Cannot afford a privacy fence but this neighbor has 6 aggressive dogs that terrorize my young children(and me!) while we are outside. I have a bucket and a half of Jerusalem artichoke tubers and access to free lilac bushes... how much would I regret lining the fence with sunchokes until the lilac bushes grow big enough? The dream is for the Lilacs to be a great privacy barrier but would take years to really be substantial.

Not sure this is the right sub but I figure if anyone knows about aggressive spreaders like sunchokes it'll be you folks.
