A few leaves on my Aglianico back-up vines look a little weird.
I am not worried about them. But I wanted to put it to readers: should I be? What are the changes in the photos below?
In medicine, we call this a “differential diagnosis”: a list of possible causes of a symptom or phenomenon. As one grows wine grapes, it’s good to keep an eye on what’s happening with the plants and to know what could cause some changes or unusual appearance of the plant.
It may be fun to test our common knowledge….
