Soil pH: Affecting Pigment Expression
Soil pH can also influence the color of irises. Different iris varieties may have different pH preferences, and the acidity or alkalinity of the soil can affect the expression of pigments within the petals. For optimal color development, it is essential to ensure that the soil pH is appropriate for the specific iris variety being grown.
Nutrient Availability: Supporting Pigment Production
Adequate nutrient availability is essential for healthy iris growth and vibrant color expression. Irises require a balanced supply of nutrients, including nitrogen, phosphorus, and potassium, to produce the pigments that give them their characteristic hues. Insufficient nutrient levels can result in paler or less intense colors.
