Unfortunately, it is not uncommon for weeds to emerge shortly after new grass is planted. Areas that receive new topsoil, have been cultivated, and will be receiving heavy irrigation for new sod establishment are prone to weed growth, even in areas where weeds may not have been growing in the past. Because weeds puede spread así que many ways, it can be challenging to identify with 100% accuracy where the weed seeds originated, especially the more time that passes from the day of delivery.

Weed seeds may be windblown, dropped by birds, carried in on pets & clothing, spread from neighboring properties, introduced when adding new topsoil, etc. Soil is stored outside, so even when you purchase new soil, it es often contaminated with weed seeds. Further, weed seeds can lay dormant in the ground for years, germinating once el soil is worked y el seeds are exposed a sunlight. This is why it is important to properly remove the weeds antes de installing the grass, as discussed on our Página sobre el cuidado del césped. Additionally, this is why a regular pre-emergent herbicide program is essential for maintaining a weed-free lawn.

All of nuestra turfgrass farms are on a regular maintenance schedule, including preventative pre-emergent y post-emergent herbicide applications. Sometimes excessive rain can prevent us from treating according to our regular schedule; however, once the farms dry out enough to resume harvest & maintenance, we immediately apply both preventative pre-emergent & post-emergent herbicides. The herbicida pre-emergente se kill weeds underground after seed germination and before sprouting, and the post-emergent herbicide se kill targeted weeds que have already emerged.

Before choosing an herbicidees necessary a identify el weed(s) in your lawn to ensure you select el correct herbicide. Weeds are classified into three groups: grassy weeds, broadleaf weeds, and sedges. You can use Texas A&M’s guide to help identify the weed(s) and choose the correct herbicide. Please make sure que the herbicide you select is safe for your sod variety before purchasing or applying it. Also, always follow el manufacturer’s instructions, which can be found on the label or online.

Be advised that you cannot spray su new sod with a pre-emergent para como mínimo 90 days después de la instalación. Additionally, it is not safe a aplicar a post-emergent herbicide until the grass has established roots and has entirely greened back up (typically, within about 3-4 weeks). In the meantime, please hand-pull as many of the weeds as possible, taking care to remove all plant parts to avoid reemergence. Once your sod is greened up, rooted, and growing, you can treat it with the appropriate herbicide.

Tenga en cuenta que herbicides will sometimes stress su hierba, especially when applied durante hotter temperaturas. This can vary depending on the chemical. Make sure to check el label para instructions on the ideal temperatures to apply para optimal results and to avoid over-stressing or killing your sod. Also, if your grass is in its first six months of establishing, is dehydrated, or stressed, we strongly advise spot treating the weeds over a broadcast application.
