Plant Spacing

Plant spacing is based on the ultimate width of the plants. This figure is normally given as a range; for example, 3-5’. If you live in a cold climate and/or want plants to fill in more quickly, plan to space at the shorter end of the range. If you live in a warm climate, are on a limited budget, or are willing to wait longer for plants to touch, use the higher end of the range. Using the larger number is recommended when calculating distance from a building or structure. There’s really no such thing as "maximum spacing": if you don’t want your plants to touch, you can space them as far apart as you’d like. All plant spacing is calculated on center, or in other words, the centers of the plants are spaced one half of their eventual width apart:

bush distance

Unless you are planting in a straight line, as you might for hedges or edging, space your plants in a staggered or zig-zag pattern for a more interesting and naturalistic look:

More Information

Description ‘Duke’ blueberry plants boast high yields of firm, mildly tart dark-blue fruits come harvest season. This hardy blueberry shrub produces fruit a little earlier in the season than other varieties, around late June to early July, and is especially popular in the Mid-Atlantic region: Semi-evergreen and an excellent choice for beginner gardeners looking to grow fruit. Try ‘Duke’ blueberries in a delicious smoothie or freeze to enjoy their classic flavor year-round!

Wondering how to grow blueberries in your garden? There are a few key requirements for success! ‘Duke’ blueberry, like other blueberries, only grows in acidic soil (pH 4 to 5.5). Growing them in basic soil will lead to discoloration and low berry production. If your garden isn't acidic, don't worry. Just use organic acid fertilizer (like azalea fertilizer) or sulfur to adjust the pH. Growing them in containers makes this even easier! Make sure they're watered frequently and deeply to keep the soil moist. Learn more on how to grow blueberries in the "how to grow" tab. Details Botanical name: Vaccinium corymbosum 'Duke'
Common name: Blueberry, High bush blueberry
Zone: 5 - 8
Sun exposure: Full sun (6+ hours sun) to part sun (4-6 hours sun)
Height x width: 5-7' tall and wide
Flower color: White
Foliage color: Green
Season of interest: Late summer
Bloom time: Late spring
Features: Native, heat tolerant, fall color, container plants, cold tolerant, wet soils
Uses: Edible garden, container plant, native garden, hedge, specimen How To Grow Soil: Requires acidic soils (pH 4 to 5) that are well-draining and high in organic matter. Test your soil pH before planting, as soil that is not acidic will discolor leaves, slow growth, and kill the plant.
Light: Thrives in full sun (> 6 hours sun) but tolerates part sun (4-6 hours sun).
Water: Keep the soil moist but not too wet. We suggest watering frequently and deeply.
Spacing: minimum 3 feet apart
Fertilizing: In spring, apply an organic acid fertilizer, like those recommended for azaleas. If leaves are discolored or growth is slow, test the soil and apply more fertilizer or sulfur-based soil amendment.
Winterizing: Apply a thick layer of mulch around the base of the plants for insulation. Do not prune before winter.
Maintenance & pruning: Prune plants in early spring before growth starts to promote vigorous growth. Fruit is only produced on one-year-old wood, which means stimulating new shoot growth each spring is required for more berry production. However, pruning too aggressively will have the opposite effect.

I placed my first order with Great Garden Plants and kept it small to be sure that I love the plants! Well, they are beautiful! So well packed and they all looked amazing. They are planted and now only have to wait until Spring 2024 to see the results! Meanwhile, I couldn't resist and have placed another order double in size! When they come in, I will be busy getting them in as well! Thank you for your dedication to we gardeners!
