You could dig it up and add more soil. But grapes are just rooted cuttings so the part below ground is all rooted stem. I don't see where adding more soil on top would cause any issues. Those are tiny grapes clusters expanding. I'd cut them off this year. You can leave a few next year if it grows well this year. I'd cut it back to that bottom strong cane and tie it off to the stake for support. The young canes are prone to blowing out until they harden off. Wrap the brown part around the stake as well or tie it to the stake. Make loose ties so as not to strangle the shoots and remove the tie when it's no longer needed.

Don't worry about tall, plant it now. If it doesn't get tall enough chop off and start again next year -- you will still be ahead since the roots will be well established this year and it will take off vigorously next spring. Jolj is in SC where its sizzling hot in the summer. For that climate you don't want to plant now since it could fry the plant. For you it should be OK. Scott

I try to cut them down every year, but man do those things grow fast! And thick vines! Some are as thick as my wrist and grow so high up in the trees there's no way I can reach them. But...I'll find a place for the new ones and keep a good eye on them. Thanks. ;) V.
