Blueberry - Duke (Northern Highbush)

Directions for Planting and Care

Planting and caring for your Blueberry - Duke (Northern Highbush) is simple and rewarding. With proper attention, this early-season variety will provide abundant, flavorful berries year after year.

Planting

Select the Right Location: Choose a sunny location with at least six hours of direct sunlight per day. Duke blueberries thrive in full sun and require good air circulation to reduce disease risk.

Prepare the Soil: Blueberries prefer well-draining, acidic soil with a pH between 4.5 and 5.5. If your soil is too alkaline, amend it with sulfur or organic materials like peat moss or pine bark to lower the pH and improve soil texture.

Dig a Proper Hole: Dig a hole twice as wide and just as deep as the root ball. This ensures that the roots have enough space to establish themselves.

Plant the Blueberry Bush: Carefully remove the plant from its container, gently loosen the root system, and place it in the center of the hole. The top of the root ball should be level with the surrounding soil. Backfill with the native soil and lightly pack it down to remove air pockets.

Water Thoroughly: After planting, water generously to help settle the soil and ensure the roots receive adequate moisture.

Mulching: Apply a 2 to 4-inch layer of mulch, such as pine bark or wood chips, around the base of the plant. Mulch helps retain moisture, regulate soil temperature, and suppress weed growth.

Care

Watering: Blueberries need consistent moisture, especially during dry spells. Water deeply at least once a week to keep the soil evenly moist but not waterlogged.

Pruning: Prune Duke blueberries annually in late winter or early spring to encourage strong growth and high fruit yields. Remove any dead or weak branches and thin out overcrowded areas to allow better air circulation.

Fertilization: Use a fertilizer formulated for acid-loving plants in early spring to promote healthy growth and fruit production. Avoid high-nitrogen fertilizers, as they can encourage excessive leaf growth at the expense of fruit development.

Spacing and Growth: If planting multiple bushes, space them 2 to 3 feet apart to create a hedge or 4 to 6 feet apart for individual plants. Mature plants typically reach 4 to 6 feet in height and spread 3 to 4 feet wide.

With proper planting and care, the Blueberry - Duke (Northern Highbush) will reward you with delicious, firm, and sweet-tart berries, perfect for fresh eating, baking, and preserves. Enjoy the beauty and productivity of this reliable variety in your garden!
