Suggestions And Ideas

Question

So dumb… (unrelated) I recently moved, the new house has unkempt grapevines… No clue how to make them happy and beautiful. Any suggestions from experienced owners would be greatly appreciated. Please no “search the web”, it’s why I’m here.

Answer 1

You're still good to prune hard—do it ASAP before they leaf out fully. Cut down to 2–3 thick main canes, about 2–3 feet (60–90 cm) tall. Trash everything else. Tie survivors to a fence or trellis—horizontal arms, 1–2 per side. Grapes only fruit on 1-year-old wood, so this reset gets them back on track. Mulch 3 inches (7.5 cm) deep to lock in warmth and moisture (straw, leaves, or bark chips). Water deep every 10 days after the ground fully thaws. Don’t fertilize until mid-May, then use low-nitrogen stuff or compost—too much nitrogen = all leaves, no grapes.
