Companions can also be beneficial to add shade and windbreaks for plants not needing the late afternoon heat of the day such as beans, peas, corn, and cucumbers.  The shade of a plant can also act as a ground cover to prevent weeds and keep soil moisture by blocking the sun on the ground around the plant’s base.

Certain plants can add strong structures for plants to grow up such as corn, sunflowers, and other strong-structured plants.

I have been using companion plants in my vegetable garden for years which has not only improved the appearance of my garden but added beautiful scents as you walk through the garden as well as reduced the pests to attack my vegetables and fruit.
