Within weeks. A cleanup and disposal job rather than a tree-health event — with one caveat that matters. Debris on the ground means limbs left a canopy, so the real question the pile raises is what else is still hung up in those trees, and whether any of it is lying across a service drop hidden in the brush.
Weeks, with genuinely low risk while it sits — a brush pile on the ground is stable and is not going to hurt anyone. What degrades is not safety but your options and price: after a widespread storm, reputable crews book out for weeks and municipal brush-collection windows close, so the same job gets slower and more expensive a month later. The one thing to check before touching anything is whether a service drop is lying under the pile.
