Plastic Trellis Clips Compared: Tested Grape Support Strength...Curb Gardening Stress! We recently tested the 400 Pcs Plastic Trellis Clips for supporting grape and tomato vines, and the results were quite promising. The clips are lightweight yet durable, making them easy to attach to stakes or cages without damaging our plants. We found that their plastic construction holds up well in various weather conditions, and the multiple clips allow us to customize support for different stages of growth. What impressed us most was how they keep vines upright, reducing the risk of breaking under their own weight. With 400 pieces, we’ve had no shortage of spare clips for new seedlings or replACEMENTS. While some fine-tuning is needed to prevent over-tightening, these clips are an excellent solution for maintaining healthier, more structured plants. Overall, they’ve significantly reduced our gardening stress this season.
