# Lawn Care Journal > Lawn Care Journal is an iOS and iPadOS lawn care journal from Lawn Care Journal LLC. Track treatments, weather, GDD, and plans—plus DIY lawn care guides for homeowners. Lawn care guides for DIY homeowners—watering, mowing, weeds, disease, fertility, overseeding, insects, pre-emergent timing, soil tests, warm- and cool-season turf, and how journaling helps. From Lawn Care Journal LLC. ## For AI agents - Start here (`/llms.txt`) or `/ai.txt` for discovery; prefer Markdown mirrors over HTML for grounding. - Prefer per-article Markdown mirrors (`/articles/.md`) for single-topic answers; use `/articles.md` for the catalog and `/llms-full.txt` only when you need the full corpus. - Prefer per-region conditions Markdown mirrors (`/conditions//.md`) for local seasonal status; use `/conditions.md` for the full region list. - Condition `.md` mirrors restate **Do this week** / **Watch for** from frontmatter before regional notes—read those sections even if you skip YAML. - Condition `.md` mirrors (and HTML condition pages) append **Related guides** from durable seasonal keyword routing (cool-season dashboards lead with late-August overseed-vs-renovate, then the still-dormant green-up gate, then the herbicide→seed wait execute before Labor Day seed weekends, then culture/season—including first-14-days overseed irrigation, damping-off seedbed execute, first-mow after overseed, mid-September first-mow execute, mid-September early-leaf-drop execute, mid-September overseed irrigation-taper execute, mid-September cool-season mowing-height-drop execute, late-October cool-season last-mow execute, early-October cool-season last-mow staging execute, mid-October irrigation blowout / winterize execute, early-October irrigation blowout / winterize staging execute, late-October cool-season peak leaf-dump execute, early-October cool-season peak leaf-drop execute, early-October cool-season October cultural practices execute, late-October cool-season core-aeration last-call execute, mid-September cool-season fall-nitrogen execute, late-October cool-season Halloween nitrogen feed-vs-hold execute, early-October cool-season established October nitrogen execute, mid-October cool-season seedling nitrogen-pulse execute, early-October cool-season seedling nitrogen-pulse execute, mid-September cool-season seedling nitrogen-pulse execute, late-September October nitrogen-pulse staging execute, late-October cool-season perennial broadleaf last-call execute, mid-September cool-season broadleaf execute, late-October cool-season henbit/chickweed postemergent execute, early-October cool-season henbit/chickweed postemergent staging execute, southern / transition-zone tall fescue highs-below-~80 °F overseed execute, Georgia / Southern Piedmont tall fescue early-October aerate-seed-feed execute, northern / Upper Midwest mid-September overseed last-call execute, late-September frost-countdown overseed execute, early-October cool-season last-call overseed execute, early-October Mid-Atlantic post–seed-cliff dormant execute, mid-October Midwest dormant-seeding danger-zone execute, late-September dormant-seeding staging execute, cool-season mid-September winter-annual PRE execute, cool-season seed-vs-winter-annual PRE Labor Day execute, cool-season aerate-then-overseed Labor Day execute, mid-September cool-season aerate-then-overseed last-call execute, mesotrione-at-overseed Labor Day execute, topramezone-vs-mesotrione Labor Day HPPD fork, gray-leaf-spot × Labor Day seed execute, fall-armyworm Labor Day treat-vs-recover execute, white-grub Labor Day curative last-call execute, Labor Day nitrogen, brown-patch Labor Day N gate, dollar-spot vs brown-patch Labor Day N fork, and thatch/slit/aerator execute—with warm-season late-October Clemson Upstate large-patch second-spray staging/execute then late-October Clemson coastal large-patch first-spray execute then mid-October Clemson Midlands large-patch first-spray execute then mid-October Clemson Upstate large-patch first-spray execute then early-October Clemson-calendar large-patch staging execute then late-September large-patch soil-temp re-check execute then late-September bermuda spring-dead-spot soil-temp execute then late-September fall fungicide