On a June evening the Normans Kill runs cool through Tawasentha Park and the whole town smells like cut grass until dark. Rogotzke Landscaping works those hours — mowing, running the edge along the walks, trimming wherever the mower cannot reach — across Guilderland's neighborhoods and its longer country lots alike. Spring and fall cleanups open and close the year on either side of the mowing. A lawn does not need to be complicated to be lovely; it needs to be level, edged, and looked after on a rhythm. Keeping that rhythm is the craft of it.
