What Are Blueberry Companion Plants?

Some blueberry companion plants include begonias, early-blooming primroses, lily-of-the-valley, gladiolus, hyacinth, tulips, mountain laurel, heather, andromeda, Hartford fern, hay-scented fern, upland lady fern and doghobble. Because blueberry plants require such a low pH, only other plants that tolerate acidic soil can be used as companion plants. Companion plants also need growing conditions similar to those required by blueberries.

A blueberry plant makes a great garden or ornamental plant. If planted in a garden, companion fruit and vegetable plants can include rhubarb, raspberries, cranberries, potatoes, parsley, endive or peppers. The gardener needs to remember that the first three plants are perennials, which means that they come back every year.

A blueberry plant can also be used as an ornamental shrub. Rhododendrons, azaleas, camellias, summersweet and fothergilla are great shrubs to plant alongside blueberries. Some perennial plants include bunchberry and bleeding heart.

A blueberry plant not only needs acidic soil in order to thrive, but the soil also needs to be well-drained. The plant needs plenty of sunlight, especially during its growing season. Every year the plants need at least six weeks of cold weather. If the gardener is planting more than one blueberry plant, they need to be spaced 4 to 5 feet apart in order to give them space to grow.
