South of Morristown the land settles toward the Great Swamp and the soil turns heavy — clay that holds water in April and bakes shut by August. Lawn Aeration And Restoration works with that ground instead of around it, opening compacted turf, feeding thin lawns, and giving roots somewhere to go before summer arrives. A tired lawn is usually no mystery; it is soil packed down by years of mowers, feet and freeze-thaw, and it answers to being loosened. Regular mowing, trimming and seasonal cleanups hold the gains once they have been made. There is a particular pleasure in walking a lawn in June that was bare and hard back in March.
