What is the best thing to feed them? I used bone meal in the soil when they were planted. They haven't bloomed yet, just the long green stalks now. I am in Mesa Arizona. Thanks!
I would suggest an evenly balanced time-release, granular or water-soluble fertilizer, used in accordance to package directions.
