Highbush Blueberry ‘Duke’

‘Duke’ Highbush Blueberry (Vaccinium corymbosum ‘Duke’). Vaccinium corymbosum ‘Duke’ is an early highbush blueberry highly valued for its consistent productivity and firm fruit quality. This deciduous shrub develops an upright, structured habit, slightly taller than wide, making it ideal for fruiting hedges and row plantings. In spring, an abundant display of pinkish-white bell-shaped flowers attracts pollinators and precedes one of the season's earliest harvests. The blueberries, medium to large in size, are firm, sweet, and slightly tart, excellent for fresh consumption and preservation.

To plant ‘Duke’ highbush blueberry, choose a suitable exposure: full sun. The recommended soil is: acidic, rich in organic matter, well-drained. These plants require acidic soil and consistent moisture. Check the pH before choosing amendments; foliage color alone is not sufficient to diagnose a specific need. Avoid liming and protect the shallow roots when weeding. Water the root ball before planting and ensure water can drain after planting. During establishment, check the soil moisture by hand before watering again.

Allow a width of 1.5 m (5 ft) when planning the plant’s space in the garden. The indicated height of 1.8 m (6 ft) helps in choosing its position relative to neighboring plants. Maintain access to the base for weeding, checking moisture, and removing damaged parts. Pair this variety with plants that have compatible light and water needs. If you are considering a container, first verify that its volume and drainage are suitable for root development. Roots in pots are more exposed to cold than those planted in the ground.
