Blueberry Plant Facts


Blueberry plants grow into small, compact bushes between 4 and 6 feet in height and 3 to 4 feet in width. Blueberries grow quite slowly, and you won't see any fruit until the plants are at least 3 years old, but the older they get the larger they grow and the more fruit they produce. Blueberry plants are attractive plants that produce tiny flowers in early spring and give you showy orange and red colors in fall. As your plants mature and start producing berries, you'll find they're a huge attraction to all types of birds, too.


Blueberries like soil enriched with organic material. The soil should be well drained and sandy or loamy, with plenty of mature compost mixed into the top several inches of soil. North Carolina State University states there must be at least 2 percent organic matter in the soil, and Ohio State University Extension recommends at least 4 percent.

Water and Sun

Blueberries need well-drained soil so that the roots don't drown, and in the first year of planting the soil needs to be kept moist at least halfway down to the plant roots. To get the greatest amount of fruit from your blueberry bushes over the years, plant them in full sunlight. They'll tolerate up to 50 percent shade, but the more shade they have, the slower they will grow and the less fruit they'll produce.

pH Levels

Blueberries are very particularly about the soil pH levels. They like acidic soil with pH levels at 4 to 4.5, and it's extremely important to test the pH levels of your soil before making any adjustments and again before planting. Adding peat moss, pine needles and oak leaves or bark will help lower the pH levels and greatly improve your blueberry planting results.


Blueberry plants need at least 160 days in their growing season, and both plants and fruits can be damaged by a frost in late spring or early autumn. Blueberries are rated for growing from U.S. Department of Agriculture hardiness zone 4 and above, but they're not good for growing in areas that drop below -20 degrees Fahrenheit. The plants will produce white or pink flowers in early spring, and fruit bearing plants will be ready for harvest in midsummer.

Fruit Production

Blueberries don't produce fruit in their first two years, and only a small amount of fruit starts coming in the third year. Fruit production continues increasing until the sixth or seventh year when the plants are considered fully mature. When taken care of well, blueberry bushes can continue producing fruit for 15 to 20 years.
