Cuttings from a grape vine

When all the leaves fall off the vines and the plant is dormant, cut a half dozen pencil sized cuttings that have at least three buds. Cut the bottom end of the cuttings on a slant about 1/4 inch below a bud and dip them in rooting powder. Completely bury them upside down in a coffee can, with a lid, filled with potting mix. Upside down will cause the growth hormones to go upwards to the the area where you want roots to form. Water them lightly, put the cover on and place them in a cool spot until Spring (you might peek every once in a while to make sure the mix is still damp). Layering now or potting up now may not work because the plants are not in a growth cycle---that's what Spring is for. Around the end of February take a look and you'll probably find lots of roots and even some shoots starting----that's when you will pot them up.
