Food-Gardening Lessons From A Wartime Victory Garden

What is the pH of Black Gold Potting Mix?

“What is the soil pH of Black Gold Natural and Organic Potting Soil?” Question from Michael of Pueblo, Colorado.

Answer: At production, the peat moss in our mixes has a pH range of 3.5-5.0, but we add liming agents to bring all of our potting mixes up to a more neutral pH range of 5.5-6.5.  Keep in mind, mix pH will change depending on your growing environment, irrigation water, the fertilizer you use, and the plant species you grow. For a highly detailed article on managing mix pH, read the Sun Gro article titled Managing Low pH in Growing Media for Reliable Crop Performance.

Happy gardening!
