How to Grow Blueberry
Vaccinium corymbosum
Blueberries are perennial shrubs prized for their sweet fruit and ornamental appeal. Gardeners grow them for reliable yields of nutritious berries that thrive in acidic soil conditions.

🌾 Sow directly in the garden — Blueberry is not usually started indoors.
Established shrubs are moved outdoors after the last frost once soil temperatures have warmed sufficiently for root growth.
Soil, care & harvest
Prepare well-draining soil with a pH between 4.5 and 5.5, as blueberries require highly acidic conditions to flourish. Since these are perennial shrubs grown from bare root or container stock rather than sown seeds annually, select plants after the last frost when outdoor temperatures stabilize. If propagating from seed, start indoors 12 weeks before the last frost for optimal germination rates.
Space plants 4 to 6 feet apart to allow proper air circulation and root development. Water consistently to maintain moderate moisture levels, as shallow roots are sensitive to drought. Apply a layer of acidic mulch around the base to retain water and suppress weeds, while feeding with specialized fertilizer designed for ericaceous shrubs.
Watch for spider mites and leaf blight; prevent issues by ensuring good airflow and avoiding overhead watering. Harvest ripe berries in late summer when they turn deep blue and detach easily from the stem. Pick fruit regularly to encourage continued production throughout the season.
