Stop Annual Grasses Before They Start
The season can be saved with pre-emergent controls
Annual grasses like crabgrass are extremely aggressive. Without treatment, they’ll thin and choke out your good grass as they compete for growing space in your lawn. In just a few years, you could be left with little or no healthy turf.
A short life span enables annual grasses to mature quickly, appearing in your lawn without any warning. Though post-emergent herbicides are available to treat annual grasses after they sprout, prevention is recommended in order to keep your lawn thick and healthy.
Early spring is the ideal time to take preventative measures. By applying pre-emergent herbicides, we can help to eliminate the chances of annual grasses establishing a foothold in your lawn this growing season.
How pre-emergents work
Pre-emergent herbicides literally form a barrier in the top inch of your soil which blocks annual grass seeds from sprouting. As the seeds germinate, they are immediately killed off by the herbicide. Young seedlings that may have sprouted before the pre-emergent was applied are eliminated as well.
Once is not enough
There will always be annual grass seeds in your lawn. In fact, crabgrass seeds can remain in your soil for up to 30 years before sprouting. Annual grass seeds can also be blown into your yard from miles away in windy conditions. For these reasons, yearly applications of pre-emergent herbicides are necessary for maximum prevention and control.
Planning on seeding this season?
Pre-emergent herbicides prevent all types of seed from germinating, so it’s a good idea to wait six to eight weeks after an application before planting any new grass seed.
