Garden Topic Guides
Each guide explains the "what and why" and includes a free, interactive tool you can use with your own numbers and print.
Planting Calendar by Hardiness Zone
Build a month-by-month planting calendar from your USDA zone and local freeze dates — what to start indoors, sow, transplant, and harvest.
Lawn Care Month by Month
A season-by-season lawn care schedule: mowing height, fertilizing windows, watering, aeration, and overseeding for cool- and warm-season grasses.
Organic-First Pest Control (IPM)
Identify common garden pests and get organic-first, then chemical, treatments — with prevention that actually works.
Weed Control That Actually Works
Identify crabgrass, dandelion, clover, nutsedge, and bindweed, and control them with cultural, organic, and chemical methods.
How Much to Water Your Garden
Estimate weekly watering needs in inches and gallons for beds and lawns by climate, sun, and plant type.
Fertilizing Vegetables & Lawn
Convert your garden area and a fertilizer's N% into exactly how many pounds to apply — and when.
Raised Bed Gardening
Plan, build, fill, and cost a raised garden bed — sizes, materials, soil mix, and a printable budget.
Companion Planting
Pair plants that help each other — pest repulsion, pollination, and efficient space — and plan the timing with a calendar.
Starting Seeds Indoors
Start warm-season seeds indoors on a schedule tied to your last frost date, then harden off and transplant.
Composting at Home
Build a compost system for free soil amendment: bins, greens vs browns, and a budget for setup.
What makes these guides different
There are 10 guides here, and every one of them ends in a working tool rather than a summary. That structure is deliberate. A general explanation of when to water, how to read a fertilizer bag, or what a hardiness zone means is the kind of thing an answer engine can satisfy in a paragraph — and once a reader has that paragraph they have no reason to visit a site. A calculator that takes your own area, crop, state, and soil and returns a printable sheet to take outside is a different kind of object: the answer depends on inputs only you can supply, so the guide and the tool have to be used together.
In practice that means each guide is written to explain the reasoning behind the tool’s output, not to replace it. The planting calendar guide explains why frost dates set every downstream decision and why cool- and warm-season crops run on different rules; the tool then turns your state and crop into actual dates. The fertilizing guide explains what N-P-K does and does not tell you and why a soil test is the real starting point; the calculator converts your area and a bag’s concentration into pounds. Read the guide for the reasoning, run the tool for the number.
Where to start, by problem
If you are planning a season before anything is in the ground, start with the planting calendar, then starting seeds indoors, then raised beds if you are building, and companion planting if you are laying out a bed. If something is already going wrong, go to organic-first pest control, weed control, the plant problem pages, or the symptom diagnoser. If the problem is soil or water, the watering, fertilizing, and composting guides cover the three inputs that most often explain a disappointing bed.
How to read the guidance
Everything here is framed around climate data rather than fixed dates, because a single planting date is wrong somewhere in almost every state. Hardiness zones follow the 2023 USDA Plant Hardiness Zone Map, and freeze dates are typical 30-year normals from state cooperative extension services — typical values for planning, not forecasts. Where a state or a metro spans several zones, the pages give the bracket and say so, and the ZIP lookup exists to resolve the ambiguity for your own address rather than leaving you to guess which end of a range applies to you.
The final step belongs to your county extension office, your soil test, and the label on anything you apply. Those three things are local and current; a website is neither. Where a figure could not be verified, the page says so rather than substituting an estimate, and where guidance depends on a product or a jurisdiction we point at the authority instead of paraphrasing it. That is a deliberate editorial position: for advice someone will act on outdoors, a named gap is more useful than a confident guess.
