Four Wire Trellis System

The four-wire trellis system consists of two eight-foot wooden posts spaced eight feet apart and four-foot-long lengths of half-inch-diameter galvanized wire with a hook on one end (available at garden centers) that are twist-tied to the wooden supports. Trellis systems are used for cane support with trailing and semi-erect cultivars to keep the fruit off the ground and erect cultivars that will grow tall before being cut. The placement of canes on a trellis increases solar exposure, air circulation, and spray penetration throughout the canopy. Planting will be easier to handle if a trellis system is used. Easier harvesting leads to cleaner picking, which reduces the attractiveness of picnic, sap, June, and Japanese beetles, which can be attracted by overripe and rotten fruit. Trellising can also help with florican eradication. Build trellises before the first harvest season.
