Answer: Grapevines are vigorous growers but their root systems are not considered invasive. I have grapes growing within 3' of the foundation of my house and they climb up an attached deck and onto an overhead trellis. They provide wonderful summertime shade for my patio area, and I can pick the fruit with ease. They've been planted there for over 15 years and I haven't had a problem with their roots. Best wishes with your grapevines!
