The last few years have bought a bag or two of potting soil for my spring planting though each year I am disappointed when I open the bag containing a bunch of bark , twigs, gravel, and even several pretty large rocks.
This year I have decided to make my own potting soil with very little effort and much less cost. Given I just recently harvested my compost bin and got about 15 gallons of screened compost as my starting point to make my own mix.
CVG Potting Soil Recipe
- 15 gallons of screened compost
- 1 brick coconut coir (hydrated)
- 4 cups of vermiculite or perlite
- 1 cup organic fertilizer
Add all ingredients to 20 gallon trash container. Mix thoroughly with large shovel until everything is well incorporated. Cover with lid with several holes drilled in the top (otherwise moisture+no light = mold growth)
You can use a smaller container than 20 gallons but would not recommend one smaller or it can be a decent reach to get the last of the soil out of the bottom…
