Peace lily care indoors

Peace lilies are known for their low-maintenance nature, making them popular with gardeners of all skill levels. Here are some tips to get the most out of your plant.

Sunlight needs for spathiphyllum

Peace lilies prefer bright, indirect light but can tolerate low-light conditions. Placing them near a north or east-facing window is ideal.

I have my plant situated below a window on the floor in a north facing window and it has adapted well to this spot.

Be careful of too much sun, since direct sunlight can scorch their leaves. They thrive in temperatures ranging from 65°F to 80°F (18°C to 27°C) and prefer slightly humid environments.

Misting will help to keep the plant happy. I bring my peace lily outdoors in the summer time. It seems to benefit from time outside in the shade with my hostas.

You can grow it outdoors all year long in the warmer zones –  zones 10 and 11. If your temperatures are colder than this in the winter, spathiphyllum is best grown as an indoor plant.

Watering requirements for peace lily indoors

Maintaining the right moisture level is important for peace lilies. While they enjoy slightly moist soil, overwatering can lead to root rot.

A good practice is to water the plant when the top inch of soil feels dry to the touch. Be sure to allow excess water to drain from the pot.

Remember to empty the saucer to prevent the plant from sitting in water. My plant sits in a decorative outer sauce and I make sure to empty this after the water has drained out.

Fertilizing and soil needs for peace lily care indoors

When it comes to potting your peace lily, choose a container with drainage holes to prevent the soil from staying too wet. Peace lilies prefer well-draining potting mix rich in compost or other organic matter.

A typical mix consists of equal parts peat moss, perlite, and pine bark. Repotting when the plant outgrows its container helps maintain healthy growth. However, peace lilies seem to do best when they are slightly pot bound.

The ideal pH is 6.0 to 7.0 (slightly acidic to neutral.)

During the growing season, spring to early fall, feed your peace lily with a liquid fertilizer diluted to half-strength once a month. You do not need to fertilize the plant during the winter.

Can peace lilies be grown in water?

Yes, peace lilies can grow in water alone, although they typically prefer soil-based growing mediums. You will sometimes see them for sale in vases without any soil.

If you grow them this way, the plant should be suspended above the water line if possible to allow only the roots to grow down into the water but keeps leaves from being constantly wet, which can cause rot.

Growing peace lily in water is referred to as hydroponics or water culture. 

Flowers and foliage of peace lilies

One of the best things about peace lilies is that both the blooms and the foliage are very attractive!

The foliage of spathiphyllum is characterized by lush, glossy green leaves, which emerge from a central point and fan outwards. The leaves are typically long, and lance-shaped, with prominent veins running through them, adding to their visual appeal.

Peace lily foliage has a graceful, arching habit and a shiny surface which reflects the light.

The NASA clean air study has shown that the leaves of peace lily, as well as parlor palm, and several other plants are considered air purifying plants.

Peace lily blooms are characterized by their pristine white color and distinctive spathe-and-spadix structure.

The spathe, often mistaken for a petal, is a modified leaf that wraps around the spadix, a central spike containing tiny, densely packed flowers.

One of the remarkable features of peace lily blooms is their longevity. Under the right conditions, each flower can last several weeks to months, providing continuous beauty throughout the blooming season.

As the blooms age, they gradually turn green, adding a unique charm to the plant.

Peace lily maintenance indoors

Regular pruning helps keep your peace lily looking tidy and encourages healthy growth. Remove yellowing or dead leaves promptly to prevent the spread of disease.

Wipe the leaves occasionally with a damp cloth to remove dust and maintain their glossy appearance.

Diseases and insects

Peace lilies are relatively resistant to pests and diseases. Occasionally, they may encounter issues such as scale and mealybugs, spider mites, aphids, or leaf spot diseases.

However, these problems are usually minor and can be addressed with simple preventive measures or treatments.

Gently separate the plant into smaller sections, ensuring each division has roots attached. Plant them in separate containers with fresh potting mix, and keep them moist until new growth appears.

Is peace lily poisonous?

Spathiphyllum spp. is known to be quite toxic to pets and mildly toxic to humans. Like dieffenbachia, peace lily plant contains insoluble calcium oxalate crystals that are released when the plant is chewed and can cause oral pain, drooling, vomiting or diarrhea.

Very rarely swelling in the mouth may lead to difficulty breathing. For these reasons, take care to keep your plant away from kids and pets.
