Unfortunately, rainfall is erratic and lengthy dry periods sometimes occur. During droughts some cities restrict the use of water for gardening. Because the trickle method of watering uses only a fraction of the amount of water required by sprinkler irrigation, the limited water supplies that may be available for the garden can be used most efficiently. The greatest advantage of trickle irrigation is its low water use. Fewer Weeds Germinate .
Water is directed only to the crop.
