Great for grafting larger stock! The practice of grafting vegetables onto root stock of highly disease resistant varieties has become increasingly popular in recent years, especially in high tunnel production. By grafting your favorite varieties onto disease tolerant rootstock, you can get the flavor you love while achieving improved disease protection and hardiness. Grafting has been shown to improve crop health, yield, and disease resistance. These spring loaded clips are great for larger stems 1/8" to 1/4" in diameter and for grafting items like watermelon and cucumbers.
