What Is Centipede Grass?
Centipede grass is a low-maintenance, warm season turfgrass commonly found in yards and gardens. It grows best in sandy soils and has an excellent drought tolerance. Its bright green color and fine texture make it an attractive choice for many homeowners looking to fill out their lawns with lush coverage.
What Does Centipede Like?
In order to maintain a healthy centipede grass lawn, there are certain environmental conditions that need to be met. Centipede grass thrives in full sun and well-drained soils. It prefers acidic soil with an optimal pH of 5-6. It is important to provide regular irrigation during periods of drought or extended dry spells.
Additionally, adding a layer of mulch can help retain moisture for the grass and will also reduce the amount of weeds in the area. Centipede grass requires very little fertilization and should only be done when necessary; too much fertilizer can lead to problems like leaching, burning, and disease. [1]
Common Centipede Grass Problems
Dollar Spot
Dollar spot is a type of fungus that can cause brown spots on the surface of Centipede grass. It usually appears in hot, humid weather and is caused by poor soil drainage. To treat dollar spots, apply a fungicide according to the directions on the label.
Chinch Bugs
Chinch bugs are small insects that suck sap from grass blades, causing them to dry out and turn yellow or brown. They’re most active during late summer months when temperatures reach above 80 degrees Fahrenheit. To get rid of chinch bugs, apply an insecticide according to the directions on the label.
Grub Worms
Grub worms are a common problem that can plague centipede grass. These white, c-shaped insects feed on the roots of your lawn and create brown patches where the turf has been killed off. To identify grub worm damage, examine the soil around affected areas. If you see several small curved larvae in the top few inches of soil, you may have a grub worm infestation.
Treatment for grub worms typically involves chemical pesticides or beneficial nematodes to kill them off. For more information about dealing with grubs in your lawn, contact your local extension office for advice on treatments and prevention methods. [2]
Mole Crickets
Mole crickets can also be an issue for centipede grass. These pests feed on the roots of the turf, causing small holes in the lawn that appear as little piles of dirt next to yellow spots. If you suspect mole crickets are lurking beneath your lawn, use a spade or shovel to dig around affected areas and inspect for these insects.
Similar to grub worms, chemical insecticides are typically used to treat mole cricket infestations. However, some species of beneficial nematodes have been found effective against mole crickets as well. Be sure to follow all label instructions when applying any chemicals and avoid treating during periods of extreme heat or cold.
Spittlebugs
Spittlebugs may also be a problem in centipede grass. These insects create white, foamy masses on the leaves of affected plants that can cause discoloration and stunted growth. Spittlebugs are not typically considered serious pests but they can become quite bothersome if left untreated.
To control spittlebugs, use insecticidal soaps or horticultural oils to smother them without harming your lawn. Beneficial wasps or lady beetles have also been known to feed on these pests, helping to minimize their population in a natural way. It is important to remain vigilant when caring for any type of lawn turf, including centipede grass. [3]
Ground Pearls
Ground pearls are tiny white balls, about the size of a grain of sand or smaller, that form from calcium carbonate in centipede grass. They often appear on the surface of lawns in dry periods and can be especially problematic when they accumulate to form mounds. If your lawn is being plagued by ground pearls, rake them up and dispose of them.
To prevent further problems with ground pearls, increase irrigation during dry periods and make sure your soil pH is between 5.5-6.0; if it’s higher than 6, lower it with an iron sulfate application.
Brown Patch
Brown patch is a fungal disease that affects centipede grass and other types of turfgrass. It looks like an expanding circle of brown turf, with a dark border surrounding it; the area can be several inches to several feet in diameter. The fungus thrives in humid climates and during hot summer months when grasses are under stress from lack of water or over-fertilization.
To prevent brown patch, keep your lawn well-watered but not overly saturated, and avoid over-fertilizing. If you suspect your lawn has been infected with brown patch, apply a fungicide according to label instructions for best results. [4]
Over Fertilizing
Centipede grass is a low-maintenance turfgrass and requires very little fertilizer. It can be easily damaged by over-fertilizing, resulting in brown spots or yellowing of the grass. To avoid this, use only a slow-release fertilizer with an analysis of 8-4-4 or 10-10-10 if the lawn needs fertilization. Applying too much nitrogen can cause excessive thatch buildup which may lead to infestation by chinch bugs, sod webworms, and brown patch fungus.
Thatch
Thatch buildup can also occur if the lawn is mowed too short. It is best to maintain a mowing height of 1-1/2 to 2 inches as this will help reduce thatch buildup and prevent insect infestations. It’s important to water centipede grass deeply, but infrequently. Watering too much can lead to an accumulation of shallow roots which makes the grass more susceptible to drought and prone to damage from heavy traffic. Conversely, not enough water causes it to dry out and become dormant during dry spells.
