This Hi-Yield granular preemergent stops crabgrass and a long list of annual grassy and broadleaf weeds before they ever sprout. Its useful trick is a wider window: it can go down up to four weeks later than most crabgrass preventers, handy when spring gets away from you.

Use it on established lawns and in ornamental landscape beds around trees and shrubs. Apply at the labeled rate for your turf type, and as with any weed control, read and follow the label directions closely.
