does anyone have ideas on what is wrong with this plant.

One person thought weed killer may have done this,I don't think I would have a good vine flanked by two bad ones if it was weed killer. I have a sprayer that I never use weed killer in, and use it when spraying ferts and insecticide.

Is it the vines that are buried that are only doing this?

I agree with the herbicide...but I think it is in your soil..bad compost?

I only have a few vines that are not buried, about half of those are ok. The only type of weed killer I have used in this patch would be a contact killer like round-up or its generic equivalent.

I did use a well composted horse manure, but in two patches, the other patch is fine. The manure came from a farm that raises expensive show horses, I don't think they would use any herbicides , but I can ask them.

The bad looking leaves are also the darkest green ones on the plant.

I have had a few leaves that look like that and no herbicide was used or anything brought in that may have had herbicide used on it. The first ones I saw like that were the first few leaves on the plant. People said sometimes the first ones are funky. But the plants were ok after that. Now I have some looking like that, that were growing under other leaves. (one plant growing into the territory of another plant.) But yours don't fit either of those categories, so I'll be interested to see what people say. Good luck with your plant, I hope it is ok!

OK then we are going with severe nutrient defeciency...Have you had a soil test?

It looks like herbicide damage, this could be caused by a long term herbicide. The herbicide could have been in the horse feed hay and grain. Last year in Vermont there was a composting facility using hose manure which did have a herbicide problem.

Herbicide damage.
I have to say Bait, the soil looks a tad dry. Keep it moist.

Take some of the soil and try germinating radish seeds in it...that will tell you if it is a herbicide

I am off to work, I did ask the guy I got the manure from if any weed killers where used near him ,and He said absolutely not,and their are no fields near him,I have beans near me, only 4 feet from the plants stump, but I dont think they spray beans.

I do believe those saying its a herbicide, Ill try the radish seed method .

got to go

birth defect? genetic? Compacted clay soil causing nutrient deficiency? Tissue test.
