Walnut Brook runs low and clear through Flemington in September, and the lawns above it hold their color right up to the first hard frost. Carrega Properties LLC keeps that whole arc — mowing, trimming and cleanups while the grass still grows, then plowing and salting the same driveways once the ground goes iron-hard. Looking after a property across the turning year means knowing where the water sits in April and where the wind stacks drifts in January. The reward is small and specific: a clean line along a walk in July, a drive open to the road before the mail comes in February. Hunterdon asks for both kinds of work, and both are worth doing well.
