Spring Pre-Emergent:  How Does it Work?

If you have been with a lawn and landscaping service for a while, you are probably aware that the first rounds of fertilizer and weed control include something called a pre-emergent.  

What is it?  Simply put, pre-emergent is a weed killing chemical, but the primary difference between that and a post-emergent, as you can imagine, is that pre-emergent kills the weeds before they germinate.

However, it is important to note that you cannot apply pre-emergent at any time during or before the spring.  For it to be effective, there are a few factors to consider before either spraying it on your turf or even if it is combined with a simple granular application fertilizer. 

  1. Consider the temperature. 
  • A pre-emergent will not be effective at colder temperatures because it may break down without penetrating the soil before it has a chance to activate during the germination process. For best results, apply when soil temperatures are at least 50 degrees. 

2. In order for it to work, pre-emergent must be watered in. 

  • Now, that does not mean you need a sprinkler system. Rainfall of half an inch will suffice if you cannot water it in yourself before seven days after application. 

3. In general, keep in mind that most pre-emergent will not work on some broadleaf weeds like dandelions. 

  • The main weeds controlled by pre-emergent are destructive and unsightly grassy weeds such as crabgrass (Always read the label to know what kind of control you will get). 

4. After temperatures reach a certain point pre-emergent will not be effective because most weeds have already germinated by then. 

  • The idea is to have a layer of protection before they start growing. One caveat: Not all pre-emergent are equal in what they control or their effectiveness. Always read the label.

One final note:  if you are seeding in the spring, you cannot apply pre-emergent because it will kill the seeds that have or will be put down; pre-emergent must be given at least eight weeks to penetrate the soil after application before seeding. If you plan on doing spring seeding, wait until the fall or the next spring to put down pre-emergent (or, better yet, consider seeding in the fall). As you can see, a lot of timing is involved when getting the most out of weed control, which can seem overwhelming without experience and the free time to take care of it.

Springtime Tips and Tricks

As we transition from Winter into Spring here are a few quick tips to get things going.

Prune back dead or damaged trees or shrubs to the live stems where they have been damaged by cold, snow, and wind. Overgrown evergreens should be cut back to a branch for which you want to encourage growth. During this time of year, it is also a good idea to prune perennials.  

Get your patio or deck ready for the upcoming season by washing it down. This can take years off the look of your patio and rejuvenate your interest in spending more time there.

Make certain that your gutters and downspouts are clear of leaves and debris. By blocking gutters and downspouts with leaves and debris, rainwater may not drain properly. Overflowing gutters can cause water damage both to the interior and exterior of your home. 

Make sure you remove all leaves and dead foliage from your lawn and beds, as they can smother your plants and cause disease. You can also pull up last year’s annuals if you haven’t already done so.

The coming weeks are the best time for fertilizing and laying down pre-emergent to green up your lawn and prevent weeds. Deep roots that form in spring help to improve the turf’s vigor during the summer when it is hot and dry. If you have questions on pre-emergent stay tuned for next weeks blog where we will provide some in-depth information regarding it.

Plan how you will use your outdoor space this upcoming season. How are you going to utilize your landscape? Do you want a new patio, outdoor fireplace, or a refresh of your landscaping?
