What is the ideal pH range for most nursery plants?

The ideal pH range for most nursery plants is slightly acidic to neutral, around 6.0 to 7.0. This range is optimal because it allows for the maximum availability of essential nutrients in the soil, which can be absorbed by plant roots effectively.

In this pH range, nutrients like nitrogen, phosphorus, potassium, and many micronutrients remain soluble and are readily accessible to most plants. A pH of 6.0 to 7.0 supports healthy microbial activity in the soil as well, which is crucial for nutrient cycling and overall soil health.

Having a pH that is too low (acidic) can lead to nutrient deficiencies and potential toxicity from elements like aluminum, while a pH that is too high (alkaline) may cause micronutrient deficiencies. Therefore, maintaining a slightly acidic to neutral pH is essential for promoting robust plant growth and vigor in nursery settings.
