Often asked: What Happens When An Oak Tree Gets Too Alkaline Of Soil?

Soils with a pH of 7.0 are said to be neutral, while anything lower is acidic and anything higher is alkaline. Most plants, including oak trees, prefer a pH that is neutral to acidic and higher pH can make soil nutrients unavailable to the tree, effectively causing malnutrition.

How does an oak tree affect the pH of the soil?

  • Before you can understand how the leaves of an oak tree affect the pH of your soil, it’s important to understand what the pH scale is. It determines the acid and alkaline levels in soil, and ranges from 0.0 to 14.0. Neutral soil measure 7.0 on the pH scale.

What happens if soil is too alkaline?

For many plants, soil that is high in alkalinity makes it harder for plants to drink in nutrients from the soil, which can limit their optimal growth.

What pH soil do oak trees like?
