Set the plant at the same depth it grew in the nursery. Also, thoroughly water each blueberry plant. Highbush blueberries should be spaced 4 to 6 feet apart. A 3 to 4 foot spacing is adequate for the smaller half-high blueberries. Plant 2 or 3 blueberry varieties to insure adequate pollination and fruit set.
Blueberries have a shallow, fibrous root system.
Plants quickly become stressed during hot, dry weather. To help retain moisture and control weeds, apply 3 to 5 inches of mulch around blueberry plants. Sawdust, wood chips, pine needles, and shredded leaves are excellent mulching materials. During dry weather, water plants weekly. Blueberry plants should not be allowed to bear fruit the first 2 years after planting.
