Valiant Grape - how hardy?
I hope everyone is enjoying this great summer.
This spring I purchased a one-gallon potted valiant grape. When I planted it, it was "multi-branched" with a few two-foot long "branches" growing every which way. I trimmed it to two main branches, and would you know the plant just kept growing and growing. The tallest branch is growing straight up the trellis and about 7 feet high.
Anyways, I am just curious as to the hardiness of this plant. Is it "leave on the trellis" hardy or is it "lay on the ground and cover with snow" hardy? Or is it really just my personal preference? From what I read I don't think I need to mulch with leaves, peat, etc?
I am guessing that at worst during a bad winter the vine might not produce grapes the following year due to winter kill of the fruiting wood.
Anyways, the vine keeps wanting to growing through the trellis, from one side to another, but I have been purposely training the vine to grow on one side (not weave itself throw the trellis) just in case I decide to take it down in the fall.
By the way, it's funny how things work. I originally bought this plant to place on an arbour/gate and didn't really care if it actually produces grapes. Then I decided I wanted grapes so I planted it in a sunnier location, south side of a fence and carport. The metal arbour/gate did get a new plant, a clematis.
Thanks for any advice,
