Answer: Both those varieties are hardy grapes, and since the vines are growing well I don't think that's the problem. Also, often vines won't bear a crop for the third or fourth year, so your vines may be on track. You didn't mention if you fertilized, which will promote flower and fruit set. After growth starts in the spring, spread about one cup of 10-10-10 around each vine about one foot to two feet away from the trunk. Water well before and after applying to prevent burn. Hope this info helps!
