I was hoping you'd suggest a model under US$100, and you did! You answered all my questions. Blessings, Suzana Rockhold St. Mark's Centennial Vineyard Lomita, CA Danie,

I pruned mine in February and moved (transplanted) mine in early April and they are thriving. I don't know if it is good to (move) them in the fall but I will try. Again, I am not Danny, but your vines probably won't produce until their "second year" as mine did. Another thing when pruning Bill: When you prune in early spring make sure to cut only that part of the vine which is "pencil thickness" to about 10 inches. Shove this in the ground three inches and you will get a young vine that takes three years to produce. I did this with 80 cuttings in various parts of my yard and 15 started growing using this technique. You could also put these cuttings in water and they will start to sprout roots which can be put in a pot to grow until it is time to put them in the ground. I just started three years ago and the experiments continue, my crop is looking divine for just 3 years of loving care. My name isn’t Danny but I have a ‘partial answer’ to your question.

They did not 'rebound" but the pruned vines are doing extremely well (at least in my yard). That's Mother Nature for you, always "throwing a curve at you". Just a little reminder that we can't always rely on any crops to produce under these conditions. One more thing, there are these 'beatles' with a shiny blackish green shell which are feasting on my young vines/leaves. I grab a jar and slowly, yet quickly push them in the jar with my fingertips (they won't move if you 'sneak' up on them) where they will die a slow death. Anyone else out there see these bugs, that's it for today? Happy vining everyone!

Also, the measurment os a single berry does not represent the sugar content of the grapes on a vine, and is meaningless. for a single vine, take a plastic glass of about 200 ml and put at least 20 berries. for a real vineyard take about five berries from each 6-7 vines up to about 200 ml. crush the berries with a clean plastic rod or a clean wooden piece. draw a little amount of the juice and put it on the glass without toucung the glass, and read the sugar concentration. sincerely Aharon Yerushalmi Dear Danie

I can not avoid my comment on your instructions of use of a refractometer
Never put any solid material on the glass of the refractometer.
any scratch will destroy the accuracy of measurment and the refractometer.
Also, the measurment os a single berry does not represent the sugar content of the grapes on a vine, and is meaningless.
for a single vine, take a plastic glass of about 200 ml and put at least 20 berries.
for a real vineyard take about five berries from each 6-7 vines up to about 200 ml.
crush the berries with a clean plastic rod or a clean wooden piece.
draw a little amount of the juice and put it on the glass without toucung the glass, and read the sugar concentration.
