Blueberries are small, blue-purple fruits rich in vitamins C and K, manganese, and antioxidants. They can be eaten as a snack or used in various recipes, but growing them requires highly acidic soil and patience, as they take about six years to start producing.
Blueberries are fruits produced by the shrubs of the same name. As the “blue” in the name suggests, these small, round berries have a very distinctive blue-purple color. This North American fruit can be used in many different ways in cooking, and during late spring and early fall, blueberries are often readily available in produce markets. Blueberries can also be grown at home, although there are some special requirements to keep in mind when growing blueberries.
Blueberries have a sweet, slightly tart flavor and are widely rich in vitamins C and K along with manganese and antioxidants, leading some people to label them a “superfruit.” They range in size from the tip of a little finger to the tip of a thumb, depending on the cultivar. Once harvested, blueberries will keep for 7 to 10 days in the refrigerator, although they can also be frozen for future use.
Some people like to eat blueberries out of hand as a snack. These berries can also be added to fruit salads, eaten with yogurt and granola, sprinkled on cereal, and baked into pies. Some people like to make cranberry preserves, while others press the berries for their tart juice. Blueberries shouldn’t just be eaten with sweet foods. Blueberry jelly, for example, can accompany various roasts as a condiment. Cranberries can also be added to quick breads, scones, muffins and other baked goods.
Blueberry bushes ripen very slowly, generally taking about six years to really start producing. They don’t require much space, which can be an advantage in a small garden, but they do need highly acidic soil, and this sometimes poses a problem. In areas with naturally acidic soil, blueberries will, of course, thrive, but in other cases, the soil needs to be amended regularly to keep it acidic and can sometimes cause problems for nearby plants.
Blueberries are hardy in USDA zones two through six and once established, they usually do very well, as long as the soil acidity is kept high. Some people like to screen blueberries with netting to keep birds away from the fruit as it develops, and in cooler areas, it may be necessary to wrap blueberries at night in case of frost. Older bushes may require pruning in the winter while the plants are dormant to promote healthy, even growth.
