George Richardson, Technical Director for Peninsular Pest Control, shows us the three types of weeds in North Florida and which ones can be controlled with herbicides.

He also shows the difference between the broadleaf, sedges and grassy weeds and how to treat each type. Learn how the grassy weeds in your flower bed can effect your lawn and how to solve that problem before it begins. Also shown is a yard that has been treated and fertilized by Peninsular Pest Control from the pretreatment through the stages of the yard’s progression up to two weeks after treatment.


One thing to remember is that:  Weed control is a partnership between your lawn care professional and you.  Fertilization and weed control is important…  but it’s up to you to continue to monitor your lawn and do your part in keeping your lawn healthy and attractive.  Just “spraying for weeds” isn’t the total solution.  Let me tell you why:
There are three categories of weeds in North Florida:  Broadleaf, Sedges and Grassy.
Broadleaf weeds are easily treated with herbicides available today, but sedges and grassy weeds are different.  Environmental conditions make it difficult to control them Their condition is usually caused by the environment and they can’t be control, only suppressed.  This is where a healthy lawn becomes important.  It’s the best way to keep these weeds from being a problem.
The third category of weeds is the grassy. There is actually no selective herbicide made to control this type of weed.  Pre-emergent weed control that is applied during the dormant season will help, but the only way to get grassy weeds out of your lawn is to pull them out or to kill the entire area and resod.
Another thing you need to do, or have a lawn treatment professional do for you, is check the pH of your lawn. If it’s too low, for instance, lime needs to be added.  Treating for different pH levels correctly, will give your lawn the best chance to become healthy, which in turn, will help your lawn choke out the weeds.
