Pre Emergent Herbicide – What is it? When to Apply it?

In lawn care, as well as some areas of life, many times it is easier to prevent a problem from starting than to resolve a problem that has already escalated.  In lawn care, this is very true in weed prevention.   For example, it is much easier to prevent crabgrass from germinating than to eliminate crabgrass that is growing and healthy.  This is why a pre-emergent herbicide is so important.


What is a pre-emergent herbicide?  To put simply, it is a product which works to stop weeds very early in the germination process.

Since a pre-emergent has the purpose of stopping the germination process, the pre-emergent should be applied before the time of year in which the targeted weeds germinate. 

So when should you apply your pre-emergent herbicide?  This important question depends on the area in which you live .  In warmer climates, summer weeds will naturally germinate earlier.  Here in the Birmingham area, you should apply and water in your pre-emergent herbicide by mid-March.  As stated in the beginning of the article, it is much easier to handle  summer weeds such as crabgrass before  they germinate than after they become established.

This explains why lawn care companies are hard at work while the grass is still dormant.

Chances are, if you see a lawn early in the year with many weeds, then that lawn was not treated with a pre-emergent in the fall.  If you see a lawn with many weeds during the summer, there is a good chance that the lawn was not treated with a pre-emergent early in the year.
