Garden Guides How Does Sand Clay or Potting Soil Affect

Sep 21, 2017 Clay Soil. Clay soils are more dense than sandy soils and hold water very well. Water drains slowly in clay soils, causing puddles. Plants sitting in puddles for too long can cause mold, rot and other diseases. If the roots become waterlogged and rot, the plant will eventually die if it is not allowed to dry out between watering.
