We work hard to keep our lawns looking beautiful. Sometimes, despite our best efforts, we end up having with pests and
weeds. One Utah lawn issue that you may encounter this month is Crabgrass. With a little work and some preventive maintenance, you can keep your lawn looking beautiful this year and many years to come.
Crabgrass begins germinating when temperatures average between 55-60 degrees Fahrenheit. Depending on how the seasons progress, this temperature range can occur between late spring and early summer. Once it starts, it continues to reproduce throughout the summer and into the early fall. Only the frost of late fall will kill it for the season.
There are herbicides you can purchase to treat your lawn and prevent crabgrass from growing. Your best choice is a pre-emergent herbicide, which means that you use it before the crabgrass appears. These herbicides kill the seeds before they germinate and may need to be reapplied during the summer months.
These herbicides come in either a liquid or granular form. It is important that you apply them at the right time. If you apply it too early or too late in the season it won’t be effective. If you want to know the best time to apply the herbicides you can follow the adage that says to use it “After the forsythia bushes bloom but before lilac bushes bloom”.
You need to make sure that you water your lawn after you apply the herbicide to help activate it but don’t aerate your lawn afterwards. If you aerate your lawn after applying the herbicide you risk damaging the protective layer of the treatment that prevents crab grass germination.
Utah lawn care is a consistent task that requires preventive maintenance as well as constant monitoring during the season. Starting your work early will help make your work easier the rest of the year. Then you can spend some time enjoying the lawn you worked so hard to cultivate.
What should I do if I start seeing crabgrass?
You may have already started seeing crabgrass and other summer annuals in the cracks of your sidewalk or driveway. This is an indicator of the weeds that may soon infiltrate your lawn. You should have already received a first application of pre-emergence. A second application will help reinforce the pre-emergence barrier, and therefore prevent many of these weed-seeds from taking root and infesting your lawn.
The pre-emergence window closes fast…Act now and keep that nasty crabgrass out!
During the month of July, you may begin to see instances of weeds on your Utah lawn. For this month begins the peak growing season for many different weeds. One of the main weeds that you may see is crabgrass.
The Stubborn Enemy
Crabgrass is a very stubborn enemy. It can germinate for long periods of time and can appear on your lawn throughout the growing season. It spreads many seeds in the late summer and fall, and it is tolerant to heat and drought. Once crabgrass roots in your lawn, it can be difficult to remove.
Not Easy to Spot
Crabgrass is often misidentified. Not all thick bladed grass is crabgrass. In actuality, this weed grows close to the ground and spreads out. So, if you see tall, thick bladed grass on your lawn you may not have crabgrass. Instead, you may have a different type of grass that was planted by a previous owner that is now growing on your lawn.
What Does It Do?
It has root toxins that spread in the soil to make the turf around the crabgrass look dull and lifeless. It is also very prolific, and once it starts it can spread across your lawn rapidly.
How to Prevent
You can prevent crabgrass from taking root on your Utah lawn. By mowing your lawn at the second highest setting you are leaving the grass high enough that it can cast any potential crabgrass in the shade. Crabgrass prefers sun to grow to you are making it difficult for the weed to thrive when leaving your grass tall.
You can also make changes to the soil so that the crabgrass doesn’t find the ground palatable to grow. You may see instances of crabgrass in your lawn, but not your neighbors because their soil is different.
