Growing peonies can be a bit tricky, especially when it comes to their soil preferences. Peonies thrive in slightly acidic to neutral soil pH, typically between 6.0 and 7.0.

This pH range allows peonies to absorb essential nutrients from the soil. Soil pH outside of this range can lead to nutrient deficiencies, stunted growth, and poor blooming.

A soil pH that's too low (acidic) can cause iron and manganese deficiencies, while a pH that's too high (alkaline) can lead to boron toxicity.
