Because shoots can grow 10 ft. or longer in a given year, shoot trimming is used to shorten the shoots. Shortening shoots can make management easier, especially spraying and dusting.

Depending on the crop size, shoots can usually be shortened to about 4 to 6 ft. long without sacrificing cluster or berry size. On trellised vines with shoots growing up and over foliage wires, shoots can be trimmed in early summer to about 3 to 4 ft. above ground.
