Blueberry cultivation is undergoing a shift as growers seek innovative solutions to improve plant performance and fruit quality. Recent trials and commercial plantings in South Korea and other regions have highlighted the benefits of advanced substrate blends, particularly those developed by ASB Professional. "Our medium, composed of Baltic peat moss, wood fiber, and perlite, is demonstrating remarkable results in containerized blueberry production," Olesia Klimchuk, Export Manager at ASB Professional, emphasizes.

She notes the importance of substrate composition for sensitive crops like blueberries. "Blueberries are particularly demanding when it comes to soil structure, drainage, and acidity. Our substrate blends are designed to create a stable, well-aerated root environment that supports vigorous growth and high-quality fruit."
The ASB Professional medium uses the complementary properties of its components. Baltic peat moss provides a naturally acidic pH and excellent water-holding capacity, crucial for maintaining steady moisture without waterlogging. "By integrating Baltic peat moss, we ensure that the plants' root zone remains consistently moist yet aerated; conditions that are ideal for blueberry health and nutrient uptake," she says.
Wood fiber contributes structural integrity and enhances oxygen availability in the substrate. Its fibrous texture prevents compaction, promoting healthy root respiration and improved drainage. "Wood fiber is essential for maintaining a loose, well-structured medium. It allows excess water to move freely while retaining enough moisture for optimal plant growth."
Perlite, a lightweight volcanic mineral, further enhances aeration and drainage. When combined with wood fiber, it creates a porous root environment that minimizes stress and supports vigorous root development. She points out, "The synergy between wood fiber and perlite ensures the substrate remains stable and well-structured throughout the growing season, even under intensive production conditions."

Growers in South Korea report particularly impressive results using this combination. Container-grown blueberries exhibit rapid establishment, strong vegetative growth, and prolific flowering. The optimized root conditions allow plants to absorb nutrients efficiently, maintaining consistent growth and performance. "Our customers have observed not only improved plant vigor but also a remarkable increase in flower and fruit production."
Fruit size is a standout benefit of this substrate solution. In several commercial plantings, blueberries cultivated in ASB Professional medium consistently exceed 28 millimeters in diameter, placing them in the premium market category. "Larger berries enhance both market value and consumer appeal. Substrate management plays a key role in achieving these uniform, high-quality fruits."
The advantages extend beyond South Korea. In other blueberry-producing regions transitioning toward containerized or substrate-based cultivation, ASB Professional medium allows growers greater control over irrigation, fertilization, and root health. "Our substrate provides a reliable foundation for growers who want predictable yields and consistent berry quality."
ASB Professional will showcase its advanced growing media at Greentech Americas, where industry professionals can learn more about substrate innovations and observe firsthand the latest results in blueberry cultivation.
