Trellis netting is a simple method to proving plants with support and structure in any garden. With 6 trellis squares on white nylon thread, HTG Supply has made it simple to provide your garden with a climbing or support net. For vining and climbing plants, you can hang this net …vertically to provide support to plants moving upwards. For plants with heavy flowers and fruits, a horizontal net will allow plants to direct more energy to their fruits and prevent falling branches.
