The soil around Arey's Pond in South Orleans is glacial outwash — sand, more sand, and whatever generosity anyone has managed to work into it. Terra Firma Permagardens tends the green that grows on top: lawns mown and edged, garden beds kept, cleanups carried out so nothing smothers what's underneath. Late August is the test, when the heat has been long and the water table low and only a well-tended yard still looks willing. Working with Cape ground means patience and repetition, and the payoff is a property that holds its color into the shoulder season. It is slow, particular work, and it makes a place feel rooted.
