Here at Tri-Hill Turf & Pest we recommend a Pre-Emergent on the customer’s lawns we care for with our lawn programs.

We will use a pre-emergent in the fall and spring to help prevent weeds from germinating its seed. The pre-emergent is the barrier that helps keep the weed seed from germinating and competing with your desired turfgrass. This “barrier” does not prevent all weeds, but it definitely gives your turfgrass an advantage in thriving and giving you the look that you want: as healthy and as lush as your lawn can be in your setting.

Pre-emergents are good for things such as Henbit, Annual Bluegrass, Fireweed, Crabgrass and weeds that grow from seed every year (annuals). It is not as effective on perennial weeds such as Dandelion, Johnsongrass, Dallis grass, Nut Sedges, Bahia, etc. All of these have life cycles that can last two or more years. For the tough perennial weeds, a post-emergent product has to be used to help control the pesky weed once it is actively growing.


Now, if a pre-emergent is not used, you will see the difference. While a pre-emergent may only control 75% to 90% of the weeds, that control is important to help your grass out-compete these weeds, which thrive on the same water and nutrients your desirable grass does.

Pre-emergents have to be watered in, and we will leave instructions on when to do so, usually within a week or so after application. Around here, we normally receive a little rain to facilitate this, but you will need to break out the sprinkler to realize the full effect of this important application if not.

Pre-emergents are also important because they help unleash your lawns ability to out-compete these weeds. Once your grass is green and growing in the spring, it will just have less competition for the water and nutrients and outgrow and shade out most weeds that want to get growing. Pre-emergents also help reduce the need for post-emergent treatments. The old adage of “an ounce of prevention is worth a pound of cure” definitely holds true here.

If you are skipping any steps in your lawn care program, make sure not to skip your pre-emergents. They are fundamental steps to growing an attractive lawn.

This is an important step, in addition to proper mowing and watering, timely treatments, and a balanced fertilizer. Following these steps will help you reach your goal of having an attractive lawn, and it will make your home look more inviting.
