New sod turning yellow or brown in Tampa can trace back to watering, fertilizer, soil prep, heat, bugs or disease. UF/IFAS Gardening Solutions says new sod needs light, frequent watering for the first 2 to 3 weeks, so start with the water. St. Augustine sod installed runs $0.98 to $1.79 per square foot, and removing weeds and old grass adds $0.88 to $1.84 per square foot (national ranges, 2026); what the fix involves depends on which cause you find.
Whether it can wait depends on the season and the cause. UF/IFAS says summer heat can quickly dry out rootless new sod, so a yellowing lawn in its first weeks is worth a look this week. Below: the causes, the checks you can do yourself, Tampa's watering rules for new sod, and what a fix costs.
Why new sod turns yellow or brown
New sod turning brown or yellow can have more than one cause at once. Go through these one at a time and write down what you see.
Watering that is uneven, too little or too much
UF/IFAS says to give new sod light, frequent watering for the first 2 to 3 weeks, so the soil stays moist but not soggy, then taper off once it roots. A Tampa yard can miss that target from two sides. UF/IFAS says North and Central Florida soils are typically very sandy and do not hold water or nutrients well. At the other end, many Florida flatwoods soils have a water table that rises to within 5 to 20 inches of the surface, which is why some Tampa yards pond after rain.
Before you patch dead areas, UF/IFAS says to find what killed them. Check the sprinklers for missed or overwatered spots, and look for insects or disease. A strip that sits where a sprinkler head does not reach, or a patch that stays wet, tells you something about the cause.
Sod yellow after installation: it waited too long before it went down
Timing matters before the first roll is unrolled. UF/IFAS says to lay sod within 24 hours of delivery and to lightly water the soil just before you start. The UF/IFAS Extension office in Hillsborough County says to lay sod within 48 hours of cutting. If your sod looks stressed from day one, ask the installer when it was cut, when it was delivered and how long it sat before it was laid.
Fertilizer that went on too early
UF/IFAS advises 30 to 60 days before fertilizing new sod, and 3 to 4 weeks before the first mow. It also notes that early fertilizer is a common reason new sod struggles. Tampa adds its own calendar: lawn and landscape fertilizer with nitrogen or phosphorus may not be applied from June 1 to September 30 (City of Tampa), and none goes within 10 feet of water.
Soil and site prep that was skipped
Before sod goes down, UF/IFAS wants the soil tested for pH and nutrients and graded evenly so it slopes away from the house. The Hillsborough County Extension office gives a target of a soil pH of 6.5 to 7.5 with about 5% organic matter. The median Florida soil pH is 6.1, slightly acidic, and UF/IFAS says to amend only when a soil test shows a need.
The same Hillsborough County guidance says to rototill compacted soil 6 to 8 inches deep before laying sod, and never to lay sod over existing weeds and grass: remove or kill them first. That matters in Tampa, because UF/IFAS Extension Hillsborough County says urban development in Tampa and Hillsborough County often leaves compacted, nutrient-poor sandy soil.
Heat, dry months or a cold night
UF/IFAS News says spring is usually the ideal time to lay sod in Florida, though sod can root in any season if the ground is well prepared. Summer heat can quickly dry out rootless new sod, while summer rain helps it grow. Tampa has about 94 days a year at 90°F or hotter, and August's normal high is 91.2°F (NOAA climate normals).
Dry months matter too. November is Tampa's driest month at 1.40 inches of rain in a normal year, so new plantings in the dry months lean on irrigation. As for cold, Tampa averages less than 1 night a year below freezing (0.8). Ask whether a freeze night actually came before you blame the weather.
Bugs and disease that look like a sod problem
Yellow and brown patches are also what some lawn pests and diseases look like. UF/IFAS says chinch bug damage shows as yellow to brown patches, and heavily infested St. Augustinegrass turns yellow first, then quickly dark brown. Chinch bug injury usually shows first in grass that is water-stressed or in full sun. Our page on chinch bug dead patches covers the check in detail.
Large patch, often called brown patch, is a fungus that shows up mostly when temperatures drop below 80 degrees, usually November to May in Florida. It starts as round patches with a brown, sunken center, and the edges are darker, sometimes orange, where the fungus is active. Moisture is the main driver: heavy watering, rain and humidity. See brown patch in a lawn if your patches are round. UF/IFAS also says mild white grub damage leaves turf yellow and is hard to diagnose, while major damage leaves large areas of dead turf.
Checklist
What to check yourself, and Tampa's watering rules for new sod
Checks you can do, and what to leave alone
These checks need a hand trowel, a camera and a few minutes.
- The tug test. Tug a yellow piece: if it holds to the soil, keep watering; if it lifts with no new roots, ask us to look before you replace it.
- The sprinkler walk. Run each zone and watch for missed strips and soggy spots. Florida law requires every automatic lawn sprinkler system to have working technology that stops it when there is enough moisture, and a licensed contractor working on a system must test it and fix or add one.
- The soil push. UF/IFAS says that if you struggle to push a tool more than a few inches into the soil, the root zone is likely compacted, which leads to shallow roots and poor drainage.
