PGR reapplication tracking

Plant growth regulator timing uses a Celsius-scale accumulation, not the seasonal Fahrenheit one. This page tracks a 10°C base, which is the Bermuda (warm-season) figure. Trinexapac-ethyl is typically re-sprayed near 200 GDD on cool-season turf and roughly 216 to 230 on warm-season turf, measured from your last application rather than from January. Always follow the product label.
