Frost dates, planting zones, soil types, and what actually thrives in Kansas — from mountains to coast.
Frost dates & zones
Kansas spans USDA zones 5b (northwest KS / Colby area) to 6b (southeast KS / Pittsburg area). Verify your exact zone and frost dates with your county Extension office — elevation and microclimates create real variation.

Western KS soils are naturally productive but alkaline — do NOT add lime. Eastern KS clay needs compost and organic matter. K-State Extension county offices provide soil testing at low cost.
Know your soil
Western Kansas has deep, productive silt loam — the breadbasket soils that grow winter wheat. Eastern Kansas has heavier clay loam that needs organic matter. The Flint Hills have thin, rocky soils over chert-laden limestone. All Kansas soils tend toward alkalinity — test before adding lime.
