The Ideal Soil pH for Celandine

Celandine: Optimal pH Range and Its Importance

Celandine (Chelidonium majus) thrives in a soil pH range of 6.5 to 7.5, preferring neutral to slightly alkaline conditions. This pH range is optimal for Celandine’s growth, flower production, and the synthesis of its characteristic yellow sap. Within this range, Celandine can effectively absorb essential nutrients, particularly nitrogen and potassium, which are crucial for its rapid growth and medicinal properties. The plant’s adaptability to various soil conditions contributes to its widespread occurrence in both wild and cultivated settings. While Celandine can tolerate a slightly wider pH range (6.0 to 8.0), maintaining the ideal range ensures the best performance and potency of its compounds. In acidic soils (below 6.0), Celandine may experience reduced nutrient availability, especially calcium. In strongly alkaline soils (above 8.0), the plant might suffer from iron deficiency. Proper pH management is essential for encouraging vigorous growth, abundant flowering, and maintaining the plant’s traditional medicinal uses.
