Spring is almost here! The birds are chirping, bees are buzzing and life begins to return to outdoor lawns and gardens. Spring care for bermuda grass lawns is right around the corner. As temperatures start to slowly warm up again, it’s important for us lawn and garden lovers to provide our tender love and care to our beloved bermuda grass lawns.
When it comes to seasonal bermuda grass maintenance, spring lawn care slightly differs from the summer or fall seasons. Temperatures rise and soil conditions change. Bermuda grass is just starting to come out of dormancy and turn green again.
Depending on where you may be located, your bermuda grass lawn may not have even gone dormant at all! Regardless, this is a time to help your warm season lawn transition into the warmer months.
Our turfgrass experts compile a list of spring lawn care tips to help your bermuda grass come out of dormancy and flourish into the spring season ahead.

1. Begin Mowing Your Lawn at the Proper Height Again
The timing for which the first mow of the spring for your mature, established bermuda grass widely varies depending on the area you live in. Bermuda grass can come out of dormancy differently depending on the environment and temperatures your area encounters.
For example, if you live in South Florida, your bermuda grass may have never entered dormancy at all during the winter. Many homeowners who live in South Florida will mow their lawn every other week during the winter—oftentimes starting in September and resuming a regular, weekly mowing schedule again in mid-March.
Generally speaking, mid-March is about the time for you to begin your regimen for spring green-up and mowing. It’s important to note that the first mow of the spring shouldn’t take place while your bermuda grass lawn is dormant—wait until it’s actively growing again before mowing.
The first mow of the spring for your mature bermuda grass will require a buzz-cut of sorts. You will want to drop your mower down a notch below the height at which you usually mow—if not the lowest setting. For most rotary mowers, this means a little more than 1 inch in height.
Pictured above from left to right: A Latitude 36 lawn in the spring and a lawn mower setting.
Over the summer, you won’t cut any more than a third of the leaf blade off, so the grass continues to get taller. People often fall behind the weekly mowing schedule during the summer due to vacation, rainy days, etc. as well. While you consistently leave at least a third of the leaf blade, the grass’s height gets higher and higher as summer progresses so it’s no longer at the lower, ideal height.
The first initial buzz-cut of the spring for bermuda grass gets rid of that excess growth that’s accumulated. You want to get its height back down in the spring as it comes out of dormancy. With grass coming out of dormancy, you aren’t going to hurt it too much and you want to promote fresh growth for the spring.
Be sure to bag your clippings afterward because you’ll have a lot of leaf blade you just removed. Although it’s common to apply the leftover clippings back to your lawn for nutrition, you just removed a large amount of clippings that will result in lumps when you reapply it to your lawn. These lumps of leftover bag clippings will also cause problems like disease or thatch.
After the first initial mow of the spring has taken place, begin keeping your bermuda grass between 0.5–1.5 inches in height.
This same mowing height can be applied to all the various Sod Solutions bermuda grass varieties including Celebration, Latitude 36 and NorthBridge. Don’t remove more than a third of the leaf blade as this may risk scalping the lawn.
Lastly, a good tip for spring is to make sure your lawn mower blades are sharpened so that the mower blades neatly slice through the grass in place of ripping them. If the grass blades aren’t cut neatly, the mower is ripping them and opens the grass up to the possibility of disease.
2. Start Your Lawn Off Right with the Appropriate Spring Fertilizer This Year
With most bermuda grass coming out of dormancy, the spring is one of the most important times to use fertilizer. The best fertilizer for bermuda grass needs to promote healthy roots and the return of green leaf blades.
Be careful when making your first fertilizer application of the year though. It’s common for homeowners to see their grass green up and immediately pull out the fertilizer and lawn mower.
We advise that you typically wait until the last frost has hit—especially if you live in an area that has fluctuating temperatures. If you fertilize your lawn and another frost hits, your bermuda grass will go right back into dormancy and you’ll have a harder time getting it to green up again. This does more harm than good.
The date of the last frost varies from location to location. In the Florida Panhandle, for example, bermuda grass may not go dormant and will reach its full green-up in early February (depending on how cold the winter was). Even then, you won’t want to apply fertilizer until after Easter once the last frost has passed. Refer to the Farmer’s Almanac to figure out the last frost date for your area in 2023.
Sod University recommends two different options for bermuda grass spring fertilization: Lawnifi® Foundation, a slow-release granular option that comes in 25 lb. bags and lasts for three months, and our Lawnifi Spring Fertilizer Box, a liquid fertilizer program that includes three bottles of liquid fertilizer and can be applied monthly with a hose-end sprayer.
Each of the two options are great bermuda grass fertilizers that cover 5,000 sq. ft. Learn more in Granular vs. Liquid Fertilizers or by clicking the two products listed below.
Our patented nano-fertilizers with Catalyst TechnologyTM give your bermuda grass lawn the jump-start it needs to emerge from dormancy, green up fast and thrive throughout the spring months.
