Lawn Care Basics by Season

Lawn advice usually arrives as a national calendar, and the grass in your yard has never seen it. A lawn in Minnesota and a lawn in Florida are different plants, living in different soil, on different schedules. The most useful thing you can do before following any seasonal plan, including this one, is figure out what you are growing and how your local climate treats it.

With that in mind, here is a season-by-season framework you can adjust to your own yard.

Start with your grass and your soil

Most lawns fall into two broad groups. Cool-season grasses, such as tall fescue, Kentucky bluegrass and perennial ryegrass, grow hardest in spring and fall and slow down in summer heat. Warm-season grasses, such as Bermuda, zoysia, St. Augustine and centipede, grow hardest in summer and go dormant and brown in winter. Some regions, often called the transition zone, grow a mix, which makes timing trickier.

If you don't know your grass type, a sample taken to a garden center or your local cooperative extension office can usually settle it. Extension offices, typically connected to a state university, are also where you can get an affordable soil test. A soil test tells you pH and nutrient levels, so you are feeding the lawn what it actually needs instead of guessing.

Notice how much sun each part of the yard gets, too. Grass that struggles under a big shade tree may never thrive there, and a shade-tolerant seed mix or a mulched bed can be a more realistic answer than reseeding the same bare patch every year.

Spring: wake it up gently

As the yard dries out, rake up leftover leaves, sticks and matted patches so light and air can reach the soil. Before the first mow, get the mower ready: sharpen or replace the blade, change the oil if it has an engine, and check the air filter. A dull blade tears grass instead of cutting it, and the ragged tips brown and invite disease.

Wait until the grass is actively growing and the ground is firm before mowing. Soggy soil compacts easily, so hold off on heavy foot traffic, mowing or aerating until you no longer leave footprints. If you use a pre-emergent product for crabgrass, timing is tied to soil temperature, not a date on the calendar, so check your extension office's guidance for your area. Fertilizer timing also differs: many cool-season lawns get a light feeding in spring, while warm-season lawns are usually fed once they have fully greened up. Read every product label and follow it exactly.

Summer: mow high and water deep

Summer is about helping grass cope with heat. Raise the mower deck. Taller grass shades the soil, holds moisture better and crowds out weeds. A common guideline is to never cut off more than a third of the blade at one time, which may mean mowing more often during growth spurts. Leave the clippings on the lawn, where they break down and return nutrients to the soil. Mow when the grass is dry, keep kids and pets inside while the mower runs, and wear sturdy shoes and eye protection.

Water deeply and less often rather than a little every day, since deep watering encourages deeper roots. Early morning is usually the smartest window, because less water evaporates and the grass dries before night. Many cities and water utilities set watering days or limits in summer, so check your local rules. Cool-season lawns may go dormant and tan in a long dry spell. That's a survival mode, not necessarily death, and they usually green up again when cooler, wetter weather returns.

Watch for irregular brown patches that pull up like loose carpet, which can point to grubs. Before treating anything, get the problem identified, either through your extension office or a licensed lawn care provider.

Fall: the season that pays you back

For cool-season lawns, fall is the main event. Warm soil and cool air create good conditions for roots and new seed. This is the usual time to core aerate compacted soil, overseed thin areas, and apply fertilizer if your soil test calls for it. Keep new seed consistently moist until it's established.

Leaves shouldn't be left in thick mats, which smother grass. A light layer can be mulched with the mower. Heavier drops need raking or collecting, and many cities have their own rules and schedules for leaf pickup. Warm-season lawns, by contrast, are slowing down in fall, so heavy feeding late in the season usually isn't recommended. Keep mowing as long as the grass grows. If you have a sprinkler system, have it drained or blown out before the first hard freeze, a job many homeowners hand off to an irrigation pro.

Winter: rest, protect and plan

Try to stay off frosted or frozen grass, since footsteps can crush the blades and leave brown tracks. Along driveways and walks, shovel before you salt and use deicers sparingly, since heavy salt can damage turf and plants near the edges. Big piles of shoveled or plowed snow can smother the grass underneath, so spread them out where you can. As snow melts, you may spot matted gray or pinkish patches, often a fungus called snow mold, and a light raking to help them dry out is usually enough. Once mowing season ends, prepare the mower for storage according to its manual, which usually covers fuel, the battery and cleaning the deck. Winter is also a good time to sketch out the yard, note problem spots, and plan next year's soil test.

Chemicals, local rules and hiring help

Fertilizer and pesticide rules vary by state and city. Some areas restrict fertilizer near water or during certain months, limit phosphorus, or require posted signs after an application. Applying pesticides for hire generally requires a state license. If you do use lawn products yourself, store them in their original containers, out of reach of children and pets. If you're dealing with a pest or weed problem you can't identify, or you'd rather not handle chemicals at all, a licensed lawn care company is a sensible call.

Before you hire one, ask:

• Are you licensed for pesticide application in this state, and are you insured?
• Will you do a soil test before recommending products?
• Which products will you use, and how long should kids and pets stay off the lawn?
• How do you adjust the plan for my grass type and local watering rules?
• What does each visit include, and how do I pause or cancel service?
