Peace Lily Care

The Peace Lily, known for its lush foliage and white blossoms, is a popular indoor plant that brings a touch of serenity to any space. Its care is straightforward, making it a favorite among both green thumbs and beginners. By understanding and meeting its basic needs, you can keep your Peace Lily thriving. In this article, you’ll learn how to best care for this beautiful plant.

Scientific Classification

Plants are sorted into groups based on their features. This system helps us understand how plants are related. The Peace Lily is one kind of plant, and scientists have given it a special name. Here’s how it fits into the plant world:

  • Kingdom: Plantae
  • Division: Angiosperms
  • Class: Monocots
  • Order: Alismatales
  • Family: Araceae
  • Genus: Spathiphyllum
  • Species: Spathiphyllum spp.


For your Peace Lily to thrive, it needs the right amount of light. However, it doesn’t like direct sunlight. Instead, it prefers bright, indirect light. Think of a spot near a window, but not in the direct path of the sun’s rays. Too much direct sun can burn its leaves, causing brown spots. If it’s too dark, your Peace Lily might not bloom. The best balance is a place where daylight is present for several hours, but where the sun doesn’t hit the plant directly. If you see the leaves turning yellow or brown, that might be a sign of too much light. On the other hand, if the Peace Lily is not flowering and has leggy stems, it probably needs more light. Remember, gentle morning light is better than harsh afternoon sun.


When you care for a Peace Lily, you give it just enough water. It likes its soil moist, but not soggy. Water the plant when the top inch of soil feels dry. Don’t wait too long, or the leaves might droop. Give it a good drink, allowing the water to sink down to the roots. Be careful not to flood the pot. Extra water should drain out so the roots don’t sit in water. This can cause root rot. If you touch the soil and it feels wet, wait a bit before watering again. Use room temperature water, as cold water may shock the roots. Keeping a balanced watering schedule helps your Peace Lily stay healthy and strong.


Soil is like a cozy bed for your Peace Lily’s roots. It needs to be just right for the plant to be happy and healthy. For your Peace Lily, you want soil that holds moisture but also drains well. This means the soil is wet enough to give the roots a drink, but not so wet that the roots sit in water. A good mix often includes peat, perlite, and vermiculite. These ingredients help balance moisture and air in the soil. If the mix feels heavy or clumpy, your Peace Lily may not grow well. Look for a potting mix that is labeled for indoor plants or specifically for Peace Lilies. You can find these at most garden centers. Remember, the right soil is key to keeping your plant strong and avoiding problems with water.


Peace Lilies prefer warm conditions typically found in your home. They thrive in temperatures between 65 and 80 degrees Fahrenheit (18 to 27 degrees Celsius). Keep them away from cold drafts and sudden temperature changes which can shock the plant. During the winter, be cautious not to place the Peace Lily near cold windows or doors. If the temperature drops below 45 degrees Fahrenheit (7 degrees Celsius), the plant may suffer. It’s crucial to maintain a stable environment to keep your Peace Lily healthy. Remember, a comfortable room temperature for you is likely suitable for your Peace Lily too.


Humidity is the amount of water vapor in the air. The peace lily loves humidity, similar to the moist environment of a rainforest. In your home, it thrives when the air is not too dry. When the humidity is low, the leaves may turn brown at the tips and edges. To keep your peace lily happy, you can mist its leaves with water. Another option is to place a tray with water and pebbles under the pot. As the water evaporates, it increases the moisture around the plant. You can also use a humidifier to add moisture to the air. During winter, when indoor air tends to be drier, pay extra attention to humidity levels. Your peace lily will show you it’s content with shiny, healthy leaves when the humidity is just right.


Fertilizer is like a vitamin boost for your peace lily. It gives your plant extra nutrients that it might not get from the soil alone. These nutrients are important for your peace lily to grow healthy and strong. You should use fertilizer sparingly, which means just a little bit every now and then. If you give your peace lily too much, you might harm it. It’s like eating too much candy; a little can be good, but too much is bad for you. You’ll want to fertilize your peace lily about once every six weeks in the growing season, which is spring and summer. But during the fall and winter, your peace lily doesn’t grow as much, so you don’t need to fertilize it during these times. Always follow the instructions on the fertilizer package to make sure you’re using the right amount.

Size & Growth Rate

A Peace Lily grows to a modest size indoors. On average, it can reach 1 to 4 feet in height and 1 to 3 feet in width. You will notice that it grows slowly. This is just how Peace Lilies are – they take their time. In the right conditions, it may grow faster, but it’s not a plant that will outgrow your space quickly. In a year, you can expect your Peace Lily to grow a few inches at most. Its growth rate depends on how much light, water, and care you give it. Remember, a happy Peace Lily will grow steady and strong. Even though it might be slow, watching your plant increase in size can be rewarding.

Common Issues

Taking care of a peace lily can be easy, but sometimes you may face problems. One common issue is yellow leaves. This often happens when you give your plant too much water. Brown leaf tips can mean you are underwatering your peace lily or it’s too dry in the room. If the leaves are droopy, this might be a sign that your plant needs water. Sometimes, pests like spider mites or mealybugs might attack your peace lily. They can cause damage and make the plant look unhealthy. If your peace lily is not flowering, it may not have enough light. Make sure you check your plant for these issues so you can keep it healthy and happy.


Toxicity refers to how poisonous a plant is to people or animals if they eat it. The Peace Lily is indeed a beautiful houseplant, but it contains compounds that are toxic when ingested. If you have a Peace Lily in your home, you should know that it can cause problems if a person or pet chews on or eats its leaves or stems. Some signs of Peace Lily toxicity include a burning sensation in the mouth, stomach upset, and sometimes even vomiting. Because these plants can harm pets, like cats and dogs, it’s essential to place your Peace Lily where they can’t reach it. If someone does accidentally eat part of a Peace Lily, they should get help from a doctor or vet right away. Always handle your Peace Lily with care to prevent any accidents.

Pro Tips

Caring for your Peace Lily doesn’t have to be tricky. Stick to these helpful hints to keep it thriving:
