Yard & Outdoor Basics: Start Here

This hub is the outside of the house: lawn problems, fall and winter yard work, gutters, decks, drainage, and pests. The guides aim for the minimum that keeps the yard healthy, with timing drawn from university extension services for your region rather than a single national calendar.

How to use this section

• The lawn looks wrong: start with the symptom guides: brown patches while watering, mushrooms after rain, grass dying along the sidewalk every winter, water pooling in one spot.
• Seasonal work: the fall cleanup checklist, raking versus mulching leaves, how late you can seed, and the winter prep that protects faucets and gutters.
• Structures and drainage: gutter guards, a deck that feels spongy, grading, and mosquito control that actually works.

What you can expect from these guides

Timing, seed rates, and plant-care rules come from land-grant university extension pages and are cited in each article. Guides are reviewed by peter.bae, and each one lists its sources at the end.

All 12 guides in this topic

• Should You Rake Leaves or Leave Them on the Lawn Over Winter? — Leave light leaf cover, mow a moderate layer into the grass, and remove whole leaves that hide it. University trial numbers, snow mold, and where leaves go instead.
• Why Does My Hydrangea Bloom Great One Year and Barely Flower the Next? — Bigleaf hydrangea buds form in late summer, so an August pruning, a fall freeze, or a spring frost after early leaf-out can erase a year of flowers.
• Why Does Grass Along the Sidewalk Die Every Winter (But Not Elsewhere)? — The dead strip is de-icing salt. Rock salt quits at 15°F, so cold-day salting lands in the grass. Doses, de-icer temperatures, and a repair schedule.
• Why Does My Deck Feel Spongy in Some Spots But Not Others? — A spongy deck spot is rot where water sits and can’t dry. Where it is tells you if it’s one board or the frame, and soft wood has already lost much of its strength.
• Why Does Water Pool in One Spot in My Yard Every Time It Rains? — A spot that puddles every rain is low, compacted, or fed by runoff. Use the 6-hour hole test, a pen test, and thin topdressing to find and fix which it is.
• Why Are Mushrooms Suddenly Growing All Over My Lawn After Rain? — Rain makes soil fungi feeding on buried wood or roots fruit. They rarely hurt grass, but one common lawn species is North America’s top poisoning mushroom.
• Do You Still Need to Clean Gutters If You Have Gutter Guards? — Yes: guards cut debris but don’t end upkeep. What to check, why wildfire areas need metal guards and clear gutters, and the ladder math to do it safely.
• Why Does Part of My Lawn Stay Brown Even Though I Water It? — A brown spot that watering won’t fix is usually a coverage gap, grubs, dog urine, or brown patch fungus. The tests and thresholds that tell which one.
• How Late Can You Seed Grass in Fall and Still Have It Grow? — Tall fescue and bluegrass stop establishing once soil falls to 50°F. Regional cutoffs, what each week of delay costs, and when to switch to dormant seeding.
• Mosquito Control That Actually Works (and the Gimmicks That Don’t) — Empty and scrub containers weekly, dose Bti by surface area, and skip zappers and ultrasonic plug-ins. The evidence behind each, plus a gadget scorecard.
• Fall Yard Cleanup Checklist: What Actually Matters Before Winter — The fall yard jobs that prevent damage (gutters, outdoor faucets, risky branches) versus the ones you can skip or mow over, with the research behind each.
• Low-Maintenance Lawn Care: The Bare-Minimum Yearly Schedule — Mow at the right height for your grass, leave the clippings, and fertilize once at the right time. Extension heights, dates, and bag math inside.
