🌾 Soil note
Most US clay/loam soils run slightly alkaline (pH 6.5-7.5). Most vegetables grow fine without amendment. Blueberries are the exception — they NEED pH 4.5-5.5 and require sulfur + peat + ammonium sulfate amendments. Test soil before amending. Apply lime in fall for spring planting; sulfur takes 3-6 months to fully react.

📖 Gardening Glossary
Plain-English explanations of the terms you'll see throughout LOAM. Search for a term or scroll the list.
📍 Detect zone from ZIP
Enter a US ZIP code and Loam will estimate your USDA hardiness zone.
You can always pick a different zone manually from the dropdown.
Note: Auto-detect uses latitude as a proxy for zone — accuracy is ±1 sub-zone for most of the country.
Mountain, coastal, and microclimate areas may differ. If you know your zone, manual selection is more reliable.
