How to Grow Blueberries Organically: A Step-By-Step Guide for Beginners

Besides producing sweet, healthy fruit, blueberry bushes are easy to grow and grow slowly to moderately. The blueberry plant can be planted directly in the ground, as landscape shrubs, or as potted plants to add color to your patio. In the fall, blueberry bushes turn a brilliant red color thanks to their pointed, oblong leaves that are leathery to the touch. Flowers appear in clusters of white, bell-shaped blooms in late spring, followed by delicious purple-blue berries that ripen from green to purple.

Types of Blueberries

Blueberry plants can be classified into four main types. Their size primarily classifies them, and plant breeders continue cultivating new varieties to improve their vigor. The main types include:

Highbush
Southern highbush
Lowbush
Half-high blueberries
Rabbiteye

Soil Requirements for Growing Blueberry Plant

Growing blueberries requires very acidic soil with a pH between 4.0 and 5.2. Blueberries also grow well in soil that contains a lot of organic matter. If your garden has heavy clay soil, raised beds with sandy soil are better than dense clay soil. Blueberries grow better in raised beds where the soil composition and pH can be controlled.

Sunlight Requirements for Growing Blueberry Plant

Like most fruit-bearing trees and bushes, blueberry bushes enjoy full sun and produce more fruit when they have more sunlight. There are a few exceptions, though. If you grow a northern variety in a hotter climate or live somewhere with extreme heat, your blueberry bush will appreciate shade during the hottest parts of the day.

If you live somewhere with strong winds, your blueberries will need some protection from them. This may interfere with how much sun your blueberries can get, but blueberry bushes are susceptible to wind damage. It’s better to protect your bush and have a marginally smaller harvest than to have no blueberries.

Temperature and Humidity for Growing Blueberry Plant

Blueberry bushes require different temperatures depending on their species. The traditional highbush varieties enjoy humid air and cold winters, while varieties bred for southern gardens cannot tolerate freezing temperatures. The majority of types prefer protection from drying winds.

Selecting a Planting Site for Growing Blueberry Plant

You should pick a location that receives full sun but is sheltered from strong winds. You should avoid planting near tall trees or shrubs that might block sunlight or compete for soil moisture and nutrients. Ensure that the planting site has good drainage. Planting holes should be well-drained, loose, and acidic to add peat moss. You can also grow blueberries in containers if you provide them with enough sunlight and moisture.

When to Plant Blueberry Plant

Blueberry bushes should be purchased as bare-root plants that are two to three years old. Older plants suffer more transplant shock and take more time to start producing large harvests. In general, blueberry bushes are planted between early and mid-spring. Those living in USDA Hardiness Zones 6 and higher can also plant them in the fall.

How to Plant Blueberry Plant

Blueberry seeds should be planted in seed trays filled with moistened sphagnum peat moss and covered with soil about 1/4 inches deep. Seedlings should be kept moist and allowed to grow in moss until they reach 2 to 3 inches tall. It may take 6 – 8 weeks for blueberry seeds to germinate and even three months.

The germination rate of your blueberry seeds will be enhanced if you chill them before planting. The starter trays should be kept between 15.5°C to 21°C with a germination mat if the daytime temperature is below 15.5°C. Your seedlings can be thinned out and transplanted into moist, acidic soil the following autumn when they reach about 2 inches tall.

Spacing, Depth, and Support

When planting blueberry bushes in a row, there should be ample room for harvesting at least nine to ten feet between rows. In the case of bare-root plants, spread the roots out into a prepared hole, then cover them with soil, ensuring that the root ball is not more than 1/2 inch below the soil surface. Blueberries grown in containers should be planted at the same depth in nursery pots. A blueberry bush does not usually require any support structure because it is sturdy.

Water Requirement for Blueberry Plant

Deep watering should be given to the plants at least once a week. The roots of blueberries are shallow, so they require at least two inches of water each week (more in dry weather). Additionally, you can use an automatic irrigation system to ensure that your plants receive consistent water.

Organic Fertilization for Blueberry Plant

Blueberries should not be fertilized in their first year. Until the plants are established, salt can cause root damage. You can begin feeding your blueberries after they have been planted for one year based on two main indicators: the opening of flower buds and the forming of berries. Blueberry bushes benefit from organic fertilizers such as bloodmeal and cottonseed. Using manure may damage the plant, so avoid it.

How to Prune a Blueberry Plant

Blueberries should be pruned annually in early spring or late winter. It would be best to prune canes at the ground when they reach a one-inch diameter (this could take around eight years). Each year, remove any dead branches or crossing branches. A cane with a 1/2 to 1-inch diameter produces the most fruit, and 16 canes are ideal. Highbush blueberries usually reach a height and width of 4-6 feet.

Organic Pest Control for Blueberry Plant

You may see some damage from small, leaf-eating insects that you can prevent using your favorite pest control method, but the main pests for blueberry bushes are birds. If you aren’t careful, birds pick your berries before you harvest the blueberries. The best way to keep birds, squirrels, and other blueberry thieves off your bush is to cover it with netting once the blueberries form. You can get bird netting at most gardening or home improvement stores.

Organic Disease Control for Blueberry Plant

Some fungal diseases can affect blueberries, including powdery mildew and rust (which can be treated with neem oil) and leaf spot diseases. Genetically resistant varieties are your best defense. Plants should also be given plenty of space for good air circulation, placed in full sun, removed debris, and mulch replaced annually so that fungal spores cannot overwinter. Using a fungicide labeled for edible plants might be necessary if you experience these problems.

Conclusion

Blueberries adapt well to organic culture. Production costs may be higher using organic methods, but premium prices can effectively counterbalance this. Many cultural practices, such as deep mulching and sodded row middles, work for conventional and organic blueberry production systems, offering a more sustainable approach to commercial horticulture.
