Apples prefer a slightly acidic to neutral soil (pH between 5.8 and 7.0). Extreme soil pH values result in nutrient tie-up or toxicity and poor tree and fruit development. It is important to amend the pH in acidic soils by incorporating lime before planting.

What soil pH do apple trees need?

Soil pH in the 6.0 – 7.0 range is ideal for growing fruit trees. Fruit trees can tolerate a wide range of soil acidity however they prefer a pH of 6.0- 7.0. When soil pH is outside this optimal range lime or elemental sulfur can be used to adjust the soil pH. Use ground limestone to raise the soil pH.

How do you acidify soil for fruit trees?

To raise the pH of acidic soils, add crushed limestone. To lower it, apply nitrogen or elemental sulphur. For so-called acid-loving plants such as azaleas, tomatoes and blueberries, I always use some form of pine mulch, usually pine straw.
