My bi-color calla lily plant is potted. Its leaves are turning yellow. What does this mean? I live in a climate where in the summer the temperature can rise over 100 degrees Farenheit. I need tips for long life care. If I can make a homemade mix of nutrients, is it cost effective since it is potted?

I'd stick with a commercial fertilizer, either chemical or organic. It's cheaper in the long run.
