Question
Hey Darlene,
Thanks for your time :). I've read numerous posts about Spathiphyllum and many relate to my case, but some cease to go into appropriate detail. When we moved into our new house, there was a Peace Lilly in the bathroom, out of sufficient light and looked almost dead. Since then, I have managed to get the leaves green-ish again and it has sufficient foliage ?in fact it is rather monstrous. However, I re-potted it from its former pot because it had no drainage. Since then, it has never flowered. I water it when the soil begins to get bone dry (maybe once every three or four weeks). May it not be flowering because it is not root bound?- it has been in its new pot for approximately a year. I also have another Spathiphyllum (.. sorry this is dragging on a bit) which was new in a small - very small - pot. It was flowering nicely but looked tiny compared to it's sister on the other side of my table. I re-potted it into a new pot and now, no new flowers are forming and one that was forming has turned yellow and looked like it had a magnesium deficiency (which it doesn't), so I cut it off. May this again be because it is not root bound? The Lillies are both in my room quite far away from a south facing window, but they get good light.

Thanks again,
Adam


Answer
Adam,

Yes, peace lillies prefer to be root bound and produce more blooms when they are.  How do you know you do not have magnesium deficiency?  I would suggest that you do 2 things. First apply a half cup of epsom salts (magnesium sulfate) to the larger one and a quarter cup to the smaller one. Then start fertilizing it onc a month with a water soluable fertilizer like Miracle Grow that is labeled Bloom building for flowering plants.  Those 2 things along with becoming rootbound should cause both plants to start producing flowers. Good luck.
