Important Steps to Plant & Grow Blueberries Successfully

| Plant, Video

Once established, blueberries are easy to grow and require little care, but there are things you need to know at planting time for long-term success. In this video, I share tips for ensuring your blueberry plants will thrive.

 

 

Blueberries are one of my favorite plants to grow. In addition to producing amazing fruit, they offer three seasons of ornamental value. They make a great addition to an edible garden but will look great anywhere sunny.

Choosing Blueberry Plants

There are several types of blueberries to choose from: highbush, half-high, lowbush and rabbiteye. 

Highbush blueberries grow 5-6 feet tall and will spread just as wide. Generally, they grow best in zones 4-8. To get more specific, there are northern highbush types and southern highbush types, with the southern types being less cold tolerant. A good local garden center will only sell the type that is suited to your region. 

Half-high blueberries grow about 2½ feet tall and 2 feet wide. Some varieties, under the right conditions, will produce two harvests a year. Half-high, like highbush, is hardy in zones 4-8. 

Lowbush blueberries are the predominant type in New England. These are the smaller, wild blueberries that reach 1-3 feet high in zones 3-8 and are tolerant of colder climates.

Rabbiteye blueberry plants are best suited to zones 6-9, in the South and West, and are known for their heat and drought tolerance. These reach 15-18 feet tall and spread 5-6 feet wide. Rabbiteye varieties are also more tolerant of poor soil conditions.

Keep in mind that for efficient pollination — and more production and yield as a result — you’ll need to plant two to three varieties from the same blueberry family together. Blueberries are also classified as early-, mid- and late-season varieties. By planting a few of each, you can get consecutive blueberry harvests for weeks on end.

There are several varieties of blueberries to choose from, and different types produce yields at different times of the year. Plant a few of each, and you’ll have consecutive blueberry harvests.

 

Acidify Soil for the Best Performing Blueberry Plants

Blueberry plants, like all plants that bear fruit, require full sun and well-draining soil. What sets blueberries apart from most plants is they love acidic soil — soil with a low pH. Neutral soil has a pH of 7.0, while blueberries prefer a pH of 4.0 up to 5.5 at the highest.

To determine the soil’s pH level, you will need a soil test. The results will tell you what you are starting with, and then there are a few ways to get that pH level where it needs to be.

To lower the pH, soil test results will likely recommend a sulfur-based soil acidifier. You can find such products at just about any garden center. Be sure to closely follow the instructions on the bag to get the desired effect. 

You can also take the natural route: Finely ground shredded pine bark mulch, pine bark nuggets or peat moss will all lower soil pH. These inputs should be mixed into the entire growing area for the roots to get at. 

Once your chosen soil amendments have had a chance to work their way into the soil, it doesn’t hurt to get another test to determine if the pH has hit the mark.

Blueberry plants thrive in acidic soil — soil with a low pH. Neutral soil has a pH of 7.0, while blueberries prefer a pH range of 4.0 up to 5.5.

 

How to Plant Blueberries

The ideal time to get blueberry plants into the ground is from fall to early spring. Be conscious of how large the plants will be when they reach maturity, and space them out accordingly.

To set blueberry plants up for success, dig a planting hole that is two to three times wider than the root ball, but no deeper. Set the plant in the hole with the base of the stem above ground level. Then backfill the hole with plenty of acidic organic matter, and water in.

After the blueberry bush is planted, apply 2-3 inches of acidic organic mulch, such as partially rotted leaves, rotted pine needles, or finely ground pine bark. Acidic natural mulch will retain moisture, acidify the soil and provide nutrients as it breaks down.

Blueberries have a shallow root system and are susceptible to weed competition — another reason why mulching is a can’t-skip step.

When planting a blueberry bush, be sure the hole is 2-3 times wider than the root but no deeper. Backfill the hole with plenty of acidic organic matter before watering in.

 

How to Water Blueberries

As mentioned above, blueberries need well-draining soil. However, blueberries do enjoy plenty of moisture. The soil should stay as wet as a wrung-out sponge. I find a drip irrigation system is ideal for this. An inch of water during the course of a week is what to aim for.

Blueberries enjoy plenty of moisture. Water them in well after planting and then apply drip irrigation to supply the soil with the right amount of moisture.
