my plant is endless. It is so big its like a huge monster in the corner. It likes plenty of water otherwise the long stalks go limp. I get flowers very often.

My Peace Lily plants flower frequently but the flowers stay a pale green and do not turn white. I asked at a plant store and was told they need lots of direct sunlight. I know that is not correct as direct sun burns the leaves. I have fertilized with miracle grow according to directions. Any suggestions?

Been growing 3 of them for years, colder weather brings them into bloom, when the leaves droop water them, I cut of leaves that look bad which make it grow stronger and cut of tips that are brown, they are in door most of the time. In summer I take out side and leave out all night never leave in bright sun light. They love rain water. I even clean leave with water and rag which they like a lot, leaves get bright and shiny. Alway use light warm water. they can grow big. Just replant to a bigger pot and so on and so on as they get big.

I revived a Spathiphyllum that my daughter took out in cold weather. The leaves turned dark and went limp. I cut the plant down to one inch above the dirt, watered well and set it in a east window. Within days in started to shoot new growth and is now 6 months later, it is a lush green plant again. I have found that they are hard to kill if you water regularly.

This plant loves water and is the indicator for all of my plants. When it is thirsty, all of the stems droop. One good watering and the next day, it is as good as new. I love this plant.
