|The Peace Lily plant|
Tip: if nothing works try this it definately works! Feed your peace lily plant with food and egg shells. If the leaf tips are turning yellow then it is having too much sun exposure and if the leaves are droppring then maybe less or more water is the reason. In my case there was less exposure of sun. For flowering any plant requires some amount of sunlight though not direct as it will result in leaf burn. Even if you have your palnt indoors, or in the office remember the air conditioner air is not very good for your peace lily plant. Try to give it soem fresh air and sunlight at regualr intervals to keep the peace lily plant healthy.
