I finally finished my first round of stuffing shoots. It is a task akin to painting the Forth Bridge. Just when I think I have crammed the last wayward shoot into the trellising wires I have to return to the vines where I started and begin the process all over again until they are big enough to behave themselves. Teenagers!!!I did however manage to set some time aside to perform another important spring operation in the vineyard: gathering petiole samples for analysis of nutrient content in the plant tissue. Analysing the presence of absorbed nutrients is a good way to see how healthy your vineyard really is. Or not.
There is conflicting opinion as to whether the leaf blade is a better indicator of nutrient content versus the petiole. UC Davis has advocated for years that the testing of petiole samples is the most accurate measurement of the vines uptake of nutrients. Now there is a school of thought that believes that testing the blade is a more accurate indicator. It actually makes sense to me, after all, the petiole is merely a channel by which the nutrients are delivered to the business end of the vine. The leaf is a little food factory which, when aided by sunlight, converts the nutrients deposited there into something the winemaker can use: all that sugary goodness that eventually becomes alcohol.
Having said that, I dutifully performed my petiole sampling of the Cabernet sauvignon and Syrah vines and sent the tissue to Dellavalle Laboratory Inc. Maybe next time I will try a blade sample.
Now I just have to wait for the results to see what my poor little vines are craving in the way of nutrients.

The mind boggles...I have found that a good pan of scouse provides all essential nutriments.
But maybe an analysis of your deficiencies, and an adjustment for such, would help with your spelling!

Thank you!
my little vine arrived recently ony to find her in a poor state. only time will tell if she picks up hopefully the sun will come out agian to give her a little nudge in the right direction.
Aw...what's wrong with the poor baby?
Good grief--What with poles rising from their crypts and now powdery mildew disovered I've forgetten to send in my petiole anaylsis. Seriously, PM found on some clusters and extreme action called for. How much wettable sulphur to add per gallon of water? And, once a bit of mildew has taken hold, can the grapes be saved? It was playing golf that destroyed me this weekend when I thought things were under control, but I did call Godfather Jack to wish him well June 6th. He did not land at Normandy; he was fighting on the Italian front years before. He tells the story of finding Michelangelo's David in hiding after liberating Rome....In honor of Jack, and all the veterans, we can simply do the best we can in the moral equivalent of war. Be the best at what we do (whether that be as grape grower, a student, or a simple carpenter) and never give up. Thanks in advance about the PM
Hear Hear Mr Justice!
