There is some truth to the adage that grapes like poor soil, as too rich a soil generally causes poorer quality fruit as well as problems for the vines’ hardening off in the fall, leading to greater winter damage. Grapes should also not be planted where water stands after a rain, as they do not tolerate wet conditions.

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.
