Why Acid-Loving Crops Thrive at pH 5.5 in Hydroponics
Update: 2025-11-18
Description
In this short episode Dr. Russell Sharp explores which crops naturally prefer acidic conditions and explains why, when grown hydroponically, they are typically kept around pH 5.0–5.5 rather than the much lower soil pH they prefer. He covers examples like blueberries, cranberries, pineapple, tea and potatoes, and explains the roles of nutrient availability, soil biology and fertilizer practicality.
Dr. Sharp also teases the next episode contrasting acid-loving (ericaceous) plants with alkaline-loving (calcicole) species.
