Fill planters with potting mix. You'll need one pot per cutting.
Cut a grapevine branch into sections in early spring while the vine is still dormant. Each section should have three buds.
Cut one end of each section at a 45-degree angle. This side will be above ground.
Insert the cuttings into the soil with the two lower buds under ground.
Water the cuttings thoroughly and keep them moist all the time. Until they develop roots in about six weeks, they should stay in a warm place and away from direct sunlight.
Move your cuttings outside after they've rooted. Shield them from direct sunlight. The Oregon State University Extension Service recommends you wait one year before transplanting your new grapevines to a permanent site.
