“What is the average pH range of your various gardening soils? I bought 2 varieties – the Waterhold, and the Natural & Organic Potting Mix + fertilizer.” Question from Michael of Scottsdale, Arizona.
Answer: Great question Michael! The right pH is essential for growing good potted crops and container specimens. That’s why Black Gold mixes are fortified with alkaline Dolomite Lime to naturally increase their pH to a target of 6.5–a close-to-neutral pH ideal for many garden plants. We then test our mixes to make sure their pH is within the correct range.
