Making your own potting soil

10.9 years ago cheap, compost, fertilizer, soil sifter

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

Ingredients:

• 15 gallons of screened compost
• 1 brick coconut coir (hydrated)
• 4 cups of vermiculite or perlite
• 1 cup organic fertilizer

Directions:

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…
