Plants release chemical substances that can affect or benefit other plants, this effect is known as allelopathy, which we can use in our garden to facilitate their self-regulation processes. If we plant at the same time and space plants that work well being close, it is possible to obtain benefits such as cooperation in the uptake of nutrients, better growth, increased resistance to external factors, greater ecological control of insects and diseases.
To obtain these results the most important thing is to know the needs and characteristics of each of the plants that we want to have in our garden, considering the following general rules of association: Sow together plants that prefer similar conditions. Fast-growing plants with slow-growing ones. Tall plants with others that require shade. Keep separate those that are susceptible to the same insects and diseases. Finally, it is recommended to integrate medicinal herbs such as basil, chamomile, calendula, nettle and garlic for pest and disease control in all gardens.
