A better lawn.
A good lawn is less about products and more about a few habits done right: the correct grass for your climate, mown high, watered deeply but rarely, and fed in the right season. Get those and the lawn largely looks after itself, crowding out weeds and moss on its own. Here's the honest, no-gimmicks version.
❄️ Cool-season grasses
Best where winters are cold and summers mild - they grow most in spring and autumn. Sow in early autumn (or spring).
The all-rounder: deep roots make it the most drought- and heat-tolerant cool-season grass, it takes some shade, and it shrugs off foot traffic. The safe default for most cool and transition-zone lawns.
Germinates fast (great for quick repairs and overseeding), hard-wearing and glossy green - but shallow-rooted, so it needs more water and doesn't love deep shade or hard winters alone.
The classic lush, fine, self-repairing lawn - it spreads to knit bare patches shut. Slow to establish from seed and thirstier, so it's often mixed with fescue and rye rather than grown alone.
🔥 Warm-season grasses
Best where summers are hot - they thrive in the heat and go brown/dormant in winter. Sow or lay in late spring/early summer.
Loves heat and full sun, extremely wear- and drought-tolerant, and spreads aggressively to fill in - the go-to for hot, sunny lawns and sports turf. Needs sun (poor in shade) and goes brown/dormant in winter.
Dense, cushiony and slow-growing (less mowing), good heat and decent shade tolerance, and it crowds out weeds once established. Slow to fill in, and also browns off in winter.
The best warm-season grass for shade, with broad blue-green blades that make a lush carpet in hot, humid climates. Not very wear-tolerant and usually laid as sod, not seed.
A tough, native, very low-water, low-mow option for hot dry regions - soft and fine, but thin under heavy traffic and slow to establish.
Match the grass to your climate, sun and traffic with the grass type selector, then work out how much seed you need with the seed calculator. Check your climate with our hardiness zones.
Keeping it green - the four habits
Cut to the top of the grass's ideal range (roughly 6-9 cm for most lawns), and never remove more than a third of the blade at once. Tall grass shades out weeds and grows deeper roots; scalping does the opposite. Keep the blade sharp.
One good soak a week that wets the soil several centimetres down beats a daily sprinkle - it drives roots deep and drought-proofs the lawn. Water early morning to cut evaporation and disease. Most lawns want roughly 2-3 cm a week including rain.
Feed cool-season grass mainly in autumn (and lightly in spring); feed warm-season grass through its summer growth. Don't feed a dormant or drought-stressed lawn. Less, more often, beats one heavy hit that surges soft growth and disease.
Compacted soil and a thick thatch layer choke a lawn. Once a year, pull soil cores (aerate) to let air, water and roots move, and rake out excess thatch. Do it in the grass's main growing season so it recovers fast.
Common problems
Usually a symptom, not the disease - thin, mown-too-short or hungry grass lets weeds in. Mow higher, feed and overseed to thicken the turf, and most weeds get crowded out. Dig or spot-treat the persistent ones.
Moss moves in where grass struggles: shade, damp, compacted or acidic soil, and scalped turf. Fix the cause (improve drainage and light, aerate, raise the cut, lime acidic soil) rather than just killing the moss, which returns.
Could be drought, dog urine, dormancy (normal in summer for cool-season, winter for warm-season grass), a fungal disease, or fertiliser burn. Rule out the simple ones first - and remember dormant is not dead; it greens up when conditions ease.
Rake the area, loosen the surface, sow fresh seed of a matching type, keep it lightly moist until it germinates, and stay off it. Spring or early autumn is best for cool-season; late spring for warm-season.
⚠️ General guidance - the right grass, timing and mowing height depend on your exact climate and grass species, so treat local advice and the seed label as the final word. Keep fertilisers and any lawn treatments away from children, pets and ponds, and follow the label.
