A brown patch on a Winter Garden or Horizon West street view can trigger an HOA notice faster than a homeowner expects. The useful first move is not panic, and it is not assuming the whole irrigation system has failed. Separate coverage (did water land where it should?) from soil and plant problems (compaction, thatch, insects, disease, shade, new sod) before you book the wrong trade.
Orlando West Irrigation is a matching service. We connect a homeowner with a local irrigation tech; we do not climb into valve boxes, mow lawns, or diagnose turf disease from this page. What we can do is help you describe the problem clearly, so the right person shows up.
Why do dry zones show up so fast in Central Florida?
Central Florida gets plenty of rain on paper. The Florida Climate Center’s 1991–2020 normals for Orlando show about 51 inches a year, but most of it falls from June through September, and the late fall and winter months are much drier, with November averaging under 2 inches. UF/IFAS Extension points out the other half of the problem: Florida’s sandy soils hold very little water, so lawns are often overwatered in the wet season and can go short during the dry season.
That combination means a zone that quietly stops working in October or November can show brown edges within a couple of weeks. In summer, afternoon storms may mask a broken head entirely, until the rain stops and the patch appears. Water-shortage orders make it sharper still: with fewer allowed days, a zone that misses one run may wait several days for the next. Check your current days on our watering days and restrictions page, which links to the official SJRWMD source.
How do I run a simple dry-zone test?
If you can safely run the controller, watch each zone that touches the dry patch. SJRWMD’s rules allow systems to be run briefly for maintenance and repair checks, so a short test is normally fine. Ask four questions:
- Does that zone actually start when you trigger it from the controller?
- Do the heads pop up and spray, or do you hear water with no coverage?
- Is a head tilted, buried in thatch, clogged, or blocked by a shrub that grew over the summer?
- Does the spray reach the dry edge, or does it fall short on one side of an arc that used to reach the sidewalk?
Write the answers down. Photos of the patch and of a running head next to it help a matched tech triage without guessing on the first call. If the zone never starts at all, the problem may be a valve or the controller rather than the heads; jump to controller and timer and our head vs valve vs controller guide.
Can I check coverage without special tools?
Yes, roughly. Irrigation auditors use “catch can” tests to measure how evenly a zone applies water, and UF/IFAS describes them in its review of residential irrigation maintenance problems. A homeowner version is simple: set a few identical straight-sided containers across the green area and the brown area, run the zone for a set time, and compare the depth. If the cans in the brown patch are nearly empty while the green side has water, coverage is your problem. If the depths are similar and the patch is still brown, look harder at the turf itself.
What does an irrigation-caused dry zone look like?
Irrigation is the likely cause when:
- Neighboring zones look fine but one zone stays brown after a normal schedule.
- The brown shape follows a spray arc, a curb strip, or the far edge of a head’s throw.
- You see misting, puddles at a fitting, or a soggy strip along a line while turf beyond it stays dry.
- A head is broken, missing, stuck down, or no longer pops above the grass.
- Manual runs work for other zones but not this one.
- A rain sensor or schedule change coincided with the patch appearing.
UF/IFAS Extension’s irrigation system maintenance guidance lists the same culprits: clogged nozzles cause dry spots, tilted heads throw more water to one side, and heads often need raising as turf grows. That is sprinkler repair or irrigation maintenance territory.
When is it soil, insects, or disease instead?
West Orange and south Lake lawns are mostly St. Augustinegrass on sandy soil, with summer heat and HOA expectations for even color. UF/IFAS’s guide to St. Augustinegrass for Florida Lawns names southern chinch bugs as its major insect pest and lists diseases such as gray leaf spot, large patch, and take-all root rot. Its companion guide on proper irrigation techniques notes that large patch is most commonly seen from November to May.
Clues that point away from irrigation:
- The brown shape follows a tree canopy or a shaded side of the house rather than spray patterns.
- Rings or irregular patches cross zone boundaries.
- Every head on the zone sprayed evenly in your test and the catch cans filled evenly.
- The patch is in new sod that was laid recently and never rooted well.
- The grass looks scalped or torn, which can point to mowing height or dull blades.
Overwatering causes problems too. UF/IFAS’s Watering Your Florida Lawn warns that overwatering increases disease susceptibility and thatch, shortens roots, and encourages weeds such as dollarweed and sedges. A soggy, yellowing patch next to a leaking head is still an irrigation problem, just the opposite one.
If the evidence points to turf health rather than water delivery, soft-refer to Lawn Care rather than forcing an irrigation request. Ambiguous “yard looks dead” notes should say what you already checked: did the zone run, did heads spray, and does the brown shape follow a spray pattern or a tree?
How do I tell drought stress from a dead patch?
UF/IFAS describes drought-stressed St. Augustinegrass as having folded or wilted leaf blades, a blue-gray tint, and footprints that stay visible after you walk on it. Those are signs the grass needs water and is not getting it, which, if the rest of the lawn looks fine, usually means that zone is not delivering. A patch that is straw-colored, thinning, and pulls up easily may have been stressed for longer, or may have an insect or disease problem layered on top.
How should I handle the HOA timing?
If you have a written notice, put its date and any photo requirement in the form notes. Practical urgency helps a matched tech prioritize. We will not invent fines or threaten homeowners on this site. See the HOA dry zones page for what to send, and keep before-and-after photos for your reply to the board.
What does matching mean here?
We match residential irrigation requests in Winter Garden, Horizon West, Hamlin, Waterleigh, Windermere, Ocoee, Oakland, Stoneybrook West, Clermont, and Minneola. The tech confirms scope, price, and schedule. We do not publish a shop address, phone number, license number, or reviews. Local guides: Winter Garden, Horizon West, and Clermont.
Vacant home watch is SafeNest, not this site. Soft Wash, Pool, and Pest are separate services.
Which questions should I ask a matched tech?
- Which zones did you test, and what failed: head, valve, line, or controller?
- Is the dry shape consistent with coverage, or should a lawn professional look at insects or disease?
- What is excluded from the work (for example, new system design, permits, or major re-piping)?
- What is the written scope and timing, relative to any HOA deadline you shared?
Request a local irrigation tech when you have your notes and photos ready.

Questions from this guide
- Why is one zone dry after the system ran?
- Could be a head, a valve or a controller. The tech confirms.
- What should I send the tech after an HOA dry-zone notice?
- Photo, zone number if you have it, and the notice.
- Is this lawn care or irrigation?
- Irrigation. Mowing is a different match.
