Blueberry - Duke (Northern Highbush)

Vaccinium corymbosum 'Duke'
USDA Hardiness Zones: 4-7


Duke blueberry is a heavy, consistent producer with an attractive, firm, light blue high quality berry. The berries are large. Duke blooms late but ripens early, which protects the blossoms from spring frosts. You can plant Duke Blueberry with Jersey Blueberry which is a cold hardy blueberry that produces a late season crop. Branches may droop to the ground when laden with fruit, prompting many gardeners to use a simple trellis as support. This bush tolerates a wide range of soil types, and the small to medium sized, sweet tasting fruit is a favorite for baking. Striking flame orange fall foliage color. Duke blueberries require at least 800 chill hours. They are self fertile but will produce better crops if planted with other highbush varieties.

USDA ZONES: Zone 4, Zone 5, Zone 6, Zone 7

How to Plant
STEP 1) First, decide on a planting location. Consider carefully what kind of sun, soil, and growing-space your tree or shrub will need.
STEP 2) Once you've located the perfect spot, the hole you are digging must be at least double the width and as deep as the root system you are planting.
STEP 3) Remove the plant from the pot and place the root ball in the hole. The top of the root system should be level with the ground. Before placing the tree or shrub in the hole, use your hands to gently break up the root system.
STEP 4) Once the plant is in place, backfill the hole with native soil and any leftover potting material.
STEP 5) Pack down the soil to eliminate any air pockets.
STEP 6) When finished, water thoroughly.
Care Guide

Blueberries need lots of sunlight and slightly acidic soil in order to thrive. If you want to create a hedgerow, plant blueberries 2-3 feet apart. Once planted, mulch 2-4 inches over roots. Heavily prune blueberries each year to encourage higher yields once the plant is established.
