Lee Gilliam brings in arborist Brandon Maltby to diagnose a red pine that has been browning out for years, and the treatment starts with mulch, fabric, and dead needles before any spray schedule. Nathan Gilbert then walks a first-time Detroit homeowner through a top-to-bottom maintenance checklist, from shingles and gutters to the water shutoff, the gas meter, and a house binder.
