Peace lily is a popular indoor plant, valued for its easy-going nature, its ability to grow in low light environments, and last but certainly not least, the beautiful white flowers, which bloom nearly nonstop. Although this plant isn’t fussy, it’s important to understand how to water a peace lily. Read on for the details of peace lily watering requirements.

When to Water Peace Lily

Poke your finger into the potting soil to determine if it’s time to water your peace lily. If the soil feels moist to the first knuckle, it’s too soon for watering peace lilies. If the soil feels dry, it’s time to give your peace lily a drink of water.

If you like high-tech gadgets, you can use a water meter. However, the knuckle test is just as reliable and considerably cheaper.

The best way to water a peace lily is to set the plant in the sink. Pour water slowly onto the soil until liquid drips through the bottom of the pot. Let the plant drain thoroughly, then return it to its drainage saucer.

Never let the plant sit in water, as disease caused by excess water is the number one reason for houseplant death. Too little water is always preferable to too much water.

Peace lilies can stand a fair amount of neglect, but allowing the soil to become bone dry may result in a sad, droopy plant. However, peace lily will nearly always bounce back with a good watering.

Peace Lily Watering Tips

Tap water is fine for watering peace lilies, but letting the water sit out for a day or two allows fluoride and other harmful chemicals to dissipate.

If water runs straight through the pot, it may mean the plant is badly root bound. If this is the case, repot your peace lily as soon as possible.

If you forget to water your peace lily for an extended time, the edges of the leaves may turn yellow. If this happens, water the plant well, then clip off the yellowing foliage. Your plant should soon be good as new.