Next, it is important to mention that if you have a bermuda grass lawn, you may start to notice spots of brown or straw-like grass while the rest of your lawn comes out of dormancy. This is usually a sign of disease.
You do not want to apply fertilizer to a lawn with disease as the nitrogen in the fertilizer will feed the disease and promote its growth. Apply a systemic fungicide first and then wait several weeks before following with a fertilizer application.
3. Set Up a Spring Irrigation Schedule
Dormant bermuda grass doesn’t need much water until the active growing season kicks in and your grass starts to green up. Once it starts to come out of dormancy, bermuda grass requires about one inch of water per week including rainfall. The same can be said for the different brands of bermuda grass like Celebration, NorthBridge or Latitude 36. If you aren’t sure how to measure how much water your lawn is receiving, an irrigation audit may be beneficial to you.
If you’re a homeowner who lives far enough south and your bermuda grass doesn’t go dormant during the winter, you may continue to regularly water your lawn in the winter.
However, if you live in South Florida, for example, you may turn your irrigation off completely during the winter and during the months of June–August when it rains a lot. The atmosphere in South Florida isn’t usually evaporating much water and the grass isn’t using it much during the winter, so frequent irrigation isn’t needed.
The next few tips in this article discuss spring applications for fungicides, herbicides or insecticides. If any of these control products or fertilizers are granular, you will need to water the product in so that your lawn absorbs it. This means that you will already be watering your lawn with the appropriate amount of water during the week of application.
The same can be said with any liquid products as they are either products that attach to the end of your garden hose or require tank mixing with water.
Above all, read and follow label instructions thoroughly before watering any products in.
4. Control Weeds with a Pre- or Post-Emergent Herbicide
A pre-emergent should be applied during the spring when ground temperatures reach about 55 degrees Fahrenheit. A pre-emergent herbicide functions to prevent weeds from emerging from the surface of the soil, as its name suggests.
The exact dates for these applications differ depending on the area you live in, but generally speaking, pre-emergents should be applied between the beginning and middle of March in the spring.
Post-emergent products containing multiple broadleaf active ingredients like SpeedZone Broadleaf Herbicide for Turf are the best spring lawn treatments as they are more effective in controlling broadleaf weeds. If you start to notice grassy weeds such as crabgrass or goosegrass, post-emergents like Drive XLR8 and Mesotrione 4 SC Select will treat them.
Be sure to follow product labels appropriately during application. Lastly, if you notice weeds and you aren’t sure which type of weed it is, check out our Identifying Common Lawn Weeds blog.

5. Watch Out for Insects That May Begin Coming Out
If your lawn has suffered from insect damage around this time in the past, it is a good idea to apply a broad spectrum insecticide at this time to prevent them from coming back again. If the insecticide is a granular product, be sure to water it in so that it soaks into your soil. On the other hand, if it’s a liquid product, you will either need to attach it to the end of your garden hose or tank mix it.
Some of the most common spring insects in bermuda grass are white grub worms and sod webworms. Sod webworms are typically more of a summer or fall pest, however, they can still cause a significant and costly nuisance to lawns located throughout the Southern regions of the U.S. during the spring season.
Acelepryn is often used to treat currently existing grub worm infestations that may show up in the summer whereas Imidacloprid-based products like Imidacloprid 2F, which is included in the Lawnifi Complete Program, Merit 0.5 G and Merit 2F prevent them as it begins to warm up in the spring.
Imidacloprid 2F, Merit 0.5G, Merit 2F, Hi-Yield Bug Blaster Bifenthrin, Bifen L/P and Bifen XTS can prevent some of the most common lawn insects.
You can read more about these insects in our Insect Identification blog. Refer to some of our most popular and effective insect control products below and be sure to follow product label instructions before application.
If you notice any disease outbreaks, you may need to make applications of a systemic fungicide like Azoxy 2 SC Select, which is included in the Lawnifi Complete Program. Even if you don’t have disease in your lawn, it’s still good practice to apply it preventively to keep disease from taking over—especially if you’ve had disease in the past around this time.
Systemic fungicide applications should take place before you apply any spring fertilizer. If you have fungus in your lawn, the nitrogen found in fertilizers oftentimes feeds it and helps it spread. Apply a systemic fungicide and wait a few weeks before applying any fertilizer.
There are a few other optional things that can be done to help your lawn thrive in the spring.
Before the onset of summer heat, lawn patchwork and light top dressing with a sand and topsoil mix is a great way to recover any weak areas. Plugs can be purchased to fill in areas of the lawn with bare spots. Learn more here.
Aerating your lawn is also an ideal way to help deliver nutrients and really break up compacted soils. We typically recommend doing this once every couple of years. If you notice thatch that is thicker than 1⁄2 inch, dethatch in late May. Read more in Aerating vs. Dethatching.
