How to Winterize a Sprinkler System: 80 PSI, or 50
Colorado State puts blow-out pressure at 40 to 80 psi — 80 max for rigid PVC, 50 for polyethylene. And two backflow devices must never see compressed air at all.

Lawn Watering Restrictions: Keeping Grass Alive
Your city assigns the days and bans the hours. How to hit a weekly inch in two legal windows, and why cycle-and-soak is the trick.

Best Lawn Aerator: Two of the Three Options Make It Worse
MSU: solid-tine aeration pushes soil sideways and increases compaction. That rules out spike rollers and aerator sandals. Hollow tines or nothing.

Best Robot Mower for Large Yards: Width Beats Capacity
A 2-acre rating on a 9.4-inch deck is achieved with hours, not throughput. Cutting width varies 2.4× across these machines and decides whether an acre gets finished.
Lawn Care Guides
Best Robot Mower for Small Yards: The Weakest Tier
A quarter acre is the size extension recommends these for — and the price bracket where our three ratings are the lowest of any we have given. Both things are true.
Lawn Care Guides
Robot Mower for Slopes: The Boundary Number Is the Real One
A 45% slope rating can collapse to 15% at the lawn's edge — and the edge is where a sloped yard is steepest. Read both numbers before buying.

Robot Mower vs Lawn Service: It Replaces the Mow, Not the Visit
A robot mower does not edge, trim or blow. Compare it against the mowing line only — then decide who does the edges, because someone still has to.
Lawn Care Guides
Robot Mower Winter Storage: The Standard Advice Is Wrong
The float-charger advice everyone repeats was written for lead-acid batteries. A robot mower has a lithium pack, and the manual is the number that governs.

Robot Mower Without Perimeter Wire: They All Are Now
Every mower we track is wire-free. The real question is what happens when the satellite signal degrades — and on two of them, nothing does.

Dormant Seeding: The Backup Window After You Missed Fall
Purdue's data: dormant seeding beats spring and trails September only slightly. The rule is cold enough not to germinate — Thanksgiving through March, not October.

Lawn Recovery After Flooding: The Clock Starts Underwater
How long turf survives underwater, why the damage shows up days later, the 1-inch silt rule, and the survival percentage at which replanting beats rescuing.

Lawn Ruts After Storm Cleanup: What Repairs, What Doesn't
Shallow ruts take a ¼-inch topdressing; deep subsoil compaction from heavy equipment on saturated ground is, in Penn State's words, practically permanent.

Mulching Leaves Into the Lawn: MSU's Case Against the Rake
MSU research links mowed-in leaves to less fertilizer and, after three years, a near-100% drop in dandelions and crabgrass. The limits: thin, dry, and visible grass.

Saltwater Flooded Lawn: Flush It Before You Feed It
Storm surge leaves sodium behind, and it wilts grass in wet soil. The flush volumes, the gypsum rate, and the soils where gypsum is the wrong answer.

Waterlogged Lawn: Test It Before You Fix It
Water standing after every rain has four possible causes and they need different fixes. A 15-minute hole test tells you which one you have before you spend money.

When to Stop Mowing the Lawn: Watch 50°F, Not the Calendar
Cool-season grass stops growing when daytime highs stay below 50°F — that's the last-mow trigger. Too tall into winter invites disease; scalping is worse.

After Hydroseeding: The 30 Days That Decide It
What to do after hydroseeding: the seed sits on the soil rather than in it, so drying is the failure mode. MSU's regime is light water two or three times a day.
Lawn Care Guides
What Is Hydroseeding? And When It Actually Wins
What is hydroseeding: seed, water, fertilizer and mulch sprayed as a slurry. Penn State rates it most efficient for large areas or steep slopes — not small lawns.

Grass Seed vs Sod: The Instant Lawn Has a Catch
Penn State: new sod needs daily water for up to 4 weeks before it roots. It also picks your grass species for you — in Pennsylvania that usually means bluegrass.

How to Level a Bumpy Lawn Without Ruining the Soil
Clemson: sand should only topdress a lawn when the native soil is sandy. On clay it does the opposite of what you want — and half an inch is the pass limit.

How to Make Grass Thicker: Can Yours Even Spread?
Penn State rates tall fescue's recovery as only fair — it is bunch-type and does not creep. Half the thickening advice online assumes a grass that spreads.

