Seasonal Lawn Care
Zone 8 Spring Lawn Care Calendar: What to Do and When
Quick answer
Zone 8 is warm-season country: bermuda, zoysia, St. Augustine and centipede. Put pre-emergent down while soil at 2 inches holds 50 to 55 F, which comes early here, then wait for full green-up at 65 F soil before any nitrogen. Centipede gets the least of all, about 0.5 pound.
Zone 8 covers the Deep South from the Carolina coastal plain through Georgia, Alabama, Mississippi and Louisiana into east Texas, with winter lows of 10 to 20 F. Warm-season grasses run the show, and each one wants different handling: bermuda is cut low and fed hard, zoysia is cut low and fed lightly, St. Augustine is cut high, and centipede is barely fed at all. Treating all four the same is the fastest way to ruin one of them.
Spring is also the season with the tightest timing. The fertilizer calculator converts a bag analysis into pounds per 1,000 square feet, the grass seed calculator sizes seeding and plugging, and the lime calculator matters here because much of zone 8 sits on acidic sandy soil.

What does a zone 8 spring lawn care schedule look like?
Read soil temperature 2 to 4 inches deep in the morning. In zone 8 the 55 F mark arrives weeks earlier than most homeowners expect, and the pre-emergent window is missed more often than it is hit.
| Task | Trigger | Timing cue | Notes |
|---|---|---|---|
| Crabgrass pre-emergent | Soil 50 to 55 F at 2 in for 3 to 5 days | Late winter into early spring | Scotts Halts Crabgrass and Grassy Weed Preventer, 20.12 lb or sprayable Quali-Pro Prodiamine 65 WDG Pre-Emergent Herbicide, 5 lb |
| Soil test | Ground workable | Early spring | Sandy coastal soils here are often acidic and low in potassium |
| Lime or gypsum if the test calls for it | Ground not frozen | Early spring | Never lime centipede above pH 6.0; Old Castle Pro Pelleted Dolomitic Limestone, 50 lb |
| Scalp bermuda or zoysia | Just before green-up, soil near 60 F | Early to mid spring | Bag the debris; never scalp St. Augustine or centipede |
| Second pre-emergent application | 6 to 8 weeks after the first | Mid spring | Covers goosegrass, which germinates later at 60 to 65 F |
| Wait for full green-up | Soil steadily above 65 F | Mid spring | Patchy color is not green-up; the whole lawn must be growing |
| First nitrogen after green-up | Lawn fully green and mowed twice | Mid to late spring | Bermuda 0.5 to 1 lb, zoysia 0.5 lb, St. Augustine 0.5 lb, centipede 0.5 lb |
| Broadleaf weed control | Weeds growing, air 60 to 85 F | Mid spring | Confirm your grass is on the label; Ortho WeedClear Weed Killer for Lawns Concentrate, 1 gal |
| Core aerate | Grass growing hard, soil above 65 F | Late spring | Best done after two or three mows of active growth |
| Sod, plug or seed | Soil 65 to 70 F | Late spring | Bermuda 1 to 2 lb, zoysia 1 to 2 lb, centipede 0.25 to 0.5 lb per 1,000 sq ft |
St. Augustine cannot be grown from seed. It establishes from sod or plugs such as SodPods St. Augustine Seville Grass Plugs, 64 Count, which the listing rates at 144 sq ft per 64 plugs at 18 inch spacing once mature.
When should I fertilize my lawn in zone 8?
The first feeding waits for full green-up, then the total for the year is split across the growing season. These are annual totals with the spring share broken out.
