Question: are calla lilies acid loving plants?
Answer: They like a very acidic soil. ... Essential nutrients are most available to lily (lilium) plants at 6.0 to 6.5 soil pH, and Calla lily plants at 5.5 to 6.0. Similarly, most horticultural plants grow best in soils with a pH between 6 (slightly acid) and 7.5 (slightly alkaline).
