Soilless cultivation of the american highbush blueberry (Vaccinium corymbosum L.) is an alternative to soil cultivation, wherever the soil pH is not sufficiently low and there is lack of organic matter. Such a system is used in protected environments, but it is also applicable in open fields, where factors affecting growth and development of the blueberry can be adjusted and changed. Possible forms of soilless cultivation are planting in ridges or containers (pots). Additionally, different substrates (media) are used. Ridges help with water regime regulation if they are of the right height and shape but varying the planting distance is difficult. Containers enable precise control over substrate, nutrients and plant spacing, but smaller container volumes can have a negative effect on yield. Soilless cultivation systems can be upgraded with protected environments, for which early varieties are suitable. Cultivation in greenhouses or high tunnels results in increased air temperature, prolonged growing season and higher content of bioactive substances. The highbush blueberry grows best in a solid substrate, in a composted mixture of pine bark, coconut coir and peat moss. Suitable substrate pH values can be regulated by combining natural or artificially made mulches and sulfur preparations. Drip irrigation system makes the best use of irrigation water. Growers with the right choice of technology and choice of soilless cultivation method can design a profitable blueberry plantation.
