Homeowner guide
Small branches already on the ground may be reasonable to move if there are no wires, no tension, and no unstable overhead limbs. Large trees, leaning trunks, and roof-loaded limbs are different.
Storm-fallen trees can hold stored tension. A cut in the wrong place can cause a trunk or limb to roll, spring, or drop suddenly.
If the tree touched a structure, vehicle, fence, or utility-adjacent area, request help and send photos instead of experimenting with cuts.
