Fall Maintenance Tips for Your Centipede Lawn

It’s the first day of fall and with the changing of the seasons also comes the changing of temperatures, weather and soil conditions. It’s important that your centipede lawn undergoes the proper maintenance during this time of year. Read on for a list of generic tips to help your centipede lawn transition into the colder months ahead. Be sure to also check out our Homeowner Maintenance Guides for generic centipede and Santee® Centipede. If you’re looking for maintenance tips for a different type of grass, take a look at our Fall Lawn Maintenance Tips article.

Fall Mowing for Centipede

Centipedegrass is generally mowed at a height between 1.5–2 inches in height. During the fall, however, you should maintain a height that’s slightly higher than that of the summer. This encourages deeper root growth so that your grass survives during winter dormancy in the cooler months. This sets your grass up for survival during its dormancy period as the roots are what keep the grass live underground while the blades above ground endure harsh temperatures. For more information on mowing heights, visit our Lawn Mowing Guide.

Fall Watering for Centipede

In the fall, you will want to water the centipede less than other times of the year as temperatures begin to drop. If you water your grass too much, it could lead to disease during this time. Your centipede generally only needs about one inch of water weekly including rainfall. You will actually want to water a little less than this during the fall months, though, because fall is one of the most opportune times of the year for fungus to start appearing. This becomes even more likely if you are overwatering your grass or have fall leaves on the ground that create areas of shade. You will want to water to prevent drought stress while the grass is still actively growing, though. Light watering during dormancy will also prevent dehydration and watering in the early morning will decrease the risk of certain turfgrass disease.

Fall Fertilization for Centipede

Fertilization differs this time of the year compared to the other active growing seasons for your centipede lawn. This is the case for most turfgrasses. As previously stated, outdoor temperatures are starting to change, and so are soil conditions. Your grass is a living thing that needs specific nutrients at this time. This is why Sod University loves the LawnifiTM liquid fertilizer program. It consists of three individual fertilizer boxes for each of the active growing seasons for spring, summer and fall. The Fall Fertilizer Box, in particular, has three separate bottles of fertilizer in it that help your centipede lawn recover from the hot summer temperatures it just endured as well as prepare for the colder temperatures ahead.

In the early fall, you will start off with applying Boost to revitalize the green leaf blade color after the heat of summer. The rapid green-up of your lawn will last from the time of application through the remainder of the growing season with Boost’s time release formula. In the mid-fall, you should make an application of the second bottle in the box, Maintain, for well-balanced nutrition. Maintain serves to help with color retention late into the cooler months ahead and fortifies the root system to help it survive throughout dormancy or snow. In the late fall, you should apply Recover to prepare your lawn for environmental stressors of this colder weather.

Fall Weed Control for Your Centipede

Your centipede lawn has just made it through the heat of the summer—this is the time when it is not a recommended time for herbicide applications due to hot temperatures. Now that it is starting to cool down, you are free to apply both post-emergent and pre-emergent herbicides without risking any damage to your lawn. You may even notice that the weeds from summertime are starting to die off.

Unfortunately, there are winter weeds that will start to pop up when the months are colder. A post-emergent herbicide controls any current weeds you are experiencing whereas a pre-emergent herbicide, as its name suggests, serves to prevent weeds from appearing. Fall is actually the best time to apply a pre-emergent—especially if winter weeds have been a big problem in the past years. If you decide to apply a post-emergent herbicide instead, it should be noted that centipedegrass and St. Augustinegrass are both sensitive to chemicals like 2,4-D, dicamba, MSMA and MCPP. A post-emergent containing the active ingredient Atrazine, like Southern Ag Atrazine and Spectracide Weed Stop For St. Augustine and Centipede Lawns are better options.

You can also do this in the springtime around March or April. Read more about pre-emergent applications in the fall in How to Use a Pre-Emergent Herbicide in the Fall. Some hard to control weeds that may appear around this time include chickweed, henbit, Poa annua, crabgrass or goosegrass.

Fall Insect Control for Centipede

It is better to apply an insecticide as a preventative as opposed to having to resolve an infestation once damage has already occurred—it’s probably less expensive too. Apply a broad-spectrum insecticide to prevent any harmful insects from taking over your centipede. Although there could be a variety of insects that may be invading your lawn at this time, the main ones most universities recommend you look out for in your centipede are grub worms. If you have insect activity, treat with an insecticide labeled to treat the insect you are seeing. If you use a granular variety, water the lawn immediately after application to help with absorption.

Fall Fungus Control for Centipede

This is the time of year for fall fungus outbreaks like large patch. If large patch or other diseases are a common problem in your centipedegrass, apply a fungicide at a preventative rate. This will help the grass enter colder months in a healthier condition. If you have had a fungus before, you may need to make multiple applications in affected areas. If you use a granular variety, water the lawn immediately after application to help soil absorption. Consider mapping those areas because fungicide treatment can be expensive.

Lastly, lawn patch work and light topdressing with a sand and topsoil mix is a great way to recover any weak areas in your lawn that were caused by the summer heat. If you notice any hot spots, apply a light layer of topdressing to help it recover.
