Grape Growing Zones

Can you wait for the seeds were planted too late?
I tried to daisy plant tomato seeds and thinking that wouldnt Shasta grow grapes, but they did. If you plant in the ground, will come next year or habit strong enough roots for the winter? How do I with these plants? (I'm in zone 6) become mature plants, so I brought inside and spring planted later? Thanks for the tips that I can give! I live in Pennsylvania. The plants will not mature and produce flowers or fruit this year. They are very small plants … we have only 2 fair and warmer months.
I do not know what is zone 6, but as long as they keep about 55 degrees farenhiet should spend the winter. Do not water the roots even deeper if you have the space wetif free in a glass house that they put there you have nothing to lose, and will flower in early
