Cultivation

''Vaccinium virgatum'' grows best on acid soil and is subject to few pests and diseases. Because it is not self-fruitful, two compatible varieties should be planted next to each other to maintain fruiting. If maintained with
mulch A mulch is a layer of material applied to the surface of soil. Reasons for applying mulch include conservation of soil moisture, improving soil fertility, fertility and health of the soil, reducing Weed control, weed growth, and enhancing the v ...
ing, it may endure temperatures as low as 10 degrees Fahrenheit. The plants mature to heights from 3 to 6 feet, with a width of up to 3 feet. The plant has few insect or disease problems, however birds and squirrels consume its fruit.
