SA Witlof grower imports roots to better service local market demand

Jun 14 2017 15:44

Cape Town - With its two-stage growing process, Witlof, also known as Belgian Endive, has a production cost higher than many other leafy vegetables.

One of the factors contributing to the higher unit price, which is similar to artichokes or asparagus, is that the Witlof seeds need to be imported from The Netherlands and then, in South African soil, yields poorly. Sometimes less than a third of the planted seeds produce roots that can be used for the second stage of Witlof production.

“Once the Witlof roots are harvested from the earth, they are frozen until required for the second growing stage, this time, entirely in the dark, hydroponically in a nutrient-rich water solution,” says Fanie van der Merwe of Bronaar Farms in Ceres in the Western Cape.

Van der Merwe explains that the reason why the Witlof leaf is a creamy white is that the sun hasn’t developed the green-coloured chlorophyl that typically occurs during photosynthesis. Also, unlike many other leafy vegetables that are grown in soil, the Witlof chicon, the name for the head that grows from the root, is perfectly clean.

“Because of the low-yield of roots grown in South Africa we are now importing roots directly from The Netherlands and then growing the Witlof chicon in our R7m purpose-built hydroponic facility in Ceres,” Van der Merwe explains. “It takes three weeks from putting the root in the nutrient solution before the Witlof chicon is ready to harvest. This means we can accurately plan a calendar of supply to the supermarkets like Woolworths, Food Lover’s Market, Checkers and others that carry our Witlof."

In agricultural sales terms, the packout is the number of items ready for sale from the volume planted.

"In Europe the benchmark for Witlof packouts is 80kg/m2 and yet in our facility we are nearer to 50Kg/m2. The plan is to increase this percentage and, we believe, that we will off-set the costs of importing the roots via shipped refrigerated containers, to give us a higher packout and increased volume into stores,” he says.

Although Witlof has been grown in South Africa before, and also imported as a finished product, Van der Merwe’s facility is the first to be able to supply Witlof for 12 months of the year and already has capacity for four-times the current volume.

“We are pleased about the increased demand, already proven in the few short months of our Witlof promotion campaign, and we look forward to meeting increased demand in the future,” he says.
