Rapid drainage and hydrology
While specific drainage classes are not listed, the high sand content implies a very well-drained landscape. This makes the soil excellent for building foundations but may require more frequent irrigation for thirsty crops.
Zone 7b gardening success
The warm 7b climate allows for a variety of perennial herbs and long-season fruits. Take advantage of the sandy texture by planting root vegetables like carrots and parsnips that can expand easily in loose soil.
