Calla Lilies Reverting to Pink: Nutrient or pH Effect?

Multi-Color Callas Turning Uniform Pink Year 2

Unusual color shift suggests nutrient influence. Try bone meal/bulb food (high P/K). Some flowers change color with soil pH (hydrangeas: pink=alkaline, blue=acid). Contact grower if feeding doesn't restore mix.

Investigation Steps

• Apply bloom fertilizer (low N, high P/K)
• Test soil pH
• Document color changes
• Contact supplier for variety info

Color reversion in callas is rare but nutrient-linked.
