Essential Tips for Caring for Peace Lilies: Everything You Need to Know


The peace lily (Spathiphyllum spp.) is a popular indoor plant that is frequently gifted and admired for its beautiful white flowers. Although they are relatively easy to care for, peace lilies do require some attention to keep them healthy and thriving.

When it comes to planting peace lilies, it’s important to choose a pot that has drainage holes to prevent water from pooling at the bottom. The peace lily prefers to be kept moist but not overly wet, so make sure to water it regularly. However, be careful not to over-water, as this can lead to root rot and fungal problems.

Fertilizing the peace lily is also important for its growth and overall health. Using a balanced, water-soluble fertilizer can help promote healthy foliage and vibrant flowers. Dilute the fertilizer and feed the plant every two to four weeks during the growing season.

One common issue that peace lily owners may notice is browning or yellowing leaves. This can be related to over- or under-watering, low humidity, or even direct sunlight. To keep your peace lily healthy, it’s important to track its waterings and ensure it is receiving the right amount of light.

Although peace lilies are generally hardy plants, they can be prone to fungal problems. If you notice any fungal growth on the leaves or in the soil, remove the affected parts and treat the plant with a fungicide. Additionally, keeping the leaves clean and dust-free can help prevent fungal issues.

In summary, peace lilies are beautiful indoor plants that require regular care and attention. By properly watering, fertilizing, and monitoring for any potential issues, you can help your peace lily thrive and enjoy its many benefits.

The Truth About The Peace Lily

The peace lily, also known by its scientific name Spathiphyllum, is a popular indoor plant that is cherished for its beautiful white flowers and lush green foliage. However, keeping a peace lily healthy and beautiful requires proper care and attention. In this article, we’ll dive into the best practices for maintaining the health and beauty of your peace lily.

1. Watering

Proper watering is crucial for the well-being of your peace lily. The peace lily prefers evenly moist soil, but it’s important not to overwater it. Allow the top inch of soil to dry out before watering again. Additionally, excessive waterings can lead to root rot and fungal issues. So, make sure to water your peace lily in moderation.

2. Light

Peace lilies thrive in bright, indirect light. They can tolerate lower light conditions, but their growth and flowering may be negatively affected. Avoid placing your peace lily in direct sunlight, as this can scorch the leaves.

3. Fertilizing

Peace lilies don’t require frequent fertilizing, but they do benefit from occasional feedings. Use a balanced liquid fertilizer diluted to half strength, and apply it every 4 to 6 weeks during the growing season (spring and summer). Be careful not to overfertilize, as this can cause fertilizer burn and damage the roots.

4. Troubleshooting

If you notice the leaves of your peace lily turning yellow, it may be a sign of overwatering or underwatering. Adjust your watering routine accordingly. Moreover, peace lilies are prone to pests like aphids and spider mites. Keep an eye out for any signs of infestation and take necessary steps to control them. If you find fungus gnats, you can use sticky traps or natural alternatives like diluted neem oil to get rid of them.

5. Repotting and Propagation

Peace lilies prefer slightly crowded roots, so there’s no need to rush into repotting. However, if your peace lily outgrows its pot or the soil becomes overly compacted, it’s time to repot. Use a well-draining potting mix and move your peace lily into a slightly larger pot. Propagation can be done by dividing the plant during repotting or by taking leaf or stem cuttings.

In conclusion, keeping a peace lily healthy and beautiful can be achieved by providing the right amount of water, light, and fertilizers. Additionally, staying vigilant about pest control and occasional repotting will help promote its growth and blooming. By following these guidelines, you can enjoy the beauty of your peace lily for years to come.

Care of Peace Lilies

Peace lilies are beautiful and popularly growing indoor plants that require minimal care. They are also known as Spathiphyllum or Closet Plant. In order to keep your peace lily healthy and thriving, here are some care tips:

1. Watering: Peace lilies like to be kept moist, but not soaking wet. Water them frequently, but make sure the soil has drained properly before watering again. It’s best to water with a liquid fertilizer diluted in water, as it provides essential nutrients for the plant.