- The bug edge. At the line between brown and green grass, look for tiny black-and-white adults or orange nymphs. UF/IFAS also describes vacuuming about 1 square foot of that edge and dumping it on white paper.
- The soil sample. UF/IFAS says to get a soil test through the county Extension office; the UF/IFAS Extension Soil Testing Laboratory tests samples.
Leave these alone while you sort out the cause. Do not fertilize before the 30 to 60 days are up, and not at all from June 1 to September 30. Do not mow before 3 to 4 weeks. Do not lay new sod over old grass or weeds. Do not water outside the hours Tampa allows, covered next.
Tampa watering rules for new sod
The City of Tampa Water Use Restrictions page (April 3, 2026 order) says new sod may not be watered between 4 a.m. and 8 p.m. The city points to the UF/IFAS 30-day establishment schedule, then normal days apply. Normal means once a week, on a day set by the last digit of the house number.
| Last digit of house number | Lawn watering day |
|---|---|
| 0 or 1 | Monday |
| 2 or 3 | Tuesday |
| 4 or 5 | Wednesday |
| 6 or 7 | Thursday |
| 8 or 9 | Friday |
Mixed and no-address properties water Friday. Lawn watering is allowed only from midnight to 4 a.m. or 8 p.m. to 11:59 p.m., once on your day, and never between 4 a.m. and 8 p.m. Properties of one acre or more may use both windows on their day. The regional one-day-a-week order runs until March 31, 2027 (Hillsborough County, September 2026). The district limits apply to everyone, including homes on private wells. Reclaimed water used for irrigation in Tampa is generally not subject to the restrictions.
Breaking the rules can bring fines up to $500 and a mandatory court appearance, and citations can be issued on first observance. Ask whoever laid your sod which schedule they set on the controller, and check it against the city's rules.
Cost
New sod dying: the fix, the cost and who to hire
What the fix involves
Find the cause first. Then remove the dead turf and fill with plugs, sprigs or sod. Where damage is extensive, UF/IFAS suggests replacing those areas with a different grass or another plant rather than patching. The Hillsborough County Extension office says to replace a lawn when 30% or more of it is weeds, bare spots or damage.
Before any new sod goes down, the ground needs the prep it may have missed the first time: old grass and weeds removed or killed, compacted soil tilled 6 to 8 inches deep, and the lawn graded 1% to 2% away from buildings or toward drains.
St. Augustinegrass is planted as sod or plugs, and UF/IFAS calls chinch bugs its hardest pest. Ask us which grass suits your yard's sun and water before you re-sod after chinch bug damage. Ask for a written start date and finish date with the quote.

What moves the price: the square footage, the grass type, whether old grass has to come out, and the grading or tilling before the sod. Labor for sod installation runs $37.50 to $77.50 an hour, or $0.55 to $1 per square foot (national range, 2026). For a Tampa number, ask for a written, itemized price after the crew walks your Tampa yard and measures it. Our landscaping cost guide lays out more national ranges.
Choosing who re-lays your sod
The Better Business Bureau says a company that quotes without seeing the yard cannot know what it needs, so get a price after an on-site look. The FTC says to compare bids for the same work and ask for an explanation if the estimates differ a lot, and that a written estimate should list the work, the materials, the completion date and the price. Ask how long new plants are guaranteed and what watering the guarantee expects. In Florida, a home contract over $2,500 must carry a lien warning: unpaid subcontractors or suppliers can claim against your property even if you paid in full, so ask for a written release of lien.
If the job includes fertilizer, Florida law says anyone applying commercial fertilizer to a Florida yard for pay must hold the state limited urban landscape fertilizer certification, and you can ask the applicator to show it. Ask who will apply any weed or pest treatment and which state licence they hold.
Questions about new sod turning yellow or brown
Is my brown sod dead?
Color alone will not tell you. Tug a yellow piece: if it holds to the soil, keep watering; if it lifts with no new roots, ask us to look before you replace it. Before you patch a dead area, look for what killed it, such as missed sprinkler spots, insects or disease.
When can I water new sod in Tampa?
Not between 4 a.m. and 8 p.m. The City of Tampa says new sod still may not be watered in that window, and points to the UF/IFAS 30-day establishment schedule, after which your normal watering day applies. Lawn watering is allowed from midnight to 4 a.m. or 8 p.m. to 11:59 p.m.
When can I mow and fertilize new sod?
The first mow waits 3 to 4 weeks, and fertilizer waits 30 to 60 days. In Tampa, nitrogen or phosphorus fertilizer may not be applied from June 1 to September 30.
Can I patch just the dead spots?
Find the cause first, then remove the dead turf and fill with plugs, sprigs or sod. If 30% or more of the lawn is weeds, bare spots or damage, the Hillsborough County Extension office says to replace the lawn instead.
What does it cost to replace sod in Tampa?
The table above shows national ranges. St. Augustine sod installed is $0.98 to $1.79 per square foot (national range, 2026), and old-grass removal adds $0.88 to $1.84 per square foot. Ask for a written, itemized price after the crew walks your Tampa yard and measures it.
