Bird Netting 3/4" x 3/4" black polypropylene mesh. Our side netting is a perfect solution for growers not wanting to have the netting go over the top of the trellis. The netting is generally installed at the time of veraison. Some growers roll it up to a trellis wire and leave it there until the next season. This side netting only comes in 5,000' long rolls.
