Jonathan Green Veri-Green 16001 Crabgrass Preventer Plus Lawn Fertilizer, 50 lb, Bag, Granular, 20-0-3 N-P-K Ratio

Jonathan Green Veri-Green crabgrass preventer plus lawn fertilizer feeds and greens up the lawn for up to three full months and provides pre-emergent control of crabgrass. When applied prior to germination it controls other weeds such as goosegrass, dallisgrass, chickweed, henbit and oxalis. This product contains an advanced herbicide known as Dimension® that unlike other Crabgrass controls provides post-emergent control, meaning it will kill weeds after they have germinated. Postemergence control is limited to crabgrass and is effective for up to 4 weeks post-germination. It will only kill the plant up to the 3-leaf stage of growth; a fully mature crabgrass plant has seven leaves.
