Most people call after one of four things. A storm came through and left limbs across the yard. They spent a weekend pruning and now there's a pile bigger than they expected. They're getting a property ready to list or rent. Or the municipal brush pickup wouldn't take it — most towns cap branch diameter and length, run pickup on a narrow schedule, and won't touch anything stacked wrong. There's no season for this one. Storm debris in particular is worth clearing quickly, since a wet brush pile sitting on a lawn kills the grass under it in about two weeks and attracts everything you don't want nesting near the house.
