Thanks to the technology of today, we have become a society built on the convenience of receiving our information in an “instant” fashion. Products such as Vine, Instagram, Twitter, and others were built upon the premise that “smaller is better.” So in the spirit of our technology friends who subscribe to the instant line of thinking, Green Hill Landscaping brings to you 5 Fast Facts about Crabgrass Prevention for your Potomac, MD lawn.
Crabgrass Prevention Should Be Applied When Conditions Are Right, Not by a Specific Date on a Calendar
Often we hear from customers that they want their crabgrass preventer applied as early as possible, getting a jump on the season. However, crabgrass preventer should only be applied when the conditions are right, adhering to an “agronomic” calendar based on weather and soil conditions. If crabgrass preventer goes on too early, you will not get control later in the season.
Crabgrass Doesn’t Germinate Until Early to Mid-May
While it may seem like everything is in bloom in April, the fact is that crabgrass does not begin to germinate until early to mid-May, depending on the soil temperatures. A cold spring can delay this even further. It’s always important that your lawn care company follows an “agronomic” calendar, and not schedule your applications based on how quickly they want to get it done.
You CAN Spot Seed & Apply Crabgrass Pre-Emergent
Seeding your lawn followed by applying pre-emergent crabgrass preventer will indeed prevent the grass seed from germinating. However, this should not stop you from applying crabgrass pre-emergent. As we’ll discuss in Fact #5, cultivating those few bare spots after treatment will break the crabgrass prevention, and allow seed to grow in those areas.
Crabgrass Prevention Should Be Guaranteed for the Entire Season
Run, don’t walk away from lawn care companies who do not guarantee crabgrass prevention for the entire season. Those companies who do guarantee a crabgrass free lawn are more than likely the companies that are applying the product during the correct time, providing your lawn season long protection.
Cultivating The Soil DISRUPTS Crabgrass Pre-Emergent and Breaks Down the Protection
After applying crabgrass pre-emergent, DO NOT cultivate large areas of your lawns soil. This breaks down the crabgrass prevention, and allows crabgrass seed to germinate. However, if you need to spot seed in the spring, apply the pre-emergent over your entire yard and cultivate the soil in those few areas to allow grass to grow.
