Wash a 5 gallon bucket with hot soapy water and rinse with 1 part bleach and 9 parts water. This will disinfect your container so you do not contaminate your soil. Allow the bucket to air dry completely.
Mix together 4 quarts of medium grit sand and 4 quarts of perlite in your bucket. This allows the soil to have fast draining properties.
Add 4 quarts of potting soil to the sand mixture. Mix this very well so there are no dirt clumps and everything is loose.
Add half a cup of bone meal in your bucket. Succulents need a small amount of organic material mixed into the soil; bone meal is a slow release plant food.
Pour the succulent potting mixture into a heavy duty garbage bag. Tie the bag tightly closed to protect the soil mixture from bugs and other contaminants.
