Rooted grapevine cutting: what to do until spring?
I took a cutting in late summer from a two year old grapevine and put it in a glass of water. It now has exactly four roots.
What do I do to encourage this cutting and keep it healthy until I can plant it in the ground next spring?

I would plant it in fresh potting soil and keep it inside on a sunny windowsill. Keep the soil very wet until you see some new growth then back off the water until you only water when dry(ish). Don't let it get bone dry. By spring you will have a sturdy plant ready for planting out. See this article about growing plants from cuttings.
