Schedule: Deep, infrequent — typically every 10–21 days mature, more often in summer establishment.
Emitters: Multiple large emitters or bubblers placed out at the drip line, not at the trunk.
Encourages deep roots and long-term tree stability. AE designs irrigation to expand as the tree matures.
Arizona yards have very different microclimates. West-facing walls, glass, artificial turf, pavers, travertine, porcelain, and pool decking all increase reflected heat. AE considers these before confirming placement.
