Site Considerations

Figure 1. Climatic Zone Map for Alabama and Georgia Species selection, establishment methods, and maintenance procedures should all be based on site characteristics including climate, soils, slope, aspect, and land user objectives.


This publication recognizes three climatic zones (see Figure 1). The map provides a convenient means of determining where particular plant species can be successfully grown. Following the correct planting dates in each climatic zone will greatly increase success. No planting date is given if a species is not adapted.


The major soil types are sandy, loamy, or clayey. Soils are diverse throughout the region and often within a site to be planted. Deep sandy soils should be considered droughty because they do not hold much moisture. Clayey soils on steep slopes may be droughty also, because rainfall runoff is higher than on other soils. Loamy soils are generally best suited for wildlife plantings since these soil types have good water holding capacity, are more fertile, and are easier to prepare for planting. Poorly drained soils are not suited for a wide array of plant species and should be planted to adapted erosion control varieties.


The slope of the area to be planted is an important consideration related to soil erosion. Steep slopes usually limit planting annual varieties because of the erosion hazard and droughtiness. The steeper the slope the more essential it is to establish an aggressive perennial cover. Steep slopes limit the use of equipment for seedbed preparation, planting, and maintenance and require mulching.


Aspect affects soil temperature and moisture availability. Slopes facing the south and west tend to be warmer and drier than north and east facing slopes. On south and west slopes, mulch should be used to retain soil moisture. Warm-season perennial species tend to do better on slopes facing the south and west because they are usually more drought tolerant than cool-season species.

Cool-season perennial species are more successful on slopes facing north and east. On shaded sites, fall plantings do best on south and west aspects because of more sunlight and warmer soil temperatures.
