Seasonal Lawn Maintenance Schedule: Spring Through Winter
Quick Answer
The jobs never change — mow, water, feed, clear debris, maintain the mower. What changes is how each one is done. Mowing height rises through summer and returns to normal in autumn. Watering peaks in July and stops by winter. Feeding is concentrated in autumn for cool-season lawns and summer for warm-season ones. Learn the shifts, not a list of dates.
Here is the whole year on one grid. Everything below is an explanation of a single row.
| Job | Spring | Summer | Autumn | Winter |
|---|---|---|---|---|
| Mowing | Start when growth resumes; normal height | Raise the deck; mow more often early, less in drought | Return to normal height; keep mowing until growth stops | None — do not cut short 'for winter' |
| Watering | Usually none; rainfall covers it | Peak — about 1 in/week, deep, early morning | Taper as growth slows | None, except warm-season desiccation in dry winters |
| Feeding | Cool: light, early-mid April. Warm: nothing until green-up | Cool: none. Warm: the main feeding window | Cool: the most important feeding. Warm: none | Neither — lime only if a soil test calls for it |
| Debris | Clear winter dead material before growth starts | Minimal | Keep leaves from packing down | Stay off frozen or waterlogged turf |
| Equipment | Check the irrigation system after winter | Sharpen the blade mid-season if mowing hard | Recondition the mower after the last cut | Sharpen and service — nobody is queuing at the shop |
The four transition moments people get wrong
- The first mow of spring— done too early on soft ground, or too short after winter growth
- Raising the deck for summer— forgotten until heat damage has already appeared
- The autumn feeding window— the most important weeks of the cool-season year, and the easiest to miss
- The last mow— cut extra short “for winter,” which is precisely backwards
A month-by-month calendar tells you what to do in September. This is the other axis — how each individual job changes as the year turns, and why. If you want the dated version, our annual lawn care checklist runs month by month with both grass families side by side.
Mowing Through the Year

Mowing is the job that changes most across the seasons, and the changes are the ones people most often skip.
Spring
Start mowing when growth genuinely resumes, not on a date. Cool-season lawns go straight back to their normal height. Before growth starts, a power rake or a low cut removes excess old growth and speeds soil warming and green-up.
Warm-season lawns get the one deliberate exception to every mowing rule on this site: a single low cut — around 1 inch for bermudagrass — just before green-up, bagging or raking off the dead winter material. Do it once, do not scalp, and raise the height afterwards.
Summer
Raise the deck. Missouri suggests increasing cool-season mowing height by half an inch to an inch if the stand is thin, with heights around 2.5 to 3 inches reducing scalping. Taller blades intercept more light exactly when the plant is under most stress, and they shade the soil surface.
Mowing frequency peaks in early summer and then falls away as growth slows in heat. Do not mow drought-stressed turf if you can avoid it, and avoid the hottest part of the day.
Autumn
Return to normal height and keep mowing until growth stops. This is often longer than people expect — cool-season grasses keep growing well past the point most people put the mower away.
Commonly believed
Cut the lawn extra short before winter so it does not mat down under snow.
What research shows
Missouri Extension advises mowing at regular heights until growth stops. Cutting short removes leaf surface the plant needs to build reserves going into winter and exposes the crown. The exception is the single low pre-green-up cut on dormant bermudagrass in late winter — a different job at a different time.
Winter
Nothing, in most regions. Stay off frozen or waterlogged turf, since traffic on frozen grass damages the crowns.
Watering Through the Year

| Season | What to do | Why |
|---|---|---|
| Spring | Usually nothing | Rainfall generally covers demand while growth is strong and temperatures are mild |
| Summer | About 1 inch per week including rain, deep, early morning | Peak demand. Water between roughly 4 and 10am to cut evaporation and let blades dry |
| Autumn | Taper as growth slows; soak a dormant lawn to restart autumn growth | Demand falls with temperature, but a dormant cool-season lawn needs water to resume |
| Winter | None for cool-season; occasional for warm-season in dry winters | Warm-season turf can suffer winter desiccation when dry spells precede hard freezes |
The summer decision is not a schedule but a judgement. Walk the lawn in the evening — if the blades in your footprints spring back, skip it. Our watering calculator converts a target depth into sprinkler run time, and one inch over 1,000 square feet is roughly 620 gallons.
Summer dormancy is a legitimate choice
Feeding Through the Year

