The Benefits of Squash Companion Planting

Companion planting offers many benefits for squash plants. Some of these benefits include:

Similarly, planting herbs like thyme or basil near squash plants can deter pests like aphids and spider mites.

Increased Yields

Companion planting can also increase your yields by improving the health of your plants. For example, planting beans near squash plants can improve soil health by adding nitrogen to the soil. This can lead to larger, healthier squash plants with higher yields.

Another benefit of companion planting is that it can improve soil health. For example, planting legumes like beans or peas near squash plants can help fix nitrogen in the soil. This can improve soil fertility and make nutrients more available to your plants.

Natural Weed Control

Companion planting can also help with natural weed control. For example, planting groundcovers like clover or vetch near squash plants can help suppress weeds by shading the soil and preventing weed seeds from germinating.

Attracting Beneficial Insects and Pollinators

Finally, companion planting can help attract beneficial insects and pollinators to your garden. For example, planting flowers like zinnias or cosmos near squash plants can attract bees and other pollinators. Similarly, planting herbs like dill or parsley near squash plants can attract beneficial insects like ladybugs and lacewings.