| Grass | Nitrogen per year | First spring application | Spring notes |
|---|---|---|---|
| Bermudagrass | 2 to 5 lb per 1,000 sq ft | 0.5 to 1 lb after full green-up | The hungriest grass here; most nitrogen goes down in summer |
| Zoysiagrass | 1 to 3 lb per 1,000 sq ft | 0.5 lb after full green-up | Slowest to green up; over-feeding builds thatch |
| St. Augustinegrass | 2 to 4 lb per 1,000 sq ft | 0.5 lb after full green-up | Excess spring nitrogen feeds chinch bugs and gray leaf spot |
| Centipedegrass | 1 to 2 lb per 1,000 sq ft | 0.5 lb, once, later in spring | Excess nitrogen causes centipede decline; iron greens it instead |
| Tall fescue (upper zone 8 shade) | 2 to 4 lb per 1,000 sq ft | Up to 0.5 lb in early spring | Cool-season; fed mainly in fall |
No single application should exceed 1 lb of quickly available nitrogen per 1,000 sq ft. With a 32-0-3 product such as Lesco Basic Nutrition 32-0-3 Stabilized Nitrogen Fertilizer, 50 lb, 1 lb of nitrogen is about 3.1 lb of product.
Why should I wait for full green-up before feeding?
Because dormant grass cannot take up nitrogen. Applied early, it feeds winter weeds instead, wastes money, and encourages a flush of tender growth that a late cold snap can damage, which in a 10 to 20 F zone still happens. Full green-up means the whole lawn has turned and you have mowed it once or twice, not that the sunny half has color.
Green-up in zone 8 tracks soil temperature past about 65 F. Bermuda goes first, St. Augustine follows, and zoysia is usually last and slowest, which worries owners into feeding it early. If you want color before the grass is ready, apply iron rather than nitrogen, or use a low-nitrogen slow-release product such as Milorganite Slow-Release Nitrogen 6-4-0 Fertilizer, 5 lb Bag (4-Pack), which carries non-staining iron at 6 percent nitrogen. See how to read a fertilizer label.
How high should I mow each grass in zone 8?
Mowing height is the biggest single difference between these grasses. Bermuda is cut at 1 to 2 inches and zoysia at 1 to 2 inches, both low enough that a mower with a 1.5 inch minimum will not do it: the Honda HRX-BE 21 in. Battery Self-Propelled Mower drops to 0.75 inches and the EGO POWER+ LM2135SP 21 in. Select Cut Self-Propelled Mower Kit to 1 inch. Centipede sits at 1.5 to 2 inches. St. Augustine is the opposite and is cut at 3.5 to 4 inches for standard types, with dwarf varieties such as Seville held at 2 to 2.5 inches.
Cutting St. Augustine short is the single most common lawn mistake in zone 8. It has coarse, upright stolons and no ability to recover from scalping, and short mowing opens it to weeds and chinch bug damage. Never scalp St. Augustine or centipede in spring the way you would bermuda. Full profiles are on St. Augustinegrass, centipedegrass and bermudagrass, and every height is in the mowing height chart.
What gear does a zone 8 spring need?
An accurate spreader, a mower that reaches your grass's height, and a sprayer for weeds. Bigger lots should compare the best lawn spreaders.

Frequently asked questions
When should I fertilize my lawn in zone 8?
After full green-up, when soil is steadily above 65 F and you have mowed the lawn once or twice. Apply 0.5 to 1 pound of nitrogen per 1,000 square feet for bermuda, and about half a pound for zoysia, St. Augustine and centipede. Feeding dormant or half-green warm-season grass feeds winter weeds instead and can push tender growth into a late freeze.
Should I scalp my lawn in spring in zone 8?
Only bermuda and zoysia, and only just before green-up. Lowering the cut one or two notches removes brown winter leaf and warms the soil, and the clippings should be bagged. Never scalp St. Augustine or centipede: both grow from coarse surface runners, recover poorly from losing that much leaf area, and are left open to weeds and insects afterward.
How much lime does a zone 8 lawn need?
Only what a soil test calls for. Much of zone 8 is acidic sandy soil, where raising pH one full unit takes roughly 40 pounds of ground limestone per 1,000 square feet, against about 70 on loam and 100 on clay. Apply no more than 50 pounds per 1,000 square feet at a time, and never lime centipede above pH 6.0, which causes yellowing that is slow to reverse.
Can I use weed and feed on a St. Augustine lawn?
Check the label first, because many are not labeled for it. Combination products are timed for weeds, not for your grass, so the fertilizer often lands before green-up while the herbicide can injure St. Augustine, especially Floratam. Separating the two jobs, a pre-emergent at 50 to 55 F soil and a feeding after full green-up, gives better results on both counts.
