Make Your Own Potting Soil
4 parts peat moss
2 parts compost
2 parts perlite or vermiculite or 1 part of each (the vermiculite was pretty expensive so I used the 2 parts perlite)
We used a wheelbarrow to measure our parts and an empty sandbox for mixing and storing. The children had a lot of fun mixing it up and Big Woman even had to get in with her bare feet and pretend she was Lucy in Italy smashing grapes in the wine vat. (Yes, we are I Love Lucy fans around here)
