<p>The invention relates to a device for supporting and training plants and in particular for layering tomato plants. It comprises a longitudinal stem portion formed with an integral hook which is adapted to grip and slide along a support wire which is mounted above and parallel to the plant row, and a spool rotatable about a cylindrical bearing surface of the stem portion. The spool carries a support cord which passes upwardly from the spool, through an aperture in the top of the stem portion and down through the hollow interior of the stem portion to where it is tied to the stem of the tomato plant. When it is desired to layer the plant the stem portion is moved along the wire and simultaneously the spool is rotated to pay out sufficient cord to layer the plant. Rotation of the spool is controlled by means of ribs on a flange of the spool which engage with the horizontal support wire.</p> |