This is where the two grass families diverge completely, and where following the wrong schedule does real damage rather than simply wasting money.
Cool-season
- Spring: light, early to mid April
- Stop soluble nitrogen after about 1 May
- Summer: nothing
- Autumn: the main feeding — the most important of the year
- Late autumn: a moderate application once cool days slow growth
Warm-season
- Late winter and early spring: nothing
- First feed only after full green-up
- Summer: the main window, with potassium
- Final nitrogen before mid-August
- Autumn: no nitrogen — potash only, before frost
Feeding the wrong family at the wrong time causes damage, not just waste
Autumn nitrogen on warm-season grass reduces winter hardiness; early spring nitrogen risks new growth being burned by a late frost.
Cool-season lawns have the opposite risk: soluble nitrogen after early May encourages foliar disease and soft growth that fails in summer heat. Identify your grass type before following any feeding schedule — our identification guide takes a few minutes.
Rates and product conversion are in our fertilizer calculator. Keep single applications at or below about 1 lb of nitrogen per 1,000 square feet, and apply lime only when a soil test calls for it.
Debris and Equipment Through the Year

Debris
- Spring: clear dead winter material before growth starts. It speeds soil warming and green-up.
- Summer: little to do beyond keeping clippings distributed rather than clumped.
- Autumn:the significant one. Do not let leaves pack down and smother the grass — a matted layer excludes light for weeks at exactly the time cool-season grass is doing its most valuable growing.
- Winter: keep traffic off frozen or waterlogged turf.
Equipment
The maintenance nobody schedules. Sharpen the blade in late winter, before the season starts — not in July when you notice torn tips. Check the irrigation system in spring after winter, running each zone and watching where the water actually lands. Recondition the mower after the final cut: clean oil, empty fuel tank, blade sharpened and ready.

The Four Transitions That Actually Matter

Most of the year runs itself. Four moments carry most of the consequence, and they are all transitions rather than steady states.
| Transition | What goes wrong | What to do instead |
|---|---|---|
| First mow of spring | Mowing too early on soft ground, or cutting too short after winter growth | Wait for genuine growth and firm ground; return to normal height, never removing more than a third |
| Raising the deck for summer | Left until heat damage is visible | Raise as stress begins — half an inch to an inch, and higher in shade |
| The autumn feeding window | Missed entirely, or done too late once growth has stopped | For cool-season lawns this is the year's most important application; put it in a calendar |
| The last mow | Cut extra short 'for winter' | Mow at regular height until growth stops, then stop |
Everything Above Depends on Which Grass You Have

The two families run almost opposite calendars. Cool-season grasses do their most valuable growing in spring and autumn and merely survive summer. Warm-season grasses run hardest through summer heat and shut down after frost.
That means the same month means different things. In September a cool-season lawn is receiving its most important feeding of the year while a warm-season lawn must receive no nitrogen at all. In the transition zone through the middle of the country, both families can survive but neither is fully comfortable — manage for whichever dominates rather than splitting the difference. Our transition zone guide covers the trade-offs.
Frequently Asked Questions
Setting Up Your Season
You do not need to memorise a calendar. You need to know which grass you have and what changes at each turn of the year.
- Identify your grass type, if you have not. Every row in the grid above splits on it.
- Set your mower to the correct height for the current season, and check it with a ruler rather than trusting the deck setting.
- Put the four transitions in a calendar, not the whole year. Those are the moments with consequences.
- Sharpen the blade now if you have not this year. It is the cheapest improvement available.
- For the dated version of all this, work from our month-by-month checklist — and for the recurring weekly routine, the weekly checklist.

Seasons here mean growth stages rather than calendar dates. Spring begins when your lawn resumes growth, which varies by several weeks with latitude and elevation, and the cool-season and warm-season schedules shift accordingly.
