May in Henry Law Park is loud with kids and high water, and every lawn in the city is climbing at once. O'Brien Landscaping meets that surge with the mowing and trimming that simply has to happen weekly for a while, plus the spring cleanup that clears the way for it. The Washington Street side of town has uneven old ground and mature trees, which makes for shade lawns, slow corners and plenty of hand work. Autumn brings the reverse errand, hauling off everything those same trees drop. There is a quiet good in handing a yard back ready for a Saturday.
