Zimbabwe’s expanding blueberry industry is using a combination of high-altitude growing conditions and precision drip irrigation to supply premium export markets during a global off-season window, according to Netafim Southern and East Africa agronomist Christo van der Westhuizen.

Van der Westhuizen said Zimbabwe’s production period, typically from May to October, falls at a time when supply from several major producers is limited, creating an opportunity for higher prices if growers can meet strict export quality standards.

“Zimbabwe produces world-class blueberries during a key global off-season window, when few competitors supply high-quality fruit,” Van der Westhuizen said. “This timing allows access to premium markets like Europe and increasingly China at higher prices, with strong demand when major producers have low or no supply.”

Van der Westhuizen also described how precision irrigation technologies are increasingly important for high-value horticulture. He said blueberries have shallow, sensitive roots and require consistent moisture, low soil pH and accurate nutrient delivery, making uniform irrigation a key factor in maintaining fruit quality.

“Blueberries have shallow, sensitive roots that need consistent low soil pH, uniform moisture, and precise nutrient delivery without excess water or dry spells,” he said.

He added that irrigation technology needs strong after-sales support to ensure correct installation and ongoing agronomic guidance. He also warned that inadequate maintenance can reduce system uniformity and lower yields, recommending regular flushing, filter checks, pressure monitoring and timely repairs.

On daily irrigation scheduling, Van der Westhuizen advised growers using potted systems to irrigate based on drainage targets. For in-soil plantings, he recommended checking moisture levels in the shallow root zone using tools such as a soil auger or probe, and timing irrigation to avoid both dry stress and overwatering that can lead to leaching, nutrient loss or root rot.

As Zimbabwe’s blueberry sector grows, he said precision irrigation and consistent monitoring are increasingly central to profitability for farmers targeting export markets where quality and reliability determine returns.

“Precision irrigation, proper maintenance and consistent monitoring are essential if you want to produce high-quality fruit and maximise returns,” Van der Westhuizen said.
