Companion planting is more than just a tradition; it's a form of intercropping. By placing tall, sun-loving plants (like Corn) next to shade-tolerant varieties (like Lettuce), you create a multi-story garden that produces more food per square foot.
The "Pest helpers" in our database use scent masking and trap cropping. Strongly scented plants like Basil or Marigolds confuse aphids, while others attract beneficial predators like hoverflies.
The "Avoid" column is crucial for preventing allelopathy—a biological phenomenon where one plant produces biochemicals that influence the growth of another. This chart helps you avoid stunted growth caused by poor pairings.
Many companions act as "Nitrogen fixers." Legumes like Peas and Beans pull nitrogen from the atmosphere and store it in the soil, acting as a natural fertilizer for "heavy feeders" like Broccoli and Cabbage.
