Wet Spots in Your Garden
The wet spot on the surface of the soil is misleading. The wet spots are at certain intervals, but don't represent what is going on. The photo on the left shows the misleading wet spots. The drawing on the right (from my book Drip Irrigation of Every Landscape and All Climates) shows that the wet spots beneath each emitter merge to form one continous zone of moisture. The soil for the entire length of the in-line tubing is moist some four to six inches beneath the surface, depending on the soil type. Sandier soils require tubing with the emitters pre-installed 12 inches apart. While heavier, clayey soils only need emitters every 24 inches.
