Over Winterin Mature Grape Plants

Question

i read the over wintering article. says to lay your plants down and cover in ditches. Is that necessary in zone 5b? And how can you lay down mature grape vines because they are so thick and not flexible near the bottoms

Answer 1

If your vines are hardy to zone 5 they should be able to overwinter just fine without a lot of cover. You could try the simpler method of mounding soil up around the base of the vines, rather than trying to lay them down.
