Concord Grapes/when to plant

     When is the time to plant concord grapes and how long do they take
to produce an edible product?

 

I planted my Concord grapes last spring (March) and this year (2nd) we
had bunches the size of your hand.

 I would plant them this fall.  I do it before the first frost, but after the
extremely hot days.  I was told that doing it that way would allow the roots
to become established over winter.
