Light: Prefers medium to bright indirect light—keep out of direct afternoon sunlight. The more sunlight your plant receives the more likely it produce lovely white flowers. When placed in low light your plant will look more like a traditional foliage plant - less likely to produce flowers. 

Temp: Does well at room temperature between 60°F - 77°F. Cold drafts should be avoided.

Water: Water when the top 50% of soil is dry. It is more tolerant of underwatering than overwatering. The Peace Lily will start to droop when it’s ready for a watering. Clean the leaves of your Peace Lily by wiping them down with a damp cloth.

Humidity: Benefits from extra humidity. 

Toxicity: Toxic to pets

 

Trouble shooting

Wilting plant or curling leaves, dry potting mix: suggests underwatering.

Yellowing leaves, mushy black stems: indicates overwatering. 

Browning leaf tips: indicates lack of water, dry air,  or too much sunlight.
