At what pH range do acid-loving plants grow best?

Acid-loving plants thrive in a pH range of 4.5 to 5.8, which is considered slightly acidic soil. This specific pH range facilitates optimal nutrient availability for these plants, allowing them to absorb essential micronutrients such as iron, manganese, and zinc, which can become less available in higher pH levels.

In soil with a higher pH, such as 6.0-7.5 or above, the availability of these vital nutrients can be reduced, leading to nutrient deficiencies that can adversely affect the health and growth of acid-loving plants. Similarly, a pH lower than 4.5, while acidic, can lead to toxic levels of certain minerals and poor overall plant health. Therefore, the 4.5 to 5.8 range is ideal for supporting the unique needs of these types of plants.