Is My Grass Dead or Dormant? Check the Crown
Iowa State: most lawns survive 4 to 6 weeks dormant. Illinois warns that breaking dormancy drains reserves — so half-watering a brown lawn is the worst choice.

Winter Lawn Care: The Damage Happens in February
Penn State: crown hydration is the most common and destructive winter injury, and it happens in late winter after thawing and freezing — not in the deep cold.

Do I Need a Food Plot? Arkansas Extension Says Maybe Not
Plots rarely sustain a population, you can destroy good native habitat replacing it, and land management matters more. Then: 1 acre per 40, and rotate.
Lawn Care Guides
Food Plot Seedbed Preparation: Lime Three Months Early
Lime needs two to three months before planting. Clover goes no deeper than ¼–½ inch. Legume seed must be inoculated. Most plots fail on these three.

How to Dethatch a Lawn — And Why Extension Says Don't
Under half an inch, thatch helps. The roots live in it, so the machine rips plants out. Illinois names core aeration and topdressing as the fix instead.
Lawn Care Guides
How to Kill a Lawn Before Reseeding — Or Not Kill It
Penn State decides this with two measurements, not a feeling: how much of the lawn is desirable grass, and how deep the thatch is. Under 50% is the kill-off line.

Lawn Striping: The Conflict Nobody Selling a Kit Mentions
Stripes need the same mowing line every week. MSU says vary the direction to reduce wear. Both are true, and a striping roller adds the weight Purdue warns about.

Microclover Lawn Pros and Cons: The Permanent Trade-Off
Microclover fixes its own nitrogen and feeds bees. It also ends whole-lawn broadleaf spraying forever, and dies back in winter. Extension seeding rates inside.

Are Robot Mowers Worth It? Which Lawns They Fail On
UF/IFAS Extension names the lawns robotic mowers suit and the ones they don't. Irrigation heads, lightning, fire ants and theft are on the official list.

Do Robot Mowers Improve Lawn Health? What Research Shows
Daily micro-clipping is a different practice from a weekly cut. Extension research documents denser turf and less weed cover — plus one weed that gets worse.

Grass Paint for Lawns: The Honest Case for Turf Colorant
Painting dormant bermuda sounds like cheating. NC State's guidance suggests it can leave the lawn healthier than overseeding, because nothing competes in spring.

Salt Tolerant Grass Seed: Coastal Spray and Road Salt
Spray reaches 1,000 feet; soil salt sits within 30. Species choice fixes more than any product, and the usual gypsum advice has a drainage catch.

Summer Lawn Care: What Helps and What Hurts
Summer lawn care inverts by grass type: feeding a warm-season lawn is routine; feeding a cool-season lawn is the classic mistake.

Dog Urine Lawn Damage: The Real Cause and the Fix
Dog urine burns lawns in sharp circles ringed dark green. The ring is nitrogen — the dead centre is not: NC State points at lactic acid. That changes the fix.

Fall Lawn Care: What to Do, and in What Order
Fall lawn care is the one season when doing more genuinely pays — for cool-season grass. On a warm-season lawn, autumn is mostly about stopping.

How to Aerate a Lawn: Spike Tools Make It Worse
How to aerate a lawn, and when not to: spike tools compact the soil they punch through, core aeration pulls plugs out, and most lawns need it rarely.

How to Fix Bare Spots in a Lawn — Or Leave Them
A bare spot smaller than your fist closes on its own. The bigger ones are a symptom — and the shape of the spot tells you which cause to fix first.

Lawn Mowing Height: Your Deck Setting Is Lying
Your deck setting is not your lawn mowing height — measure it once and most people find they cut lower than they think. The real number by species.

Should You Bag Grass Clippings? It Costs Nitrogen
Bagging grass clippings throws away up to a quarter of your lawn's nitrogen — and clippings do not cause thatch. The three times bagging is still right.

Spring Lawn Care: Do Less, and Do It Later
Most spring lawn damage is done in March by people being helpful. Spring lawn care runs on soil temperature, not the calendar — and the order matters.

When to Overseed Your Lawn — and When Not to Bother
When to overseed: late summer beats spring for cool-season lawns, most warm-season lawns should not be overseeded at all — and pre-emergent blocks your seed.
