Peace Lilies do not enjoy being over-watered, this will cause their leaves to droop, pale and turn yellow over time. They are also sensitive to fluoride, so filtered water is best. Alternatively, tap water can be left to sit for a couple of days, which allows these harmful chemicals to dissipate.
This plant does not like direct sunlight, as this can scorch the leaves and dry out its flowers. Near a window but not directly in it, in a warm room will be fine and it’s best to avoid draughts or placing it next to a radiator. Peace Lilies can also tolerate lower light levels, so are the perfect plant to brighten a dark corner but are likely to produce more flowers in a lighter spot.
