Pre-emergent herbicides can be an effective way to control broadleaf and grassy weeds before they germinate. These products come in ready to apply granular or concentrated liquid forms. By having your vegetation control contractor include pre-emergent as part of your program, you will improve the curb appeal of your commercial property and increase ROI on your operations dollars. This is achieved by having fewer weeds and a reduction in overall maintenance spend reducing labor cost of pulling & treating weeds.
Pre-emergent works by creating an invisible barrier in the mulch or soil area once applied on commercial property. Weeds are prevented from growing as they come into contact with the barrier. Different pre-emergent products are designed to be effective against different types of weeds so proper selection based on an industrial property's historic seasonal vegetation growth is critical. Some ingredients target annuals on the property, others prevent perennials, and some stop both. It's important that applicators use caution when applying pre-emergent. Products can cause harm to desired plants if contact is made with leaves or roots.
Using pre-emergent is a great way to protect your landscape beds on your commercial property from weeds and keep your property budget under control. With the right partner and carefully selected products, you can take control of your property and keep the weeds away. When choosing a pre-emergent product, we consider factors such as safety for your desired plants. Maintaining effectiveness in controlling the majority of potential weeds for your industrial property and the time of year are at the top of the list as well. For the few weeds that may break through and emerge later in the season, a non-selective herbicide is applied directly on the weed during follow up treatments. It is critical for applicators to always read and understand the label prior to applying pre-emergent weed control. EPA guidance sometimes changes. This is true even for identical products that are in use for years. Testing and application methods improve over time, as do dilution ratios as weeds build resistance in some parts of the country.
Use the right products in the right places on the right commercial property;
When applying pre-emergent, it is important for your vegetation management provider to identify suitable locations where the product will not be quickly broken down by traffic. It can be applied on most landscaped bedding material such as mulch, wood chips, shredded rubber mulch, rocks, and other stone type ground cover. It should be avoided in increased foot or vehicle traffic areas such as driveways and pathways, where a routine application of a combination of pre-emergent and post-emergent products may be more suitable.

For new installations, to help reduce weed growth, landscapers sometimes choose to install a breathable landscape fabric upon installation of new beds, and it’s best practice to always keep a layer of quality mulch around three to four inches thick. Hand pulling weeds is also a good method, but it is important to remove the roots as well. Finally, it is important to minimize traffic on the mulched areas and avoid raking or digging in the bed, as this can disturb the mulch and cause weeds to grow. With these tips, you can keep the weeds out of your landscape and keep your commercial or industrial property looking top notch and kept safe year-round.
