Grapevine propagation should take place in the late winter and early spring months. You should select hardy and prosperous hardwood to propagate from. The wood you select should be healthy and should have ripened the summer before. Propagated vines grow easily if you follow some simple steps.
Cut stems with three to four buds between 23 and 30 cm (9 and 12 inches) in length. Your cut should slope and be above and below the top and bottom buds.
Dig a v-shaped trench where you will plant your stems. Make sure your trench is big enough for the amount of stems you have cut and that it has a back wall.
Fill the bottom of the trench with sharp sand. You will need to fill it at least 8 to 10 cm (3 to 4 inches) high.
Wet your cuttings and dip them into rooting powder.
Place each cutting into the trench against the wall with the bottom end of your cutting in the sand. The cuttings should be at least 10 cm (4 inches) apart.
Fill the trench slowly, leaving just about an inch of the bud exposed above ground.
Plant your cuttings in a permanent location the following winter.
