Grapes, dormancy and green leaves wilting at hard freeze
I established three 2-yr grape vvines this year. This will be my first
winter. I have some concerns... One of them had a green supple leaves until we had a hard freeze two days ago. One had fall-colored leaves like any tree, and the third had shed its leaves already. My concern is the green-leafed one. All the supple green leaves are now wilted and limp (we are sustaining cold under 30 degrees throughout the night day). Does this hurt the plant? I'm thinking it got too much water at its location and didn't shut down properly for winter. NExt up is the location I placed two of them is not good. The sun and support is great, but the water isn't. The overhang of the house is too much and everything on that strip is not getting enough water from nature. How should I handle this for winter? I'm thinking I should handle it as if I'm overwintering it indoors. Maybe water them once a month?

A killing frost will make the leaves wilt and kill them. This is normal. Look at the canes. were they tan or brown before the freeze or green. If they were brown, then they probably have already hardened off and the cold did not nor will it hurt the vine. If they were green and now are sort of soft and mushy, then they are probably dead. |

Thanks. Most of the canes were already a dark reddish brown and hard. Towards the growing tips were the only green stems. They aren't mushy but if the tips die i'm not too worried. I let them grow too long anyway. DiGiTAL ViNYL (no email) Zone 6b/7, Westchester Co, NY, 1 mile off L.I.Sound 2nd year gardener http://photos.yahoo.com/ph/royalfrazier/ |

If you are unsure how to properly prune, I suggest you get the inexpensive book titled "From Vines to Wine" by Jeff Cox. You might even be able to pick up a used copy at amazon.com It is one of the best books I have found on growing, training and pruning grapes with lots of line drawings illustrating the concepts. |

I'm still unsure. From reading about, fruit is only produced on shoots growing from one-year-old canes. This was the first year planted (although they were supposedly two year roots). The way they are now they have curved over eachother in a bow forming an archway against the side of the house and railings. (They arch over a stone alcove). I need to build trellis or something else to better hold weight from grapes for next year. http://pg.photos.yahoo.com/ph/royalf...27.jpg&.src=ph One run on the right from the grapes grabbed a hold of a nearby tomato plant and wound its way up to the top of the porch (12-15ft high). It latched onto all the support strings as well as the tomato vine. I've since taken the tomato down but I'm not sure about that grape vine. I've heard that the longer the vine the smaller the grapes? True? I do have BOUNTIFUL CONTAINER GARDENING which has been an excellent book and covers grapes. I'll look for the Jeff Cox book although I'm not interested in winemaking at all. I can't drink the stuff.

The other part pertains to planning, planting, trellising and pruning. Unless you prune properly, you will have a MESS next year and it will keep getting worse in subsequent years |
