Blueberries are delicious and nutritious fruits, packing a healthy source of vitamins K and C, potassium, and manganese. Better yet they're easy to grow, so you can plant them in the ground as landscape shrubs or grow them in pots as a colorful addition to your patio or balcony.

Blueberries generally have a slow growth rate, taking about 10 years to reach its mature size. Additionally, you will have to wait at least two to three years before you start enjoying a bountiful harvest. Nonetheless, the reward is incredibly sweet and worth the wait.

So, learn the top tips to grow these tiny but mighty fruits in your garden.

1. Choose the Right Variety

You can choose from unique blueberry varieties with different fruiting times, growing sizes, hardiness, and compactness. They are divided into four broad categories you can grow in your garden.

• Northern Highbush: This variety grows well in northern areas such as the US and Canada. It includes 'Duke,' an early-season variety, 'Bluecrop,' a mid-season cultivar, and 'Brigitta,' which produces fruits late into the fall.
• Southern Highbush: Suited for warmer areas of the northern regions and needs cross-pollination. Some options include 'Suziblue,' 'Jubilee,' and 'Magnolia.'
• Rabbiteye: These cultivars require cross-pollination as well, so grow more than one plant. They grow better in southern states and include 'Austin,' with large, firm blueberries, 'Sharpblue,' with firm, dark blueberries, and 'Garden Blue,' with small, light blue fruits.
• Lowbush: Typically growing to about 18 inches tall, the berries have an intense flavor. 'Top Hat' and 'Ruby Carpet' are some of the lowbush cultivars.

2. Select a Suitable Location

Plant the berries away from trees, which can cast shadows, compete for nutrients, and hinder air movement. While they can tolerate light shade, too much shade can lead to fewer flowers and fruits.

Ensure the soil is well-draining and sandy, with an acidic pH between 4.5 and 5.5. Improve the planting area with aged manure or compost to aid soil drainage and add nutrients. If the soil in your garden is heavy clay or alkaline, it is better to grow bluebrries in containers (5 gallon pot) or raised beds, about 6 to 8 inches high.

3. Maintain the Soil Acidity

Soil acidity is one of the most important parameters to monitor for blueberries. If you notice yellow leaves on the blueberry bush, it can indicate a lack of acidity.

Check the pH with a soil test the previous fall before planting blueberries. If the ground is only slightly acidic, treat it with sulfur chips or peat moss to lower the pH. Just before planting, you can also amend the soil by adding in acidic organic matter, like bracken, pine needles, leafmold, or composted conifer bark.

Mulch with rotted sawdust, pine needles, wood chips, or shredded leaves to maintain the lower acidity as they decompose. Taking the time to mulch your blueberry plants will also keep their shallow roots cool and helps the soil retain moisture.

4. Plant Them Correctly

Blueberries are planted as small, bare-root shrubs that you can order online or buy from your local nursery. It is best to plant them in the ground as soon as you receive them in early spring.

Start by digging a hole in the ground that is slightly deeper than the nursery pot and thrice as wide. Water your blueberry plant in the pot thoroughly and tip it out gently. Place it in the hole and backfill the soil, firming it in place.

Space the plants 3 to 6 feet apart, depending on the variety. Ensure you do not plant them deeper than the depth of the pot they grew in at the nursery. Water well and mulch using a 2 to 4-inch thick layer (with the above mentioned materials), leaving some space around the stem base.

5. Water and Feed for Success

Water your blueberry shrubs regularly to maintain the moisture level in the soil so they produce abundant fruits. A thorough, deep watering once a week should do the trick, but you may have to water more during hot, dry spells.

Once the berries start developing, they require 1 to 2 inches of water weekly. If there has been insufficient rainfall, irrigate the plants manually. Collect rainwater for manual irrigation since tap water can be too alkaline.

Blueberries can benefit from fertilizing once when the leaf buds start swelling and again when the fruits begin to form. Use an organic acid fertilizer, like the one recommended for rhododendrons and azaleas.

6. Prune Yearly

Pruning helps encourage new growth and keeps the plants in top shape. Prune once annually when the plant is dormant, ideally between February and March.

Remove branches that are dead, diseased, or touching the ground. Also, prune a quarter of old, thick stems, as well as young stems that failed to ripen the previous year. Avoid pruning too aggressively, which can reduce the yield.
