- Cover the area and seal the cut with grafting wax.
What happens to grape vines in the fall?
As temperatures fall, vines gradually become more cold hardy, and sugars are converted to starch to be stored for the winter, mostly in perennial structures such as roots and trunks. After leaf fall, vines continue to acclimate to cold weather, but no more carbohydrate accumulation occurs.

How do I grow bigger grapes?
Give grapes a chance to grow larger and to get more plant nutrients and water per grape by shortening the cluster. Take off the bottom half of the cluster, leaving four to five side branches near the top. Since these branches grow sideways from the cluster’s main stem, they have room to hold fruit without crowding.
How fast do grape vines grow in a year?