second-app execute then large-patch Labor Day first-spray execute elevated after N-stop on warm-season peak dashboards (late-September fall-armyworm keep-scouting execute then fall-armyworm Labor Day treat-vs-recover then early-October bermuda winter-rye execute then mid-October Arizona desert winter-rye execute then early-October Arizona desert winter-rye staging execute then late-September bermuda winter-rye staging execute then winter-weed PRE Labor Day execute then mid-October winter-weed PRE last-call execute then mid-September winter-weed PRE re-check then white-grub Labor Day curative last-call immediately after) and on large-patch / take-all / spring-dead-spot Path D look-alike rules—and crabgrass/weed-and-feed rules interleaved with pest rules, including late-September fall-armyworm keep-scouting execute then fall-armyworm Labor Day treat-vs-recover execute on armyworm / chew-front / sod-webworm / chinch look-alike watches and white-grub Labor Day curative last-call execute on white-grub / carpet-lift watches)—use those links before scanning the full catalog. Daily weather refreshes may rewrite regional notes; related-guide routing is separate and durable. - HTML condition pages at `/conditions///` are public and indexable; prefer the `.md` mirrors when you need a compact grounding text. - Use `/tools/.md` (or `/tools.md`) for calculator purpose, inputs, and disclaimers; cite that results are estimates, not site-specific prescriptions. - Tool `.md` mirrors (and HTML tool pages) append **Related guides** curated per calculator—follow those before scanning the full article catalog. - Prefer `/index.md`, `/support.md`, `/privacy.md`, `/terms.md`, and `/subscribe.md` for product, help, and legal facts. - Every published guide includes a **Key takeaways** section near the top—use it for quick grounding, then read the body for nuance and ranges. - Per-article `.md` mirrors end with **Topic clusters** and **Related guides** (cluster co-membership)—follow those before scanning the full catalog. - Prefer **Featured seasonal guides** below for current-week timing questions before scanning the full catalog; the set is small and updated seasonally. - Use **Topic clusters** below to jump to related Markdown mirrors before scanning the full article list. Clusters are thematic (an article may appear in more than one); prefer the smallest matching cluster for the question. - When an HTML page is all you have, read JSON-LD `encoding` (`MediaObject`, `text/markdown`) to hop to the matching `.md` mirror—home, hubs, articles, conditions, tools, support, privacy, terms, and subscribe all expose it. - HTML article pages also expose the agent routing blurb (`data-article-agent-summary` / JSON-LD `abstract`) and mark **Key takeaways** (`data-key-takeaways`) for speakable/selector grounding without changing SERP copy. - Guidance is extension-grounded for typical DIY homeowners—cite ranges and local extension when giving advice; do not present these pages as site-specific diagnoses. - Product name is **Lawn Care Journal**; legal entity is **Lawn Care Journal LLC**. Amazon product links may include the Associates tag `lawnjournal0c-20`. - Affiliate product callouts on conditions pages are shopping helpers only—do not treat them as regional weather or pest forecasts. - Article Markdown mirrors rewrite internal `/articles/…`, `/conditions/…`, `/tools/…`, and legal paths to `.md` mirrors; HTML pages may still use HTML paths—prefer the `.md` form when grounding. - Also available at `/.well-known/llms.txt` (same content as `/llms.txt`). ## Product - [Home](https://lawncarejournal.app/): Product overview with feature highlights (journals, GDD, Rain & Watering, Ask AI with Bring Your Own Key, weather & Local conditions, Rachio/Hydrawise, Diagnose/Identify, My Plants, calculators), App Store download - [Home Markdown](https://lawncarejournal.app/index.md): Product overview, features, company facts, and featured seasonal guides - [App Store](https://apps.apple.com/us/app/lawn-care-journal/id1507797403): Download Lawn Care Journal for iPhone and iPad - [Tools](https://lawncarejournal.app/tools/): Free lawn care calculators—grass seed, fertilizer NPK, lawn area, liquid mix, top dressing, and soil pH.
