Soils and Topography Topography refers to the slope and contour of the land. Topography will influence drainage of water and the sun exposure of your landscape. For example, South facing slopes are warmer and drier than North facing slopes. The types of plants and animals living on a South facing slope will differ from that of a North slope. Different kinds of plants also require different types of soils.
Soils vary with regards to pH, texture, and nutrients.
A good knowledge of your soils is the foundation for your decision as to where and what type of plants you will plant. Soil surveys are available from your County Extension Office.
