Peace Lily Culture


FYI - The peace lily is one of the Top 10 houseplants tested for removing toxic chemicals from homes and offices.

Botanical Information -

The “Peace Lily” is such a popular indoor houseplant… but where does the Spathiphyllum come from, what other plants is it related to and more.

Potting

Spathiphyllum as with most tropicals will flourish in almost any well drained soil. Most growers use a mixture containing peat moss, bark and sand. The majority of plants grown are in 6″, 8″, 10″ and 14”. Some varieties such as “Sensation” can reach a height of 6 feet and have an equal width. Today, most plants are produced from tissue culture or clones.

Water

Depending on the indoor environment watering should be weekly. Many people overwater the plant keeping the soil soggy. Soil should be kept moist but not soggy. The soil should dry out between waterings. Excessive drying out can cause the plant to wilt and yellowing of leaves and edges. When watering use water that is at room temperature. City water to sit to allow chlorinating to evaporate. Spathiphyllum grow very well with sub-irrigation, visit Everlife for more information on sub-irrigation and take the headaches out of watering you plants.

Light

Spathiplyllum will survive low interior light but would prefer bright filtered light. Position dracaenas near or opposite a curtained southern window. Spathiphyllum has been used by interior plantscapers for many years as a ground cover where the light is very low. Spathiphyllum should NOT be placed direct sun or it will sunburn.

Fertilizer

When grown indoors spathiphyllum have most no need to be fertilized. If you must fertilize any well balanced fertilizer such as 20-20-20 will maintain growth. Pelleted fertilizers also work read instructions carefully. Indoors plants grow slower and therefore have lower requirements for food. If you are going to fertilize use approximately at 1/4 recommended strength. Over fertilizing can produce burning of tips and roots.

Temperature

Spathiphyllums enjoy warm conditions between 68-85 daytime temperature and prefer and 10 degree drop at nighttime. Cold, and drafty conditions in the 40′s and 50′s will slow growth considerably. Extended periods below 40 can damage leaves, stems and roots.

Humidity and Air Circulation

Humidity above 25-30% is best but will tolerate long periods down to 10-15%.

Pest and Disease

One of the great benefits of using Spathiphyllum inside is that they have few pest problems. Mealy bugs are probably the most common insect indoors. Most problems occur on the growing end when liners are first planted. Root and stem diseases are the most common problem and this is usually associated with over watering. Because of the wide leaves that most spathiphyllums have cleaning the leaves regularly with a damp cloth to remove dust will help not only in appearance but also in removing of pest which tend to gather under the bottom of leaves.

Propagation

Plants are usually grown from “liners” which have been produced from tissue culture and placed into trays. These liners are then planted into larger containers in a well drained soil. Fertilizer is not applied until after roots have been produced. Do not over pot.
