I am neutral on this comment because, I believe this particular vine is dead and did not produce any buds (yet) I will keep watching it and caring for it and hope it sparks back to life! Whiffletree has been a fantastic company to deal with. I highly recommend them!

Very good and no complaints or problems! All grapevine plants are growing well, delivered in reasonable timeframe as described. I would recommend anyone with similar interests, to buy here. I would also buy again in future, depending on stock availability and varieties.
