Half critical root zone
WebProtect roots: • Ideally, steps should be taken to protect the “critical root zones” of desirable trees. • The radius of the “critical root zone” is determined by multiplying the diameter of a tree in inches, by feet. In other words, a 10-inch diameter tree will have a 10-foot radius “critical root zone.” WebAug 7, 2024 · The critical root radius (CRR) is a figure used to determine a protected root zone based on the diameter (in inches) of a tree at four-and-a-half feet high. That number multiplied by one or one and a half feet will give you the CRR. Multiply the CRR by two, and that will give you the protected root zone (PRZ).