Effects Of The Weather On Centipede Grass
Centipede grass is susceptible to several weather-related problems. In cold winter climates, freezing temperatures can cause the grass to become dormant, leading to decline in overall health. If the temperature drops below 15 degrees Fahrenheit for an extended period of time, the turf may not survive.
Centipede grass may also experience significant damage from heavy traffic or improper mowing heights that cause excess stress and weaken the turf. In order to ensure a healthy lawn, it is important to provide adequate irrigation and drainage when appropriate, mow at the recommended height for centipede grass, reduce traffic as much as possible, and use pest control methods only when needed.
With proper care, this type of grass can be an attractive and durable lawn solution in many climates. [5]
Nutrient Deficiencies
Centipede grass is naturally low in nutrient requirements, but if not properly fed and maintained, it may suffer from a lack of essential minerals. Symptoms of nutrient deficiencies can include yellowing or discolored patches and weak turf.
To keep the grass healthy and vigorous, regularly apply fertilizer that is formulated specifically for centipede grass throughout the growing season according to manufacturer recommendations.
Also be sure to check soil pH levels periodically as an acidic environment can result in increased nutrient deficiencies.

- Treat pests – Check centipede grass regularly for signs of pest damage such as yellowing leaves or dead patches. If you identify any pests, use a pesticide formulated specifically for centipede grass. Make sure to follow the label instructions and wear protective gear while applying it.
By following these tips you can help keep common centipede grass problems at bay and maintain a healthy, beautiful lawn that will last for years to come. [6]
How Long For Centipede Seed To Germinate?
Centipede grass will germinate in approximately 7-10 days after sowing, provided the conditions are right. The ideal temperature range for germination is 75–85°F (24–29°C) with soil moisture kept at a moderate level. If temperatures drop below this range, it can take longer for the seed to germinate.
In addition, soil that is too wet or dry can cause delays in germination as well. It’s important to make sure the area where you’re planting your centipede grass has good drainage and keep it evenly moist throughout the growing season. Too much water can lead to disease problems like root rot, while too little water causes stress on the plants resulting in yellowing and wilting.
If you find that your centipede grass is taking longer than expected to germinate, then check the soil moisture and temperature levels again as well as the quality of your seed. Taking a few extra steps can help ensure a healthy and vigorous lawn in no time!
How Should I Mow Centipede Grass?
When mowing centipede grass, it is important to keep the blades on your lawnmower sharp. Dull blades will tear or rip the grass instead of giving it a clean cut. In addition, you should use a mower with a low setting, typically 1-2 inches high. This will help keep the grass healthy and prevent it from becoming stressed out.
When possible, you should also avoid scalping your centipede lawn; never remove more than one-third of the blade’s length when cutting. Lastly, don’t forget to collect clippings! Leaving them on the lawn can lead to thatch build-up and other problems with your centipede grass.
It’s also important to mow regularly, preferably every 5-7 days. This will help the grass stay healthy and prevent it from becoming overgrown. During high-growth periods like spring and summer, you may need to mow more frequently. In addition, try to avoid using a bag when collecting clippings; research has shown that leaving them on the lawn can benefit centipede grass health by providing extra nutrients.
By following these guidelines, you can keep your centipede grass looking great while avoiding common problems associated with overgrown or unhealthy turf. A little effort and maintenance now can mean healthier grass and fewer headaches in the future!
How Can You Make Centipede Grass Thicker?
Making centipede grass thicker is possible, but it requires careful attention to its growing conditions. The best way to promote thick growth of centipede grass is through proper lawn maintenance practices. To begin, mow the grass regularly at a height of 1.5-2 inches and water thoroughly when soil appears dry.
Additionally, fertilize your lawn once or twice a year with a fertilizer specifically designed for centipede grass such as an 18-0-6 or 16-4-8 formulation.
Finally, make sure that your yard has good drainage; standing water can create problems for healthy grass growth and lead to disease issues. By following these steps, you should be able to improve the thickness of your centipede grass over time. [7]
Overseeding An Existing Lawn With Centipede Grass
Overseeding an existing lawn with centipede grass can be a tricky process. If done correctly, however, it can help keep your lawn looking lush and healthy for years to come. The first step is to identify the type of grass you already have in your yard and how thick it is. Once you’ve identified this information, you should then apply a pre-emergent herbicide before overseeding with centipede grass.
By following these steps, you can successfully overseed an existing lawn with centipede grass and enjoy a lush, healthy lawn for many seasons ahead. Just remember to stay vigilant when it comes to common centipede grass problems such as fungus, disease and weeds in order to keep your lawn looking its best. With proper maintenance and care, centipede grass can be an excellent choice for your home’s landscaping needs!
