Answer: Lack of nutrients can keep your peace lilies from blooming. Other requirements are bright to medium light, moderately moist soil, moderate to average humidity, and normal room temps. Use a fertilizer higher in phosphorous (the middle number) to promote bloom. The numbers on a fertilizer bag refer to the percentage of N (nitrogen), P (phosphorous), and K (potassium) in the bag. There are different formulations for different purposes. In general terms, nitrogen produces lush green growth, phosphorous helps strengthen stems and produce flowers, and potassium keeps the root system healthy. Too much nitrogen can result in lots of lush, green foliage, but at the expense of flowers so use a fertilizer with a higher middle number such as a 10-15-10. Good luck with your plants!
