Companion planting is a permaculture technique that increases garden yield and productivity by planting different crops in the same bed. Choosing good “companions” to plant together while avoiding bad combinations is the key to getting the most out of you land this year.

Sweet corn requires large amounts of nitrogen, and will grow better when inter-planted with nitrogen fixers. Climbing beans, corn, and squash (aka “the three sisters”) is a classic trio of companion plants. Corn stalks will support climbing beans while they fix nitrogen. Squash provide ground cover and fill in the bottom story of the mini ecosystem.
Planting sunflowers with corn is said by some to increase the yield. Soybeans deter chinch bugs.
Tomato worms and corn ear worms feed of both plants, making them more prone to disease when planted together.

Fennel should not be planted near most annual garden varieties. Cucumbers encourage blight on late variety potatoes. Nut trees are toxic to tomatoes. Raspberries should not follow eggplant, tomatoes, potatoes, peppers, or other raspberry varieties in the crop rotation. Wormwood is best grown away from other plants.
What are some examples of companion planting?
The classic companion planting example is corn, pole beans, and squash. Corn supports the beans, which provides nitrogen to the corn, and shades the squash which provides ground cover. Tomato and basil are very popular companions to plant together.
