Wondering if you’re too late to apply Prodiamine pre-emergent to your lawn? Don’t worry! If your soil temperatures are still between 50°F and 70°F, you can go ahead and apply Prodiamine, whether you prefer granular or liquid application. Crabgrass typically germinates within this temperature range, but not all seeds sprout at the same time. Applying Prodiamine late is still effective and offers valuable protection against weeds. In lawn care, it’s truly “better late than never.”
However, if your soil temperatures have already climbed above 70°F, it’s best to skip the Prodiamine for now and plan to include it in your fall lawn care strategy.
Fall Application Window for Prodiamine
In the fall, the ideal window for applying Prodiamine is when soil temperatures drop from 70°F down to 55°F. If you miss this fall window, don’t stress—colder winter temperatures will help suppress weed growth naturally until the next season.
By timing your Prodiamine applications based on soil temperature, you’ll maximize weed prevention and keep your lawn healthy year-round.
