Calendars & month-by-month lawn care

What to do this month — and why a calendar is a starting point, not the answer. Start with the lawn care calendar.

• seasonal · 8 minLawn care calendar UK: month by month (and when to ignore it)The month-by-month UK lawn care calendar, plus the three numbers that override it. Every year runs early or late; here is how to tell which one you are in.
• seasonal · 6 minWhy calendar-based lawn advice is wrongFeed in March, seed in September: advice built on an average year that never happens. What the grass responds to instead, and how to read it.

Renovation: scarifying, aerating, thatch and moss

The twice-a-year jobs that rescue a tired lawn — what each one does, and when the window is open. Start with the scarifying timing guide.

• seasonal · 8 minWhen to scarify a lawn in the UK (and when it's too late)Scarifying is a recovery gamble, not a calendar job: two UK windows, why autumn closes earlier than advice admits, and how to tell if your lawn will grow back.
• problems · 6 minHow to get rid of moss in a lawnMoss moves in where grass is weak. How to remove it the way the RHS advises, why it comes back, and when your lawn's recovery window is open.
• seasonal · 6 minHow to scarify a lawnWhat scarifying takes out of a lawn, the growth conditions that decide when to do it, and the raking method the RHS sets out for thatch and moss.

Feeding & fertiliser

When feed is taken up and when it is wasted, and why timing beats product choice. Start with the feeding windows guide.

• feeding · 7 minWhen to apply spring lawn feed in the UKMost spring lawn feed goes down too early, before the grass can use it. The signal that says your lawn is ready, and what happens to the nitrogen it cannot use.
• feeding · 6 minFeeding windows and why timing beats product choiceWhich fertiliser you buy matters far less than whether the grass is growing when you spread it. What governs uptake, and when feeding is wasted.

Weeds & lawn problems

What is actually wrong with the lawn, and what to do about it.

Seeding & overseeding

Sowing seed: what the soil needs to be doing, and how long each step really takes. Start with the overseeding timing guide.

• seeding · 6 minHow long does grass seed take to grow?Grass seed germinates in 5 to 10 days at 8°C and above, and up to four weeks for slow species. Soil temperature sets the clock, and here is how to read yours.
• seeding · 7 minOverseeding: the full timing guideOverseeding fails on timing far more often than technique. How to pick the window, and why autumn has a deadline most people count from the wrong end.
• seeding · 7 minWhat soil temperature grass seed actually germinates atGrass seed germinates on soil temperature, not the calendar. The real thresholds by species, how long each takes, and why sustained warmth matters.

Mowing timing

When to cut, when to wait, and how to read the week ahead.

• seasonal · 5 minWhen to stop mowing in autumnThere is no last-mow date. Grass grows until it stops, and the trigger is soil temperature and day length. How to judge the end of the season.
• mowing · 6 minWhat time can you legally mow in the UKThere is no UK law setting mowing hours. What exists is the statutory nuisance test, which weighs a persistent pattern rather than one early Sunday.
• mowing · 6 minWhy you shouldn't mow wet grassWet grass tears instead of cutting, clumps and smothers, spreads disease and lets a mower rut soft ground. Four problems, and what to do anyway.
• mowing · 5 minWhat time of day you should actually mowMid-morning to late afternoon, and the reason is dew. Why the first and last hours of the day are the worst, and how to find your own window.
• seasonal · 6 minWhen to cut grass after winterWhen to cut grass after winter: the trigger is growth plus a firm, dry lawn, not a calendar date. How high to cut the first time and how to check your soil.

Soil temperature & the model

How Mowdar measures what the grass actually feels, and why the forecast says what it says. Start with the soil temperature map.

• seeding · 6 minHow soil temperature is measured and modelledNobody has a probe in your lawn, so the figure is modelled. How that works, at what depth, how far to trust it, and how to check it yourself.

Weather stress: frost, drought and water

The weather that sets a lawn back, and the recovery it needs afterwards.

• problems · 5 minFrost and your lawn: what actually causes damageWalking on frosted grass ruptures the leaf cells and leaves footprints for weeks. The mechanism, and why grass frosts when the air is above zero.

New lawns & turf

Starting from nothing: turf or seed, and when each one works.

Grass species & seed choice

What is in the bag, and what that means for how the lawn behaves. Start with the cool vs warm season grasses guide.

• problems · 6 minCool-season vs warm-season grasses: which do you haveAlmost every UK lawn is cool-season; in the US it depends on latitude. How to tell them apart, and why it inverts every piece of timing advice.
