irrigation in vineyards provides excellent water management, allows
better fruit production and reduces problems of unwanted mold growth.
It is well suited to the slopes that are favored by grape growers. These
slopes present problems of erosion and runoff when any other irrigation
method is used. Even the largest and most traditional wine grape growers
have converted to drip irrigation.
The preferred method of installation is to tie poly tubing to a trellis
wire which is suspended about 18 inches above the ground. The wire is
attached to the grape stakes. At this height, the tubing is above the
area where ground work, such as weeding, is done. Once tied on, the
tubing should be allowed to unwind for a few hours so that when the
emitters are punched into the bottom surface of the tubing, they stay
pointed down. This way, the drip falls where intended, instead of running
along the tubing. Since vineyard rows are often long and on uneven terrain,
pressure compensating emitters should be considered.
