Ideal pH Levels for Fruit Trees

When a plant is in soil that is not optimized for its growth needs, essential minerals and nutrients become locked up in the soil, unavailable to the plant. If your fruit tree is not as healthy as it should be or if it doesn’t provide ample amounts of fruit, you should conduct a soil test to see if the soil pH level needs adjusting.

For most plants, the optimum pH range is from 5.5 to 7.0. But some plants will grow in more acidic soil or may require a more alkaline level. The pH is not an indication of fertility, but it does affect the availability of fertilizer nutrients.
