Product Description:
Most DIYers use this Prodiamine in the spring to stop crabgrass. 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” grass 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. This will give you approximately 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.
Application Information:
DO NOT use Prodiamine if you are seeding or reseeding as it will keep your seed from germinating.
This product MUST BE watered in within 48 hours of application for best results. See the following table for the application rates we recommend.
