High desert gardening High desert gardening Grasslands on the high plains will actually keep the soil stable. If you live in these areas between approximately 4,000 to 7000 feet you will need scrubs planted to prevent erosion and also grasslands. In some areas there will be no shade and lots of wind.
Evaporation occurs quickly when any moisture is in the soil with the heat of each day.
The soil will vary depending on the area of the Southwest that you live, from clay soils to sandy loam. When you have a lot of grass density all the grass and shrubs will be competing for any moisture they can obtain. Sometimes a wide area will not have growth and other times there will be heavy grass. The growth will depend on the type of soil, the moisture that the soil obtains and also the type of grass planted especially on slopes. In some areas blue grama will thrive especially on the shortgrass prairie while in the drier areas black grama will thrive.
