Hi, I'm Daniel Penselin, and this is how to care for grapevines. The things you will need: grapevines, garden shears and a hose. You will want to keep your grapevines neat and tight by clipping and removing dead or diseased vines. Try to check this weekly using garden shears to cut off the damaged vines, cut them back to the main vine. Also, you want to make sure that the vines get watered daily and that they get a nice mix of sun light and moisture. Finally, you'll want to make sure and keep the vines organized by removing any intertwining vines allowing the stronger vines to grow freely. And that is how to care for grapevines.
