How to pick the right tool
With 11 gardening tools plus the yard-rules family, the fastest way in is to start from the decision you are trying to make rather than the tool name. Timing decisions — when to start seed, sow, transplant, or expect a harvest — belong to the planting calendar and What to Plant This Week. Quantity decisions — how much water, how much fertilizer, how many plants fit, or what will it cost — belong to the watering, fertilizer, bed planner, and cost tools. Diagnosis decisions — what is wrong with this plant — belong to the pest finder, the symptom diagnoser, and the plant problem pages. And choice decisions — which variety, which grass — belong to variety compare and the grass guide.
Most tools ask for a state or ZIP because the underlying data is location-dependent. The frost dates, zones, grass types, and regional pest lists all vary by where you are, which is the reason a single national answer to any of these questions is not useful. If you have not looked your location up yet, start with the ZIP zone lookup and keep the zone and frost dates to hand — you will be entering them repeatedly.
What the tools do and do not know
These are calculators, not measurements. They reason from published data — USDA hardiness zones, extension freeze-date normals, spacing and days-to-harvest figures, published nutrient concentrations, retail cost ranges — and apply it to the numbers you enter. What they cannot see is your soil, your shade, your irrigation, your microclimate, or your local restrictions. That is why each tool page states plainly what it cannot know, and why the answers are framed as a starting point to adjust rather than a prescription. Where a figure is unknown, the tools show “verify locally” instead of estimating.
Every calculation runs in your browser. There is no account and no server-side processing, so the numbers you type are never uploaded or stored — and a printed sheet or a screenshot is the only copy that will survive closing the tab, which is why each tool offers a print output. If you would rather work on paper, the printable worksheets give you blank seed-starting, pest-scouting, and soil-amendment templates to fill in by hand. The topic guides explain the reasoning behind each tool, which is usually worth reading once before relying on the numbers.
