Basil acts as a natural pest repellent for tomatoes, helping to ward off flies, mosquitoes, and even aphids. Its strong aroma confuses and deters many garden invaders, keeping your tomato plants safe. In return, the tomatoes provide basil with much-needed shade, protecting the delicate leaves from the hot summer sun.

To get the most out of this dynamic duo, plant your basil plants about 12 inches away from your tomato plants, allowing enough room for both to thrive. Keep the soil consistently moist, as both plants prefer well-drained, nutrient-rich conditions. With a little care and attention, you’ll be rewarded with tastier tomatoes and a bountiful basil harvest.

Corn, Beans, & Squash

If you want to maximize your garden space and create a self-sustaining ecosystem, consider the classic “Three Sisters” planting method. This ingenious technique, rooted in Native American tradition, involves growing corn, beans, and squash together in a mutually beneficial arrangement.

The corn provides a sturdy stalk for the beans to climb, while the beans, in turn, help fix nitrogen in the soil, nourishing the corn. The large, sprawling leaves of the squash plant create a living mulch, shading the soil and preventing weed growth. This trio works in perfect harmony, each contributing to the overall health and productivity of the garden.

To try the Three Sisters method, plant the corn first, allowing it to establish a solid foundation. Then, plant the beans around the corn stalks, letting them climb up for support. Finally, tuck the squash plants in the spaces between the corn and beans, making the most of your available real estate. This ancient planting technique can yield a bountiful harvest of flavorful vegetables with patience and care.

Marigolds & Most Veggies

Marigolds are the unsung heroes of the vegetable garden. These bright, cheerful flowers are a feast for the eyes and act as natural pest repellents, protecting your plants from a wide range of unwanted critters.
