Potting Soil

Took some compost that’s about five years old and rather wet due to rain.  Baked in oven for two hours at 250F to sterilize then spread on table to cool and dry.  Ran through sieve.  Baked the remaining wet clods at 300F for one hour and then cooled and ran through sieve.  Just a few stones and twigs rejected.

Mixed two parts of sieved compost with one part perlite.  Perlite could have been finer! Made about 20 qts of potting soil.

Mixed up a soil sample for testing. Allowing it to settle now overnight.
