Blueberry.com explains that caring for blueberries involves testing the soil to provide the correct fertilizer, mulching, watering and weeding. When the plants receive this type of care and full sun, they produce beautiful foliage and berries with a flavor and aroma that is unmatched by store-bought varieties, according to the National Gardening Association.
Blueberries require acidic soil, with a pH between 4.5 and 5.5. Ammonium sulfate and sulfur help to lower the pH of soil that is too high. If the soil is high in clay, it does not drain well, which can cause the roots to rot. Raised beds help to provide the necessary drainage.
Blueberries have a high need for water. Proper care involves regular watering along with providing four inches of mulch to reduce evaporation. Wood bark or other acidic mulch helps to ensure the soil pH remains low enough to encourage growth.
Because blueberries have shallow roots that heavy cultivation sometimes damages, they require gentle care to remove weeds that compete for moisture and water. Providing the required mulch helps to minimize the cultivation needed for these plants.
Blueberry-stem blight and birds are the greatest threats to blueberries. Gardeners can reduce the chances of blight if they stop fertilizing at the beginning of the blueberry harvest. Nets are effective at preventing birds from stealing the fruit, according to Southern Living Magazine.
