Benefits Of Basil Companion Plants

Companion planting is also known as intercropping. With proper and judicious use of space, one can significantly impact basil’s growth and harvest quality. However, there are numerous benefits of growing companion plants. The advantages are as follows:

  1. Repel Insect Pests: Sometimes, plants have their natural ability to kill those toxic and potentially dangerous toxins which are least affected by insecticides. In such cases, companion plants are helpful.
  1. More Soil Nutrients: While growing, the plants consume the nutrients in the soil, thereby exhausting it. This exhaustion leads to additional pressure on the gardener. In such cases, the companionship of plants such as beans and legumes will prove beneficial by replenishing the soil’s nutrients.

While growing your plant in a place where sunlight is in excess, you can look for tall plants with big leaves as your companion plants. Asparagus and zucchini can turn out to be the best companion plants in these cases.
  1. Improves Ground Cover: Some plants don’t cover much soil cover due to which excessive sunlight can harm them. In such cases, you can use layering crops such as oregano which increases the ground cover of the plant by optimizing the amount of sunlight and temperature.
  1. Brings Home Beneficial Insects: Sometimes, companion plants such as marigolds can bring home a bunch of pollinators such as birds, bees, and butterflies. As a result, the pollination chances and amount of harvest increase significantly.

Not just this, companion plants can be beneficial in other ways too. Using fast-growing and slow-growing plants as companions will help in differentiation and improvement in the growth of the original plant.
