Sod installation can put Floratam in partial shade. It cannot put a lawn where the sun never hits the ground. That distinction saves people from paying for a second dead yard. If the space under the canopy should be plants instead of grass, that work is landscaping, designed for the light that is actually there.
St. Augustine, and Floratam in particular, is the grass we recommend when a yard gets sun part of the day and humidity the rest of the time. Bahia wants open ground. Zoysia wants sun and a tighter cut. None of the three is a deep-shade turf. The comparison is the grass types guide.
Partial shade versus a dark yard
Partial shade is a wall that gets morning sun, or a lawn with trees at the edge and open sky in the middle. Floratam can hold there if it is cut at 3.5 to 4 inches and it gets water. The tall cut matters more in shade than it does in full sun, because a scalped lawn has even less leaf to live on when the light is already limited.
Deep shade is the ground under a mature oak that is dark at noon. Grass thins, weeds that tolerate shade move in, and new sod follows the old sod. Laying Floratam there does not change the light. Raising the canopy, a crown raise that takes low limbs off the roof and lets light in, is sometimes part of the answer, and it is tree work, quoted on its own. It is not a promise that grass will return the week the limbs come off.
How to tell which kind of shade you have
Stand in the spot at noon, not at 8 a.m. If you have a hard shadow and the ground is bare while the sunny front is fine, that is deep shade, and Floratam is the wrong purchase. If the shadow moves off by late morning and the grass is only thin because it was cut short, that is partial shade, and the deck at 3.5 to 4 inches plus water is the first experiment. A photo at noon is the one to send. A photo at sunset makes every yard look hopeless. The drip line of a mature oak is the usual border. Inside it, plan on a bed. Outside it, grass can be the lawn. We will not draw that line from a satellite picture.
Raising the crown can move the line. Taking low limbs off a roof and opening a window in the canopy lets more light through, and it is a tree-trim quote, not a promise that sod will survive what remains. We will not top the oak to force a lawn. Coontie, mulch, and a rock strip at the slab will look better under that tree in September than a third try at Floratam. If part of the yard is sun and part is this, the quote can be both: sod where the noon photo is bright, a bed where it is not. One crew, one grade, and no story that the grass "just needs time" in the dark.
A bed under an oak is not a consolation prize. It is the planting that matches the light: coontie that stays low, mulch on the roots, rock only where the slab needs a dry strip, and no Floratam forced into a photo background. If you still want grass, we will show you the noon line and sod only the bright side. The shady side gets the bed on the same visit so you are not hiring a second crew to undo the first. Crown raising, if a limb is also on the roof, stays a tree quote. It can help the light. It does not replace the noon test, and it does not come with a promise that the lawn fills back in by itself. If the bright side is large enough to be a lawn and the dark side is a bed, both can be on one quote so the grade is cut once. We will not sell the dark side as grass to keep the ticket simple. Partial shade can stay lawn. All-day shade should not be sold as sod.
When the answer is a bed
If the area is a foundation, a side yard, or the drip line of an oak, stop trying to mow it. A bed uses plants that are already on our landscape list for this climate: coontie, which stays compact and does not climb into gutters, croton and viburnum where they still get enough light to color up, and a sabal palm only where a trunk has room and the fronds will not live in the roof. Mulch around those plants holds moisture. Rock belongs near the slab, not piled against bark. The foundation planting guide and the rock versus mulch guide split those materials.
A bed is also the honest quote. Sod at $0.85–$1.75 per square foot looks cheaper until it dies and you buy it twice. A single bed refresh is often $400–$1,200. The walk tells you which number you are actually choosing. We will say when the grass is the wrong tool.
Bring a photo taken at midday, not just in the morning. If you want grass where the light supports it, and a bed where it does not, that is one visit. The grass half is sod installation.
Frequently asked
Will Floratam grow in shade?
It handles partial shade. It is not a deep-shade grass. A yard that is dark under an oak all day will not hold it.
What should I plant instead of grass in deep shade?
A bed. Coontie is the foundation plant we use because it stays put. The plant list is matched to the light on that spot during the landscape walk.
Does cutting the lawn shorter help it in the shade?
No. St. Augustine wants 3.5 to 4 inches. Scalping it removes the leaf it needs, and shade makes that worse.
Can you raise the tree and sod underneath?
Crown raising is a separate tree quote. It can let more light in. It is not a guarantee that sod will survive under what is left of the canopy.
