Lawn Problems (Symptom → Fix)
Most “my lawn is dying” issues come down to water coverage, mowing height, drainage or compaction, or a disease window. The articles below go deep on specific symptoms; this page is the fast overview and triage order.

Lawn Triage: Diagnostic Reference
Before buying expensive chemical treatments, identify the exact cause of the issue. Use this field guide to distinguish between pest infestations, pet damage, fungal infections, and simple cultural stress.
Pet Urine Spots
Lush, dark green ring of fast-growing grass surrounding a dead, brown center. Caused by concentrated nitrogen and salts in dog urine. Fix by flushing with water immediately, or raking out the dead center, topdressing, and patching.
Fall Armyworms (Pest)
Entire patches of Fescue or Bermuda turn brown and disappear in 48 hours, leaving a 'swept' look. Ragged, chewed leaf blades. Diagnosed by pouring a bucket of soapy water over a 3x3 ft patch—armyworms will wiggle to the surface within 60 seconds. Treat quickly with targeted insecticide.
White Grubs (Pest - Root Eaters)
Irregular brown patches that expand slowly in late summer. Grass feels spongy underfoot and can be easily peeled back from the dirt like a carpet because grubs have chewed off the root system entirely. Treat with preventative or curative grub control.
Fungal Diseases (e.g. Brown Patch)
Circular brown patches ranging from a few inches to feet wide, appearing during hot, humid summer nights. Fescue leaf blades show distinct tan lesions with dark borders. In morning dew, you may see cobweb-like mycelium threads. Adjust watering schedules to avoid night watering.
Most Common
Start with the symptom that matches what you see; each guide walks through likely causes and what to fix first.
Start Here (60 Seconds)
- Is it following the sprinkler pattern? Edges, corners, sunny strips usually mean coverage.
- Is the soil hard and water running off? Compaction or clay can block infiltration—pair with the screwdriver test below.
- Is it staying wet overnight? Long leaf-wetness windows raise disease pressure (especially in fescue).
- Did you cut too low recently? “Mower stress” can look like drought or fungus.
Screwdriver Test (Compaction Signal)
This is a quick field check—not a lab test. Use it to decide whether compaction deserves attention alongside watering and mowing fixes.
- Wet the soil lightly first (or test after rain). Bone-dry clay can feel artificially “rock hard.”
- Use a long screwdriver or sturdy probe and push straight down through the turf.
- Notice depth and ease. If healthy-looking turf resists shallow penetration while an unused corner slides deeper, compaction or shallow rooting may be limiting water uptake.
- Compare zones: paths, gate entries, and pet routes often compact faster than the rest of the yard.
- What it suggests: core aeration when grass is actively growing, fixing runoff-heavy watering, and building soil structure over time (organic matter / topdressing)—not a shortcut via heavy fertilizer.
Fast Sanity Checks
Quick links when you’re ruling out culture before you blame disease or buy products.
- Watering (Coverage-First) Dry corners and edges are the most common “false fungus” story.
- Watering Restrictions Prioritize new sod and hot strips when schedules tighten.
- Mowing Basics Scalping and heat stress mimic drought and patch diseases.
- Triangle Soils Clay + compaction → runoff and shallow roots.
- Weed Control Wrong product or hot-day sprays can look like random browning.
New Sod Issues
If the sod is brand new or seams look crispy, start with establishment physics (water contact + rooting)—not a fungus program. Each link opens the single guide you need; skim the headings first.
- New Sod Care (Day 0–14) Cadence, seam moisture, first mow window, and calendar reminders.
- Patch Repairs & Seams When a strip failed after install—edges, gaps, and quick fixes.
- Sod Tips & Tricks Short wins we repeat on Triangle deliveries.
- DIY Sod Installation Step-by-step when you’re laying it yourself.
