How to Grow and Care for Peace Lilies

Peace Lily Care

    • How often, and how many, white flowers a peace lily plant produces will vary based on things such as soil, fertilizer, lighting, and temperature.
    • While some rarely produce the lovely white-cupped and spade-shaped flowers, others may consistently have several of them at a time. Some may only produce one at a time.
  • The Peace Lily plant grows in dark places – This isn’t completely wrong, but it’s a misleading myth.

Many plants will be reasonably happy in darker places but this is ultimately confusing a surviving plant with one that would positively thrive in different conditions.

  • Peace lilies do not require a lot of suns to be happy. Most do best in indirect sunlight. They do well in temperatures ranging from 65 to 80 degrees Fahrenheit. Peace lilies do not like wet feet, which is to say, they do not do well if their roots are left in standing water.
  • They do like consistently moist soil, however. This means that their watering needs can be met every week or so, and possibly more in hotter temperatures.
  • These plants are very forgiving if watering times have been forgotten. They are great at conveying when it is past time for water because they will begin to droop down until they have been watered again. After being watered, they perk back up once more as happy as ever, instantly forgetting that they were momentarily forgotten.RELATED: Non-Toxic Bathroom Plants

Peace Lily Size

They can be found in a wide array of sizes ranging from 15 inches to 6 feet tall. These are different varieties. For example, on the small end of only a few inches tall, there is the “Power Petite” and the “Wallisii.” The larger variety that can grow up to several feet can be found under the name of “Sensation.” For a medium-sized peace lily, one might look for the “Mauna Loa Supreme” or the “Clevelandii.” These grow to an average height and width of about 3 feet.

As far as toxicity goes, peace lilies are only mildly toxic to animals and humans if ingested. This means that they may cause an upset stomach, a burning sensation in the mouth, or cause difficulty swallowing. This is certainly unpleasant but not deadly. Because these are not true lilies, they do not contain the toxins that are found in true lilies that cause kidney failure in cats and some other animals.

The interesting thing about peace lilies

Another interesting thing about peace lilies is that they are natural air purifiers. At the time of this writing, they are number 4 on the list of air-purifying plants on the NASA Clean Air Study Wikipedia page. How many of each plant is needed to successfully clean the air of toxins in a room is not mentioned. This would likely depend on each plant’s size, the size of the room, and the level of particles in the air. Further research is recommended if this is why you’re purchasing a peace lily.

Overall, this is a beautiful plant, that even when not flowering, is gorgeous with its dark leafy green leaves. It can be found in all sizes to suit any location, does not require a lot of attention, does well in lower-lit areas, and may help clean the air all the while looking fabulous.

Troubleshooting Problems with Peace Lilies

Peace lily concern tends to be pretty straightforward, but you might regard a few issues with these plants. Keep an eye out for:

• Fungus gnats. As discussed above, if you grow peace lilies in Miracle-Gro® Indoor Potting Mix, this is less likely to be an issue. But if you’re starting in a different type of potting soil, you may need to fight this battle. First, try watering less regularly and make sure the tip of the soil dries out among waterings. If that doesn’t work, you may need to use Bt (Bacillus thuringiensis, an insecticide for home garden use) to destroy the larvae in the soil.

• Yellow leaves. Older leaves on peace lilies will become yellow with age. Separate them, cutting all the way at the center of the plant. Let the soil dry out a bit and cut back on watering, and the plant may recover.

• Brown edges. This is usually a sign that your peace lily has been getting direct sunlight. If that’s the case, move the plant out of sunbeams. You can also try elevating the humidity around your plant. Fill the saucer that goes under the pot with small pebbles. Add water, up to about 1/3 inch below the top of the stones. The water will evaporate up around the leaves, raising the humidity.
