By the first dry week of March the big oaks on Englewood's West Side are still bare, and the lawns beneath them are carrying everything winter left behind. Rmm Tree Service Corp. opens its year right there — spring cleanups, matted debris pulled off the turf, beds edged back, and the first cut once the grass will take one. Lawns wake unevenly in this town, sun side first and shade side weeks later, and the skill is knowing which is which. Handle March properly and the yard is full by Memorial Day instead of thin by July. It is a long game, and it begins in the cold.
