These Plant Support Yo-Yo’s are perfect for supporting heavy fruiting crops such as tomatoes and cucumbers during their final stages of growth. Simply attach the support to a ceiling or hanger and attach the support hook to your plant. As the plants grow the self tightening mechanism will support and tighten without restricting growth, removing the need for regular re-adjustments. The Yo-Yo’s also have a lock function which will stop any movement at all once they are setup. A true essential for the keen gardener.
