Minimize Risk

Complementary seedlings increase the chances of obtaining higher yields even if a crop fails or is affected by natural difficulties such as weather, pests, or disease.

Positive Housing

Planting near plants that produce excess nectar and pollen can increase the population of beneficial insects that control harmful pests. When it comes to soil chemistry (an example would be brassicas and potatoes), the acidic soil in which potatoes thrive can cause problems for some brassicas. For example, moist, acidic soil can accommodate club roots, which can be a real problem for broccoli and Brussels sprouts.

Trap Farming

Therefore, for companion gardening tomatoes, a long row of potatoes next to a long row of broccoli is not recommended. Routine crop rotation helps maintain proper soil conditions to completely avoid proper crops and soil-borne diseases.
