Spray Day: Lawn Weed Timing

Should you spray right now? Spray Day turns live weather into one clear answer - SPRAY, WAIT, or DON'T - for your specific lawn or garden product, based on its rainfast, wind, and temperature limits. Every weed killer, fungicide, and insecticide has its own rules: how long it needs to stay rain-free after you spray, how much wind causes drift onto a neighbor's plants, and the temperature range where it actually works instead of burning the grass. Cross-checking all of that against an hourly forecast, every time, for each product, is nobody's routine. HOW IT WORKS 1. Add your product: pick its type (weed killer, fungicide, insecticide, and more) or set your own rainfast, wind, and temperature limits. 2. Spray Day pulls the live hourly forecast for your location. 3. You get a single verdict - SPRAY, WAIT, or DON'T - with the reason and the confidence for right now. It takes 20 seconds to set up. No account required. CORE FEATURES Today's Verdict A single answer plus the why - next rain, wind with gusts, temperature, and inversion risk, read at a glance instead of pieced together from a weather app. Why This Answer Every verdict lists its reasons in plain language, like rain arriving before the product is rainfast, or wind above the drift limit.
