[Growwine] Help to determine cause of Cab-Sev symptoms

[Glenda Baker]

Hi Anthony,

 

I think you should lime, if all nutrient levels are fine but pH is low then
the roots are not able to utilize the nutrients, nitrogen included. Foliar
sprays are fine but won't fix the problem long term. (Been there done that).

 

Agricultural lime here cost me $920 for 34 tons, have to apply spring and
fall and retest the pH levels, use a tractor with a lime spreader. Probably
cheaper for you where you live!

Hello All,
I need help in indentifying a problem I have with a section of my Cab-sev
vineyard.
 
The leaves are demonstrating a bizarre yellowing and redenning. The vines
are eight years old, and have produced normally for the last five. However,
now these vines have very small fruit clusters, the vines are not vigorous
at all and the leaves start to change color mid season.
 
We have run several soil samples and did come up with an unsually low pH of
between 4.5 to 5.0. All other nutrient levels seem to be within normal
parameters. I can send those along if required.
 
I have attached a few images at
