I transplanted a Concord grape vine last fall, like early November. By the end of May (5/31), the plant was still dormant. So I decided to dig it out. Then I saw some white hair (roots) in the soil. So I put the soil back.
Then two days later (6/2), I saw some buds coming out. I guess I waked up the giant. Here is a picture taken on 6/19.
It takes that long for a good trunk, then you won’t be able to stop the thing! Mine seems to grow feet within days. Birds and coons love mine though, so I get very few. I’ve bagged them and netted to no avail. You will have cordons galore within the next two years.
