Whenever the lawn can be watered in, because St. Augustinegrass cannot be seeded at all. UF/IFAS Extension establishes it by vegetative propagation only, so in Sarasota the timing question is about irrigation, not a planting month.
Updated September 9, 2026
What the species allows
University of Florida IFAS Extension is explicit: St. Augustinegrass is established by vegetative propagation only, which includes sod, plugs or sprigs. There is no seeding route. That single fact reshapes the question most people are asking — a bare patch here is closed by laying material rather than sowing it, and Sarasota Greenscapes plans the work around irrigation rather than around a seeding month.
| Factor | Published value |
|---|---|
| Establishment method | Vegetative only — sod, plugs or sprigs |
| Seeding | Not possible for this species |
| Standard cultivars | BitterBlue, Classic, Floratam |
| Mowing height | 3.5 to 4 inches, rotary mower |
| Maximum removed per mowing | No more than one third of the leaf blades |
| Water per irrigation application | One-half to three-quarters inch |
| Deciding factor for cultivar | Shade, then salt exposure and traffic |
Why this grass dominates here
UF/IFAS describes St. Augustinegrass as producing a green to blue-green dense turf that is well adapted to most soils and climatic regions in Florida, with relatively good salt tolerance and, in certain cultivars, better shade tolerance than other warm-season grass species. On a coast with sea air, sandy soils and mature tree canopy, all three attributes count, and the salt tolerance is the one that matters most on coastal ground.
Timing is set by the water shortage order, not the season
The real constraint on when a lawn goes in is how often it can be watered once it does. Sarasota County sits under a Modified Phase III “Extreme” Water Shortage order, which is a once-a-week irrigation regime. Sod that dries before it roots does not recover well, so establishment under a weekly schedule is planned rather than improvised — and confirming the current restriction stage before the pallet arrives is part of the job.
Choose the cultivar for the site, not the catalogue
Standard cultivars such as BitterBlue, Classic and Floratam differ meaningfully in their tolerances, and shade is usually the deciding factor. Certain cultivars handle it noticeably better than others, which matters under live oaks or on the north side of a house. Salt exposure and traffic are the other considerations. Choosing a cultivar for a sunny open lawn and laying it under heavy canopy is a common and expensive mistake.
Salt tolerance is the attribute that separates this species from the alternatives on coastal ground, and it is the reason the choice rarely opens up here. A lawn within reach of sea air is working against a condition most warm-season grasses handle worse, so the cultivar decision is made against the site’s exposure before it is made against appearance.
The bed decides the result more than the date does
Existing grass, weeds and debris come out first, because laying sod over existing turf produces poor root contact and an uneven surface. The ground is graded for drainage away from the house and to remove low spots that would hold water and scalp under a mower. Rolls are laid tight with staggered seams and then rolled, because air gaps under sod are a leading cause of patchy establishment.
Sandy soil changes what establishment watering means
On the sandy soils common here the concern is less compaction than moisture retention, which makes establishment watering more demanding rather than less. UF/IFAS gives the application rate as one-half to three-quarters of an inch per irrigation. On a once-a-week allowance that is the figure to hit properly rather than approximate, since there is no second attempt until the next permitted day.
Mow it high once it takes
St. Augustinegrass is mown higher than most lawn grasses, and cutting it short is a common way to weaken a lawn that established fine. UF/IFAS gives 3.5 to 4 inches with a rotary mower for the standard cultivars, removing no more than one third of the leaf blades at a time. That one-third rule sets mowing frequency rather than the calendar: a lawn held at 4 inches is mown before it passes about 6 inches.
The bed sequence, in order
Removal and clearing first: existing grass, weeds and debris come out. Then grading, for drainage away from the house and to take out the low spots that hold water and scalp under a mower — a real consideration in a region that takes intense wet-season rainfall. Then soil preparation, so roots make immediate contact and can move down into the profile. Then laying, with rolls tight, seams staggered, cut cleanly at edges and around obstacles, and pegged on slopes where needed. Then rolling, to press roots into firm contact with the soil beneath. Then the first watering, thoroughly and immediately, because sod that dries before rooting does not recover well. On a once-a-week allowance that first watering carries more weight than it would anywhere else.
Sarasota planting questions
When is the best time to plant grass in Sarasota?
There is no seeding season, because St. Augustinegrass cannot be seeded. It is laid as sod, plugs or sprigs, and the timing question is whether the new lawn can be watered in under the current restriction stage.
Can I seed a St. Augustine lawn in Sarasota?
No. UF/IFAS Extension states St. Augustinegrass is established by vegetative propagation only — sod, plugs or sprigs. A bare patch is closed by laying material rather than sowing it.
How often can I water new sod in Sarasota?
Sarasota County has been under a Modified Phase III “Extreme” Water Shortage order, a once-a-week irrigation regime. Confirm the current stage and any new landscape allowance with the water authority before the sod is delivered.
Which St. Augustine cultivar should I use?
Shade is usually the deciding factor. BitterBlue, Classic and Floratam differ meaningfully in shade, salt and traffic tolerance, so the cultivar follows the site rather than the catalogue.
