Hi Kyle

Peace Lilies (Spathiphyllum) are susceptible to a few insects such as aphids, spider mites, and mealy bugs. However, insect problems are very minimal with peace lilies. Insect problems can be taken care of with insecticides, insecticidal soap or by washing the plant. Root rot, leaf spot and bacterial soft rot do occur in peace lilies, but are usually the result of improper care. Diseases can be taken care with fungicides or proper care methods including good drainage and re-potting.
Peace Lilies (Spathiphyllum) prefers an evenly moist environment. For plants grown in soil, drainage is important; your peace lily pot should have drain holes. Watering your peace lily once a week is usually sufficient. However, when the plant is grown in low light levels or cooler temperatures water requirements may be less. Water requirements may increase with brighter light levels or warmer temperatures and during periods of rapid growth; use tepid water when watering or misting.

Testing the soil before watering by sticking finger in soil up to first knuckle can help you determine the need for water - if soil is moist don't water. Placing the peace lily in high humidity or creating a humid environment is beneficial to the plant. Peace Lilies are good candidates for hydroponics. Peace lilies are susceptible to chlorine damage; let chlorine evaporate from tap water before using or use distilled water. Over-watering may cause leaves to turn yellow and under-watering may cause plants to wilt and the leaf edges to turn yellow or brown.  Hope this helps, kathy
