Table 5-2 shows Landscape Dripline’s selection of flow rates, spacings and coil
lengths for a variety of conditions.
Use Table 5-3 to select the correct Landscape Dripline emitter flow rate and
emitter spacing for your base plant. First locate the soil type, then select the
emitter spacing and flow rate indicated in the right hand columns. Use 0.6 GPH
emitters for fine soils to avoid runoff and 0.9 GPH emitters in medium and
coarse soils for maximum coverage. Note your selection in the space provided
on the worksheet in Chapter 7.
Actual inline tubing spacing is then determined by the maximum width of the
planted area, evenly divided. See the Lateral Line Spacing Worksheet (Figure 5-2,
page 35) and Figure 5-3 for more information.
