Tips for Care - Peace Lily (Spathiphyllum)
The peace lily is an elegant low-maintenance indoor plant, which is suitable for both home & office. It enhances the beauty of the space, brings peace and prosperity, and purifies the air. It is one of the few flowering indoor plants, which flowers during early summer. The flowers are leaves or spathes enclosed in a white leafy structure, hence the name Spathiphyllum.
Potting- For potting-mix use a composite of Garden soil, Perlite & sand is ideal. One can add little coco peat. Natural fertilizer of leaves called humus is also helpful for the plant. It loves drained soils.
Watering Requirement - Every 2-3 days during summers and once a week in winters is ideal. Use filtered water; keep the soil moist, but do not overwater. Peace lilies can tolerate short periods of dry soil. Peace lilies are sensitive to chemicals commonly found in tap water, such as fluoride, which may cause brown leaf tips. Use filtered, room-temperature water, if possible. Peace lilies enjoy high humidity. Misting their leaves or placing their pot atop a moistened tray of gravel can help to increase humidity. The main issue in this plant is overwatering & plant roots tend to rot. Give water when leaves start to droop. Under-watering is ok, but the root should not become warm. Brown leaf tips mean overwatering & yellow leaf indicates under-watering.
Light Requirement – Indirect Sunlight. Peace lilies are tropical plants, 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 these plants out of direct afternoon sunlight but in a well-lit area. An east-facing window is ideal, 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 the shade for 2-3 days.
Propagation – A single peace lily root can translate to multiple stem plants within a year. It can be thus separated and planted for propagation.
Fertilization - Occasionally. 20:20:20 NPK fertilizer once every six weeks during winter, once during summer. Peace lilies are not heavy feeders, so they 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, nurseries usually give Gibberellic acid, which is a plant hormone. They grow flowers only when they mature.
In the house, one can keep in a low light area (Light just enough to read a book) for two days so that the hormone gets naturally produced. This helps in flower growth. If Spathe or flower starts blooming green, it means over-fertilization.
