How Wide Should You Water?

After plants are established, most water absorbing roots are located near the dripline - which is beneath the outer edge of the plant's canopy - not too close to the trunk or stem. Concentrate your emitters along the dripline of each plant. The water will spead down and horizontally as it soaks into the soil, reaching the entire root zone.

To estimate how much water it takes to wet the root zones of your plants, see the chart.
