Grape cutting propagation is mostly carried out in spring. Under high temperatures in summer and autumn, it is generally difficult to propagate grapes by cutting. I have conducted experiments with various treatments and summarized a method, which is described as follows:
I. Selection of branches: Choose grape branches with buds that have just started to germinate. After cutting, remove the leaves, and cut the cutting branches to a length of about 15 centimeters, ensuring that each contains at least one bud that has just started to germinate.
II. Method of cutting: Use clean fine river sand as the seedbed. Insert the cut grape branches into the sandbed at an angle of about 45 degrees to the surface, ensuring that one bud that has just started to germinate is shallowly buried about 1 centimeter below the surface of the sandbed, and no bud is exposed above the sand. After cutting, keep the sandbed moist and avoid direct sunlight.
III. Changes in the cutting branches: About 10 days after cutting, the germinating buds emerge from the surface of the sandbed and turn green. About 20 days after cutting, the bud that is growing has formed adventitious roots. About 35 days after cutting, the growing bud has 2-3 leaves unfolded, and the node where it is located has formed a large number of young roots, which means the cutting has succeeded.
The survival rate of this method is generally around 80%. The key to this method is to shallowly bury the just-germinated bud in moist fine sand. Because if the just-germinated bud is exposed on the surface of the sandbed, the bud will germinate and grow too fast, and it will not be able to induce root formation and growth in time, eventually drying out and withering; if buried too deep, the bud can germinate and grow, and roots can form, but the bud will have difficulty breaking through the sandbed surface and will not survive. Only by shallowly burying the just-germinated bud about 1 centimeter below the moist sand surface, allowing the bud to slowly emerge from the sand surface, and timely inducing new roots, can the absorption and loss of water reach a balanced state, and the plant will survive.
