How is the watermelon cleft grafting method done? A detailed explanation of the key grafting techniques

(Agricultural Wealth Network) For the cleft grafting method, the rootstock should be sown 7 to 10 days earlier than the scion; the suitable timing is when the rootstock has 1 true leaf and the scion's cotyledons have unfolded. When grafting, first remove the rootstock's growing point, use a blade to split downward from one side between the cotyledons to make a cut 1 to 1.5 cm long, then take the scion and make one cut on each side of the hypocotyl below the cotyledons, with the cut surface 1 to 1.5 cm long, forming a wedge shape. Insert the prepared scion into the rootstock's split opening, then tie it or clip it with a grafting clip.
