Crabgrass is an annual grassy weed that germinates in spring, grows lime green and large during summer, then towards the later fall, drops seeds. The following spring, the process starts all over again. This is why crabgrass is called an “annual” grassy weed. The good news is that crabgrass can be stopped very effectively using this product, which is formulated for use in DIY spreaders. It’s the same active ingredient the pros use. The best time to apply Prodiamine is in the spring or fall, as soil temperatures are between 55F to 70F. Each application of 3 lbs/1,000 sq ft provides about 3 months of pre-emergence protection.Our recommendation for both cool and warm-season lawns is 2 applications in spring if the target is crabgrass.For more details, you can check out the FREE Pre-Emergent Guide. If you download our FREE app it will tell you exactly when your soil temps cross these milestones. Application Information:DO NOT use Prodiamine if you are seeding or reseeding, as it will keep your seed from germinating.This product should be watered in within 48 hours of application for best results.
