Help for Peace Lilies


The peace lily is more closely related to anthuriums than it is to actual lilies. Included in the Spathiphyllum genus, this flowering tropical plant is well suited to living indoors in all climate zones. Its leaves are long and narrow and its flowers look a lot like the well-known red anthurium, but they are white. Your peace lily should bloom prolifically with little care, but things can go wrong if it doesn't receive the correct amounts of water and light.

Step 1

Move your peace lily into an area that does not receive direct sunlight if its leaves turn yellow. If you have a window that gets full sun for most of the day, move your peace lily at least 5 feet from the window.

Step 2

Water your peace lily well when you do water it, but be sure to allow its soil to dry out between waterings. You can even wait for its leaves to droop a bit before you give it a good soaking, according to the Clemson University Cooperative Extension Service. Don't wait too long though or the edges of the leaves may begin to yellow.

Step 3

Pinch off yellow leaves. Too much direct sunlight can cause this condition, as well as becoming too dry.

Step 4

Spray your peace lily with a fine mist of water twice a week to help the humidity level in your home more closely resemble that of its native tropical environment.

Step 5

Fertilize your peace lily every month or two with a plant food containing an N-P-K (nitrogen-phosphorus-potassium) ratio of 20-20-20, diluted to a quarter the strength stated on the label.

Step 6

Repot your peace lily every year or two years using a mixture of peat moss, sand and loam.

Step 7

Treat mealy bugs and other insect pests with a spray of insecticidal soap. Remove dust and other dirt from its leaves by gently wiping them with a moist sponge---this treatment can also help to remove any insects.
