Gardening, lawns, plants and home improvement — the sites people check before doing something outdoors.

PlantDates is a set of free garden calculators that work out when to sow, start seeds and transplant for a given US ZIP code. Every frost date is the median of thirty years of 1991–2020 climate normals, and the site is careful to say each one is a probability rather than a promise.
LawnDates is a set of free lawn-care timing tools for US homeowners: when to overseed, aerate, fertilize and put down pre-emergent in a given ZIP. Every window is an offset from the median frost date at a real NOAA station, and each city page names that station and its distance.
