plants shade heat-sensitive crops. Deep-rooted plants break up soil for shallow-rooted neighbors.
