1. Scotts Turf Builder Halts Crabgrass Preventer with Lawn Food

Scotts Turf Builder Halts Crabgrass Preventer with Lawn Food

A great choice for preventing crabgrass and other weed species is Scott’s Turf Builder. This product is great because it feeds your lawn while preventing crabgrass seeds from germinating, thereby helping your lawn thrive season after season.

You can apply Scotts Turf Builder Halts Crabgrass Preventer with Lawn Food to your lawn after winter to green it up quickly. The product’s performance won’t be affected by snow or very cold weather after application.

Give your lawn around a half inch of water within two days of applying this turf builder. If your lawn gets water from rain, then you won’t have to do any extra watering, but if there’s no rain forecast, then you’ll have to water it yourself.

Scotts Turf Builder will not work on bentgrass or dichondra lawns, but it can be used on many other types of turfgrass. There are a variety of grasses, such as Zoysia, Bermuda, Kentucky Bluegrass, Centipede, and Fescue, to name a few.

It will prevent not only crabgrass, but also poa annua and chickweed from germinating in the spring. Your lawn will be protected all year long.

Bonide Crabgrass and Weed Preventer for Lawns and Ornamental Beds

A pre-emergent crabgrass herbicide, Bonide Crabgrass and Weed Preventer for Lawns and Ornamental Beds prevents crabgrass in lawns and ornamental beds.

In the spring, when the soil temperature is 45-50 degrees Fahrenheit, you should apply it to your lawn. If you use this product, you won’t have any problems with crabgrass or other weeds (such as barnyard grass, annual bluegrass, chickweed, foxtail, spurge, and goosegrass) throughout the year.

You can use this product up to a month later than many other crabgrass prevention products and it will still be effective. With Bonide Crabgrass and Weed Preventer, you can keep weeds at bay for up to four months. It should not be necessary to reapply if your lawn is healthy and established since your lawn canopy should prevent light from reaching crabgrass seeds at that point.

This product covers 5,000 square feet of lawn. It’s a smaller bag, so you may need more than one to cover your entire lawn. In addition to being a granular product, BONIDE 60400 can be applied to both warm-season and cool-season grasses.
