These ingenious clips are the perfect size and shape for attaching stems of delicate plants to plant supports or trellises. Great for tomatoes and roses, and for indoor plants like orchids. Ultimate plant clips are completely reusable. The curve in the center goes around the stem of the plant, and the two hooks can attach it to a vertical string, wire, or trellis. These are very useful for training orchid stems, but also handy in the greenhouse for holding up vine tomatoes, cucumbers, and any crop that needs to be trained in order to save precious garden space.
