    Abstract: A plant grafting system comprises a cutter assembly. The cutter assembly has a pair of V-shaped upper razors and a pair of V-shaped lower razors. A holder/insertion assembly is provided. The holder/insertion assembly is laterally spaced from the cutter assembly. The holder/insertion assembly has blocks and clamps for retaining the lower portion of an upper plant and the upper portion of a lower plant with respect to the razors. Next provided is a first drive to move the cutter assembly and razors for cutting a V-shaped recess in the upper portion of the lower plant and a V-shaped projection in the lower portion of the upper plant.
