Abstract: A fastener and method of securing a plant to a wire is described. The fastener may be used, for example, to secure a grapevine to a foliage wire. In one embodiment, a flexible fastener is provided that can secure the plant. The fastener includes two convex portions for attaching to the wire, and can deform to restrain the plant against the wire. In one embodiment, the fastener is deformable to allow the two convex portions to overlap and accept the wire, thus restraining a plant. In another embodiment, a biodegradable fastener is provided that can easily secure a plant to a wire, and which can be left in the field to decompose.
