Van Voorthuijsen nurseries in Randwijk has the first movable anti-hail netting in the Netherlands. It is also the first anti-hail netting to be used above ornamental and avenue trees.
Van Voorthuijsen specialises in grafting and cuttings for tree growers, which means that on a relatively small area of one and a half hectares, there are about 40,000 grafts and cuttings in growing gutters. A heavy hail storm could destroy everything in one fell swoop.
The aim is to prevent their plant material from being damaged by storms, heavy showers and hail.
The anti-hail netting, which is as strong as a tow rope, is made of finely woven plastic mesh that turns large raindrops into light drizzle and stops hailstones. This solar-powered netting system can open or close automatically within 10 minutes.
