Everything on Garden Bed Math is a planning guide or a record-keeping aid, not a guarantee.
- Zone and frost data are averages over many years. Any one winter can be colder, and any one spring can have a later frost.
- Our zone finder is not the official USDA Plant Hardiness Zone Map. It repeats the published 2023 zip-code listing without changes.
- Quantities come from formulas and published bag sizes that may not match the product you buy. Check the label and measure your beds.
- We don't recommend pesticides, herbicides or fertilizer products, diagnose pests or diseases, or say whether a plant is safe to eat. Ask your local extension office about those.
- Published figures change. Each page shows the date we last checked its sources.
