These are the two visits that make the rest of the year easier. Skip the fall one and you spend April dealing with matted leaves and snow mould.
Spring cleanup
Leaf and debris removal, bed cutback, first cut and edge, gravel raked back out of the turf, and a walk-around report on winter damage.
Fall cleanup
Leaf removal in two or three passes as the trees drop, perennial cutback, gutter clearing where accessible, and a final cut before dormancy.
