i think i poisoned my grapes!

[padolin]

I thought it would be a good idea to maybe put some fertilizer around the bottom of all my grape vines. Last Sunday it finally rained. 3 days later I go out to the vineyard ( and brave the mesquitos) and my Ives grapes have this rust colored thing on the edge of the leaves. it almost looks as if they were burned. Im gonna guess its from over fertilization.

How much of what did you use?

 

[padolin]

I used a generic 5-10-10 fertilizer. Maybe 1/4 cup sprinkled around the base of the vine.

How close around the base? If you were out 18" or more, 2 oz is not that much. And the first number, 5, is the nitrogen. 5 is not very strong. I burn mine with 13-13-13.

 

[grapeman]

That amount should not burn the vine unless you got it right on the vine.

 

[padolin]

yeah, i think it was right at the vine. it may have come in contact with the vine. Could it be something else?

 

[garymc]

Well, it could be, but in the future, think of it this way. Make them go and get the fertilizer. If your vine's roots are 3 feet long, put the fertilizer 3 and a half feet from it and the roots will get what they need.
