Tree & Plant Care

Highbush blueberries can reach 6 to 15 feet high.
Some plants are self-fertile but planting 2 plants ensures better fruit set. May take 4 to 8 years to produce fruits.
Best in sunny, acid  (pH 4.5 -5.5) , well-drained but moist soils with lots of organic matter. Will not produce in too alkaline soil.
Keep soil evenly moist, do not let dry out. Mulch to conserve moisture and moderate soil temperatures.
