The Benefits of Companion Planting

Companion planting is the practice of planting certain plants together to benefit each other. There are several benefits to companion planting, including:

Natural Pest Control

Certain plants have natural pest-repellent properties that can help keep pests away from your squash plants. For example, marigolds are known to repel nematodes, while garlic is a natural insect repellent.

Increase Soil Fertility

Some plants are known to improve soil fertility by fixing nitrogen or adding organic matter to the soil. This can help your squash plants grow stronger and healthier. Examples of such plants include clover and beans.

Provide Shade

In hot climates, some plants can provide shade to your squash plants, helping to prevent sunscald and other heat-related damage. Examples of shade-providing plants include corn and sunflowers.
