The Pre-Emergents I Tested

The [Scotts Halts Crabgrass Preventer](https://www.amazon.com/s?k=Scotts+Halts+Crabgrass+Preventer&tag=thetestedhub-20) was the easiest to spread evenly and gave me clean control through the full ten weeks.

The Pre-Emergents I Tested

I compared five lawn pre-emergents across my front yard, back lawn, and a neighbor's crabgrass nightmare to see which actually stop weeds before they sprout.

Common questions

When should I apply pre-emergent?

Soil temperature is the trigger, not the calendar. I apply once soil hits a steady 55 degrees Fahrenheit for three days. That is usually mid-March in my zone.

Can pre-emergent kill my existing grass?

If applied correctly, no. But it will block new grass seed from germinating, so never apply pre-emergent and seed in the same season.
