Humidity, Fertilizing, and other Requirments

Peace lilies tend to enjoy high humidity, thus misting their leaves or placing them atop a moisture tray of gravel can help to increase humidity around the plant.

Moreover, these plants are not heavy feeders.

To encourage spring and summer growth, fertilize them every 6 weeks or so with a well-balanced houseplant fertilizer in late winter.

Peace lilies are tropical plants, so make sure to keep them at a temperature above 60°F (16°C) and away from cold, drafty windows.

Moreover, green flowers, weak-looking flowers, or a general lack of flowers can be due to improper fertilizing.

In the case of green flowers, cut back on fertilizing, as the plant may be getting too much nitrogen.

In case of weak-looking flowers or a lack of flowers, try to switch to a fertilizer that is especially for flowering plants.
