What This Means for Your Garden
We don't have a soil survey record for GRATON, CA (95444) in our dataset yet, so this page doesn't list a soil type, pH or drainage class rather than guess at them.
To see the soils actually mapped under your property, open the free USDA Web Soil Survey, draw an area of interest around your lot and read the map units it returns. Soil can also change from one end of a yard to the other, so for pH and nutrients the reliable answer is a test: the Cooperative Extension service in your state runs lab soil tests, and a home kit gives you a quick pH reading.
Your USDA hardiness zone is 9a, meaning winter lows can reach around 20 degrees Fahrenheit. This determines which perennials, trees, and shrubs will survive winter in your area. The zone 9a planting guide lists what grows well at that winter low.
How to Improve Your Soil
