Barricade review.

By Jack in Decatur, AL on 03/03/2023

Not Best
2 of 5 stars
By Sylvia in Homeland Ca on 04/12/2025

This has not worked for me. After a light rain they sprouted.

Expert Response  Expert response:

While pre-emergent herbicides are an important tool in weed prevention, there are several factors that can affect their performance. Timing is one of the most critical—if the product was applied too early or too late in the season, some weeds may have already germinated or remained dormant, reducing the treatment's effectiveness. Additionally, inadequate soil moisture, heavy rainfall after application, or improper lawn preparation can all impact how well the product activates and binds in the soil.
