Blueberries are one of nature’s ways of providing you with a host of health benefits. According to the Berry Health Benefits Network, blueberries rank number one among 40 fresh fruits and vegetables when it comes to antioxidants, neutralizing free radicals that can cause cancer and other age-related diseases. Not only are blueberries good for you, but they provide a burst of flavor, making them a favorite in pancakes and muffins or served fresh with cereal. Growing them in your home garden requires relatively little care other than mulching, fertilizing and watering.

Water blueberries thoroughly, saturating the soil to the root level, when you plant them. This establishes roots quickly and reduces stress to the plant.

Mulch the area beneath blueberry plants with 2 to 3 inches of organic mulch, like wood chips or bark. This holds in moisture and keeps soil cool.

Check the soil often by inserting your finger to a depth of 1 to 2 inches. If soil feels dry, your plants require more water. Allow soil to dry slightly between waterings, as blueberries suffer if their roots remain in soggy soil.

Adjust your watering schedule to meet the needs of your blueberry plants. The amount of water required depends on soil conditions, drainage, size and growth of the plants, and weather conditions. Blueberries typically require the equivalent of 1 to 2 inches of water a week. If your area does not receive adequate rainfall, supplemental watering is necessary.

Cease watering in early September, after fruit harvest, unless the soil is extremely dry. Resume watering in the spring when new growth appears.


Mulch from wood products binds nitrogen in the soil when decomposing. When using wood products, test your soil often and apply additional nitrogen as needed.
