Spring marks the return of lawn maintenance and the constant battle to rid the lawn of crabgrass. Crabgrass (also known as finger-grass) is a pesky lawn weed with a slender stem that grows out of the plant and has leaf blades that grow near the ground. The stem produces seeds from mid-summer to fall. The plants die each winter and new plants grow each season from seeds.
Crabgrass Prevention Products
Crabgrass prevention products, such as Scotts Halts Crabgrass Preventer, prevent the seed from taking root and becoming a plant. Crabgrass prevention products are generally applied in early Spring. A crabgrass prevention product does not work well with new grass seed. The product will also work to prevent the grass seed from sprouting. A homeowner must make a choice on which lawn problem to tackle first, bare spots in the lawn or crabgrass prevention.
Some products, such as Scotts Turf Builder With Halts Crabgrass Preventer, contain fertilizer and crabgrass prevention in one product. The fertilizer in the product feeds existing grass plants, it will not assist new grass seed in taking root. The crabgrass barrier will still work to prevent new grass seed from sprouting.
Scotts Halts Crabgrass Preventer and Scotts Turf Builder With Halts Crabgrass Preventer are granular products which can be spread over a lawn in the same manner as grass seed. Crabgrass prevention products do not work well with all types of grass, such as dichondra or bentgrass. Read the label before spreading over a lawn.
Crabgrass Killer Products
Crabgrass killer products, such as Ortho Weed B Gon Max Plus Crabgrass Control, work to kill the plant after it has taken root and begun to sprout. The product is sprayed directly onto the weed with a trigger applicator and is rain-proof within one hour. The active ingredient will target the root, thus killing the plant. Crabgrass killer products are not suited for all types of lawns. Ortho Weed B Gon Max Plus Crabgrass Control should not be used on floratam, centipede or bahiagrass lawns.
Other crabgrass killer products, such as Bayer Advanced Concentrate All-In-One Lawn Weed And Crabgrass Killer or Spectracide Weed Stop For Lawns Plus Crabgrass Killer, require mixing with water before applying. These products can be used in a container that attaches to a garden hose and sprayed over a lawn. The product also targets the root and is generally rain-proof within one hour.
Crabgrass Prevention and Killer Products
Some products, such as Preen Lawn Crabgrass Preventer, will work to prevent crabgrass from sprouting if applied in early Spring and also work to kill seedling sprouts. This type of product should be applied to a well established lawn. The crabgrass barrier will work to prevent grass seed from sprouting also.
