Direct-to-root delivery

Water, air and nutrients reach the active root zone – catalog-stated design purpose.

Downward root growth

Encourages deep rooting instead of surface roots – better drought survival.

Zero runoff

Below-grade distribution loses nothing to evaporation or slope.

Filter basket

Perforated strainer keeps coarse media out of the tube.

One per root ball for young trees; two or more positioned around the drip line for mature specimens.
