0-0-7 Prodiamine Granular Pre-Emergent Herbicide
Yard Mastery 0-0-7 Prodiamine is a granular pre-emergent designed to stop weeds in the lawn, such as crabgrass, poa annua, bittercress, chickweed, and henbit. It’s the same active ingredient the pros use, formulated for easy DIY application.
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, and then, towards late 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 effectively using this product. The best time to apply Prodiamine is in the spring or fall, as soil temperatures are between 55°F to 70°F. This will give you approximately 3 months of pre-emergence protection.
