En el césped, el momento gana al esfuerzo
El año entero de su césped, planificado en diez segundos.
Dos preguntas. A cambio: su ventana de preemergente, el calendario de fertilización, las fechas de siembra, las amenazas que vigilar y las normas locales que le aplican — todo construido con datos agronómicos reales de su estado.
Sin registro. No hace falta correo para ver su calendario.
Application windows
Pre-emergent, weed spray, feeding and seeding — timed to your region's soil temperatures.
Season by season
Four task lists filtered to your grass type, so you never read instructions for someone else's lawn.
Amenazas que vigilar
The diseases, weeds and pests actually documented in your state.
Local rules
Fertilizer blackouts and restrictions that apply where you live.
Las tareas y las fechas de abajo se muestran en inglés a propósito: son cadenas publicadas por los programas de extensión de cada estado y las reproducimos tal cual. Preferimos dejar una fecha citable intacta antes que traducirla y arriesgar que se desplace.
Why lawn care is mostly a timing problem
Almost every expensive lawn mistake is a timing mistake rather than a product mistake. Pre-emergent applied two weeks late does nothing at all, because the seeds it was meant to stop have already germinated. Nitrogen applied to a cool-season lawn in July feeds fungus more than it feeds grass. Seed sown in May in the North dies in the first heat wave. The bag on the shelf is rarely the problem; the week you opened it usually is.
Worse, the correct week is not the same for everyone. Soil temperature drives germination, and it crosses the critical thresholds weeks apart between the Gulf Coast and the Great Lakes. Grass species matters just as much: fescue is fed in autumn and left alone in summer, while Bermuda wants the opposite. Generic monthly checklists fail because they average all of that away.
Qué hace este calendario
It combines your state's documented conditions — USDA zones, soil profile, humidity, frost dates, application windows and local fertilizer regulations — with the requirements of your specific grass type, then filters the task list so you only see instructions that apply to your lawn. Tasks naming a different species are removed rather than left for you to sort through.
Tome las ventanas como rangos, no como citas
Every window here is expressed against a biological trigger, usually soil temperature, because that is what the plant responds to. A window that reads "early March when soil temperatures approach 55°F" may arrive in late February one year and late March the next. Watch the trigger, not the date.
Las guías detrás del calendario
Each window this tool prints has a full guide behind it. Spring turns on pre-emergent timing; summer is mostly watering discipline and knowing whether a brown lawn is dead or dormant. Fall is the season most lawns are actually won or lost: fall lawn care, the overseeding window, the winterizer feeding timed to the last mow, and mowing the leaves in instead of raking them. And if fall gets away from you, dormant seeding is the deliberate late window that beats waiting for spring. Every season also exists as a printable one-page checklist: spring, summer, fall and winter.
