I just received concord grape seeds in a trade. I'd like to give them a go but don't really know where to start. Would winter-sowing work?
Hints, tips and suggestions would be appreciated.
A Z4 winter will give them more cold than they need but you could try winter sowing them. Approx 2-3 months at 35-40F before bringing back to about 70F should help in germination. But the fruit from any vines resulting could be variable and not have all the characteristics of the grapes the seeds were taken from.
