Tomatoes and Basil
One of the most popular plant combinations for companion planting is tomatoes and basil. This dynamic duo not only enhances the flavor of your harvest but also provides mutual benefits that promote a healthier garden.
Why This Combination Works:
Enhanced Flavor: Basil is known to improve the taste of tomatoes when grown nearby. Many gardeners swear by this pairing for its culinary benefits.

Consider adding a layer of mulch to retain moisture and suppress weeds, which can compete with both carrots and onions.
Pairing carrots and onions, you create a companion planting combination that not only maximizes garden space but also enhances pest resistance and soil health. This partnership is a great way to boost your garden’s productivity while reducing the need for chemical interventions.
The Three Sisters (Corn, Beans, and Squash)
One of the most iconic plant combinations for companion planting is the Three Sisters: corn, beans, and squash. This ancient Native American planting method is a perfect example of how plants can work together to create a thriving, sustainable garden ecosystem.
Why This Combination Works:
Structural Support: Corn provides a natural trellis for beans to climb, reducing the need for additional supports.
Nitrogen Fixation: Beans are legumes that fix nitrogen in the soil, enriching it and benefiting the nitrogen-hungry corn and squash.
Ground Cover: Squash plants spread out with their large leaves, shading the soil, retaining moisture, and suppressing weeds.
How to Plant Them Together:
Start by planting corn in a mound or hill. Once the corn is about 6 inches tall, plant beans around the base of the corn stalks.
A week or two later, plant squash around the perimeter of the mound. The squash will spread out and cover the ground.
Ensure the soil is rich in organic matter and well-drained. Water regularly, especially during dry spells.
Tips for Success:
Choose varieties that are well-suited to your climate and growing conditions.
Monitor for pests, as the dense planting can sometimes attract insects. However, the diversity of plants often helps deter pests naturally.
Rotate the Three Sisters to different parts of your garden each year to maintain soil health and prevent disease buildup.
