Lawn care in October
There is no single answer for October, and that is the useful part: a warm-season lawn and a cool-season lawn want opposite things from the same month. Find your grass in the grid below and work from its own October page.
Warm-season lawns in October
In October, warm-season lawns run from slowing down to going dormant depending on where you are — that is Bermuda, Zoysia, St. Augustine, Centipede and Bahia. Soil temperature across the zones they grow in sits around 52–72°F at 4-inch depth. The work most of them share this month: fall pre-emergent for winter weeds; last mow before dormancy; mow on a routine.
What most warm-season lawns can skip
- Nitrogen — work back from your own first-frost date, not the calendar. The cutoff is about six weeks before your average first frost, which is late October on the upper Gulf and in north Florida, and later again further south. UF/IFAS puts the last feed in the middle or end of September in north Florida and early October in central Florida; in south Florida, which rarely freezes, it can be applied year-round as needed.
- Aeration — the growing season left is too short to close the holes before dormancy.
Cool-season lawns in October
In October, cool-season lawns run from in peak growth to slowing down depending on where you are — that is Tall Fescue, Kentucky Bluegrass, Perennial Ryegrass and Bentgrass. Soil temperature across the zones they grow in sits around 52–60°F at 4-inch depth. The work most of them share this month: core aerate — last chance this year; keep leaves off the lawn; lime, if the soil test called for it.
What most cool-season lawns can skip
- Overseeding — October is late. Seed now establishes thin and winter-kills; wait for next September.
Every grass type in October, by region
A blank cell means the grass is not grown in that zone — absent on purpose, not a gap. There is no tall fescue schedule for Miami and there should not be one.

October lawn care: common questions
Should I fertilize my lawn in October?
It depends on your grass, and the answer is not "a little of both". Tall Fescue, Kentucky Bluegrass, Perennial Ryegrass and Bentgrass carry a nitrogen application somewhere in October; Bermuda, Zoysia, St. Augustine, Centipede and Bahia do not. The zone matters as much as the grass, so open your grass's October page rather than feeding on the calendar.
Do I still need to mow in October?
Yes — every grass we schedule is still being mown somewhere in October, though the height and the interval differ by grass and by zone.
Which grass types are dormant in October?
None of the nine, in any zone. Several are going dormant in October — slowing, losing colour and heading for it — but none has stopped. A lawn that has gone brown and is not yet dormant is worth a second look: brown in a month the schedule says is still growing is usually drought or disease, not the season.
What should I not do in October?
Warm-season lawns: Nitrogen — work back from your own first-frost date, not the calendar. The cutoff is about six weeks before your average first frost, which is late October on the upper Gulf and in north Florida, and later again further south. UF/IFAS puts the last feed in the middle or end of September in north Florida and early October in central Florida; in south Florida, which rarely freezes, it can be applied year-round as needed. Aeration — the growing season left is too short to close the holes before dormancy. Cool-season lawns: Overseeding — October is late. Seed now establishes thin and winter-kills; wait for next September.
