What's wrong with my grape vine?

oohstella(6a)July 10, 2014

Our grape vine is doing well this year � it has spread out all over our back wall, and has been producing many green grape babies.

Still, a few of its leaves are yellowed, while most of the green leaves are covered in black dots. We have been watering it every day and it is in a spot with a lot of sun. Do you think it is sick? If so, what can we do to save it?

Here is another photo of the entire vine.

It's not sick. It's lacking nutrients. Get an all around fertilizer and give it some love. It needs potassium, nitrogen, and a ton of other stuff. Do NOT give it lawn fertilizer! Give it something for fruit bearing trees.

Your grape vine may also have a touch of leaf spot fungus too. In your first photo I noticed spots on both leaves, so it's a possibility. I'm including a link to a resource concerning that fungus.

Here is a link that might be useful: Leaf Spot of Grape

Is it growing in a container? If not, why the daily water? I have not watered any of my vines in years since they were babies getting established.

goodground, I was thinking the same thing. Desertdance is in Z9 California though...they don't have the soil moisture we do. "It never rains in California, but girl don't they warn ya'........"
Still...I agree with you. I wouldn't think daily water should be necessary.
