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.
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.
- How 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.
- How 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.
Seeding & overseeding
Sowing seed: what the soil needs to be doing, and how long each step really takes. Start with the overseeding timing guide.
- How 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.
- Overseeding: 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.
- What 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.
- When 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.
- Why 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.
- What 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.
- When 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.
Weather stress: frost, drought and water
The weather that sets a lawn back, and the recovery it needs afterwards.
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.
