The most common lawn problems are weeds, bare or thin patches, thatch build-up, fungal disease after wet weather, and pests such as lawn grubs. Most have simple first steps you can try, and identifying the cause first saves you treating the wrong thing.
Weeds
Weeds take over thin or stressed lawns. The best fix is prevention: mow at the right height, feed properly and fill bare patches. For existing weeds, remove or treat them while they are small, before they set seed.
Bare and thin patches
Thin spots usually come from shade, compaction, mowing too short, pests or spilled fuel and chemicals. Find the cause first, then loosen the soil, top-dress and let the grass spread or patch with turf. Re-seeding or re-turfing without fixing the cause just repeats the problem.
Thatch build-up
Thatch is a layer of dead stems and roots between the grass and the soil. A thin layer is fine, but a thick one blocks water and nutrients and harbours pests. Scarifying or dethatching in the growing season removes it.
Fungal disease
Warm, humid, wet weather is ideal for fungus. Look for brown or yellow circles and slimy or powdery grass. Reduce watering at night, improve air flow and drainage, mow with sharp blades and avoid heavy feeding while it is active.
Lawn grubs and pests
Chewed grass, birds digging at the lawn or patches that lift easily like loose carpet can point to grubs or other pests. Confirm what you are dealing with before you treat, and follow product labels carefully.

Frequently asked questions
How can I tell what is wrong with my lawn?
Look at the pattern: circles often suggest fungus, patches that lift suggest grubs, and thin areas in shade suggest light is the issue. If you are unsure, ask for a second opinion before treating.
Will a bare patch fill in by itself?
Sometimes, particularly with runner-forming grasses like buffalo and couch, but only if the cause has been fixed and the area gets enough sun and water.
Can I fix thatch myself?
Small areas can be done by hand with a dethatching rake. Larger lawns are easier with a scarifier.
Is it safe to treat lawn pests with chemicals?
Follow the label closely, keep children and pets off treated areas, and consider whether the damage is bad enough to justify treatment.
