TheGardenLady received a question from Billie on her post  “Caring for Sick Peace Lilies”.

I have a peace lily that has sympathetic value.  And it looks awful. I have not moved it. It has been in same spot since april. The leaves are wilting and just hanging over the edge of pot and the leaves are starting to turn brown. It has been like this a couple months. I tried watering it, putting it outside under ashade tree and fertilized it. I recently re-potted it. But thats not helping. I dont know what to do. Please help

Peace Lilies, Spathiphyllum, like well-drained soils that are relatively acidic and like warm temperatures.  (see here) You should be fertilizing the Peace Lily plant regularly during the growing season to maintain a dark green foliage color.Usually the Peace Lily is a plant that is resistant to most problems. However, occasionally mites, scales, and/or mealy bugs may be a problem. So check your plant leaves. If you have properly cared for your Peace Lily and have ruled out any insect problems, a last try is to repot the plant in new soil. Try one of those brands of potting soils that have slow release fertilizer. (see here)

One problem for plants kept in pots is that there is so little soil in the pots that the soil might not be able to do its job after a while. For example salts can build up in the soil from the fertilizers that were used over the years. (see here)  Fertilizers are salts and if you do not water thoroughly, salts can become concentrated in the soil in pots. High soil-salt concentrations are toxic to roots and can kill a plant. Peace Lilies are one plant that cannot tolerate any salt build up.
