Potting-mix: For potting mix a composite of Garden soil, Perlite & sand is ideal. One can add little coco peat. Natural fertilizer of leaves called humus is also useful for the plant. It loves drained soils.
Watering: Every 2-3 days during summers and once a week in winter is ideal. Use filtered water, Keep the soil moist, but do not overwater. It is a chemical sensitive plant, such as tap water, such as fluoride, which may cause brown leaf tips. Use filtered, room-temperature water, if possible. Peace lilies enjoy high humidity. To increase humidity in the plant moistened tray can be used. The main issue in this plant is overwatering & roots tend to rot. Give water when leaves start to droop. Under-watering is ok, but root should not become warm, Brown leaf tips mean overwatering & yellow leaf indicates under-watering.
Lighting: Place pot in indirect sunlight. Very well known as a tropical plant, so keep them in temperatures above 60 °F (16 °C) and away from cold, drafty windows. They do best in temperatures upwards of 70 °F (21 °C). Keep away these plants reach out of direct afternoon sunlight but in a well-lit area. Facing towards the east window is ideal for the plant, as they will be exposed to the warmth of the morning sun but avoid the intensity of mid-day rays. So for best growth, they can be kept either on the east or northeast facing balconies or indoors for 15 days and outdoor in shade for 2-3 days.
Propagation: A single peace lily root can translate to multiple roots and stem plants within a year. It can be thus separated out and planted for propagation.
Fertilization: Occasionally. 20:20:20 NPK fertilizer once every 6 weeks during winter, once during summer. These are not heavy feeders, so fertilize only occasionally. 20:20:20 NPK fertilizer of 1/4 spoon in 1 liter should be given once in 6 weeks during blooming season i.e. spring and early summer.
Flower Growth: For flower growth normally nurseries give Gibberellic acid which is a plant hormone. They grow flowers only when matured. In the house, one can keep in the low-light area (Light just enough to read a book) for 2 days so that the hormone is produced naturally. This helps in flower growth. If spathe or flower starts blooming green it means over-fertilization.
