The Importance of Pre-Emergent Weed Control Treatments

Stop Weeds in Their Tracks

With spring looming in the not-too-distant future, it’s time to start thinking about your favorite outdoor destination: your home lawn. Between summer parties, barbecues, and general backyard lounging, your yard sees quite a bit of traffic throughout the warmer months. Don’t ruin the experience of a beautiful, barefoot-worthy lawn by letting patches of undesirable weeds take over.
In addition to being an eyesore, weeds compete with your grass for water, light, and essential nutrients.  Not to worry – with a little bit of help from Weed Man’s pre-emergent weed control treatments, you’ll have the power to stop weeds before they grow.  

How They Work

These special herbicides target seeds before they germinate, reducing the opportunity for grassy weeds to sprout.  As the name “pre-emergent” suggests, treatments are applied to the lawn prior to weed growth, and will thus have no effect on existing weeds.  

If you have a history of grassy weeds in your yard, then these last few weeks of winter are critical for creating a lawn care plan catered to eliminating weeds before they grow. If you miss the relatively small window of opportunity, then you will have to take the more difficult route of controlling weeds once they’ve already sprouted.

When applied at the appropriate time, pre-emergent weed control treatments can have amazing results.  Because weed seeds germinate at varying temperatures, knowing the history of your lawn may be helpful. Crabgrass, for example, germinates when soil temperatures reach about 55-60 degrees F for three consecutive nights. Therefore, a pre-emergent treatment applied after this warming period will be ineffective. Depending on where you live and what’s at play on your yard, Weed Man can recommend the best course of treatment to ensure weed seeds never have the opportunity to germinate.  

It is important to remember that weed seeds spread via animals, wind, or foot traffic, which may cause the odd weed to sprout on your treated lawn. In most cases, however, growth will be minimal and can be eradicated using a post-emergent treatment.  

Preventing weeds with pre-emergent treatments is a no-hassle way to fight unwanted growth. Without weeds, your lawn will be better able to withstand common stresses, keeping it hardy, healthy, and pleasing to the eye throughout the seasons.  Contact your local Weed Man today to create a weed control plan that will stop undesirable lawn invaders in their tracks.    

Weed Man Says:

“A general rule of thumb for crabgrass is that if farmers are planting corn, odds are crabgrass has started to germinate. If you have not applied your pre-emergent weed control treatment by this time, you may be out of luck. A good alternative is to use a Dimension formula, which allows you to apply your pre-emergent herbicide a bit later than usual.  If using a liquid application, be sure to go heavy on particularly troubled areas, such as edging, driveways, sidewalks, and curb lining.”
