    Im in ohio and we've had tons of rain. Any clue why my vines look so bad? Leaves are curled and many dying/dead, some grape starts are same.

    I sprayed fungicide a few times and bug spray, also put down fertilizer. Not sure what to do to help. 20190521_173425.jpeg 20190521_173413.jpeg

    Dude, you should prune all the weeds and competitive growth around the vines. Seriously...

    You need to take a leaf sample to your county ag. agent they should be able to help.

    I've had sluggish growth on quite a few vines this year too. I blame it on the lack of sun and warmth. It's been in the fortys more than it's been in the sixtys, with incessant rain, so the vines are waiting on some heat! We had two days a week ago that it got in the eightys, and I saw an immediate response!

    Hopefully the next few weeks grow some new good looking leaves to soak up the sun.

    I had some that started out slow and ugly but they’ve really picked up this past week since we’ve actually had some sun and heat. I’m not too far away in Pennsylvania.

    What fungicide did you use? What variety? This has been a bad start for us growers in Ohio. Too cool and too wet. My newer vines have struggled but the older (4+) vines seem to be moving along. It looks as if I will lose a couple of 3 year vines due to the weather. Another thing I suggest is to get a leaf analysis done so that you can tell how your plants are doing. There is a place near Washing CH (Spectrum Analytic) that is cost effective and has an agronomist on staff that is very knowledgeable in viticulture. I do samples every year to guide me on which supplements to add in late winter. For me, if a vine is struggling, I first pinch off all inflorescence I see and fall back on making the vine hardy again (roots and leaves).

    I wonder what variety the grow around London, UK? It was 67 and foggy here this morning. The humidity is very high (duh). Perfect for growing fungus.

    That looks like herbicide damage to me. Has anyone sprayed anything near the plants? Any "Weed and feed" added to your lawn? Any neighbors spraying products in their yards? Was your sprayer previously used for herbicides and maybe contaminated?

    I agree with Greg. Upward cupping of young leaves is a sign of dicamba damage.

    I'd prune off the low shoots. I would have rubbed them off as soon as the buds opened on the trunk. I like my trunk to be bare. If your vine is going to absorb a weedkiller, the leaves near the ground will be the ones to get it.
