Thanks to their enormous size, sunflowers cast quite a shadow. In the middle of the day, when sunlight is most intense, it can bake and burn vegetable plants, but growing those plant under sunflowers' giant blossoms provides them with much-needed shade. Cucumbers and lettuce, for instance, can be grown beneath sunflowers to take advantage of the shelter they offer. Melons also need protection from the sun's harsh rays and grow well beneath sunflowers.
Some plants grow well together because they thrive in the same type of soil. Numerous bush bean varieties, such as wax, lima and green beans, are good sunflower companions for that reason. All of these plants are well-suited to acidic soil, with a pH level ranging from 6.5 to 7.5. Because bush beans provide their own nitrogen and don't require heavy amounts of nutrients, they don't compete with sunflowers for food, preventing the two kinds of plants from harming one another.
Though they are tiny, aphids are a serious problem for many plants, including flowers and vegetables. With their sharp, piercing mouths, aphids drain plants of their fluids can destroy entire gardens. Aphids also like to attack sunflowers, but they do little damage because of the sunflowers' thick stalks and overall toughness. If other plants suffer from an aphid infestation, plant a few sunflowers to act as distracting decoys.
Many plants, particularly those with long, winding vines, need trellises to support them as they grow. Although it’s possible to erect a store-bought, metal or plastic trellis, sunflowers are a natural, beautiful alternative. Vine cucumber and corn plants need support as they mature and can be trained to grow along sunflowers' stalks, which are strong enough to handle the other plants' weight.
