Four habits that protect tree roots
Water broadly
For established trees, spread water beneath the canopy and toward the outer root zone.
Go slowly
Use a low flow or multiple cycles so water soaks in rather than running off.
Protect the trunk
Do not keep the trunk or root flare constantly wet.
EVERY TREE IS DIFFERENT

A calculator cannot identify root disease, drainage problems, structural defects or species-specific needs.
Educational estimate only. Actual water needs vary by species, site, rooting volume, soil, drainage, slope, irrigation overlap, tree condition and recent weather.
