The longer the oak leaves remain in the soil, the more alkaline they become. Because the acidity of freshly fallen oak leaves is short lived, they are ineffective as pH modifiers. For instance, soil that has a pH of 7.0 or above is not adequate for plants that require an acid soil.he Scarlet Oak leaf is the most acidic and the Chestnut Oak leaf, the least. Oak leaves added to the soil in their freshly fallen state lower the pH of the soil -- somewhat.