2. Light: Peace lilies prefer bright, indirect light. They can tolerate low light conditions, but too much direct sunlight can harm the leaves. Place them in a location where they get filtered sunlight throughout the day. If you want to keep your peace lily outside, make sure it is in a shady spot.

3. Fertilizing: Peace lilies don’t require a lot of fertilizers, but a slow-release balanced fertilizer can be applied once every few months. Dilute the fertilizer according to the instructions on the packaging, as too much fertilizer can cause leaf burn. Always fertilize during the growing season to promote healthy growth.

4. Repotting: Peace lilies don’t need to be repotted frequently. Generally, repotting is only needed when the roots have filled up the pot or when the plant is becoming rootbound. Use a well-draining soil mix and a pot that is slightly larger than the current one.

5. Troubleshooting: Peace lilies are relatively pest and disease-resistant, but there are a few common problems you may encounter. Fungal diseases can occur if the plant is overwatered or if there is poor air circulation. To prevent this, make sure the lily gets enough air circulation and water it from the bottom. If you spot any signs of pests, such as spider mites or mealybugs, treat them immediately with an appropriate pesticide.

By following these care tips, your peace lilies will continue to be a beautiful addition to your indoor or outdoor environment.


Watering is an essential part of the care for peace lilies. These plants thrive in moist conditions, so it’s important to keep the soil consistently hydrated. Here are some guidelines to follow:

  • Water your peace lily about once a week, or whenever the top inch of soil feels dry to the touch. Take care not to over-water, as soggy soil can lead to root rot.
  • When watering, use room temperature water. Cold water can shock the plant’s roots, while hot water may scorch them.
  • Avoid using chlorinated water, as it can cause browning of the leaf tips. If you don’t have access to filtered water, let tap water sit out overnight to allow the chlorine to dissipate.
  • Make sure to water the soil directly rather than the leaves, as wet foliage can attract pests and cause fungal issues.
  • Using a watering can or spray bottle with a narrow spout can help control the flow of water and prevent over-watering.
  • Pay attention to the color of the leaves. If they become droopy or start to turn brown, it may be a sign that the plant is not getting enough water. On the other hand, yellow leaves can indicate over-watering.
  • If you see any pests, such as gnats or whiteflies, on your peace lilies, it may be a sign of over-watering. In this case, cut back on watering and make sure the soil has a chance to dry out between waterings.

In addition to regular waterings, peace lilies benefit from occasional fertilizing. However, it’s important not to over-fertilize, as this can cause salt buildup and damage the roots. Follow the instructions on the fertilizer packaging, and use a balanced liquid fertilizer with a ratio of 20-20-20 or similar. Apply the fertilizer every 2-3 months during the growing season (spring and summer), and reduce or stop fertilizing in the winter when growth slows down.

If you notice that your peace lily has outgrown its current pot or the soil is not retaining moisture as well as it used to, it may be time to repot. Choose a pot that is 1-2 inches larger in diameter than the current one and use a well-draining potting mix. Gently remove the plant from its current pot, loosen the roots, and place it into the new pot. Backfill with fresh potting soil and water thoroughly.

Remember to keep your peace lilies away from pets, as they can be toxic if ingested. If you have any concerns about your pet’s safety around the plant, it’s best to consult a veterinarian.

Closing thoughts: Watering is a crucial aspect of peace lily care. By following these guidelines and paying attention to your plant’s needs, you can help it thrive and live a long, healthy life.


Peace lilies are not heavy feeders, so they don’t require a lot of fertilizing. However, adding a bit of compost to their soil every 5 to 7 weeks can help keep them healthy and promote better growth. A balanced, all-purpose fertilizer with an NPK ratio of 5-2-2 is an excellent choice for indoor peace lilies.

When fertilizing peace lilies, dilute the fertilizer in water according to the instructions on the packaging. It’s important not to apply the fertilizer directly onto the leaves or directly above the roots, as it can cause burning and damage. Instead, pour the diluted fertilizer solution onto the soil, making sure it is evenly distributed.

Over-fertilizing peace lilies can lead to excessive foliage growth and decreased blooming. If you notice that your peace lily is growing a lot of green leaves but not producing many flowers, try reducing the frequency of fertilizing or using a weaker dilution.

Peace lilies are generally low-maintenance plants, but they can be susceptible to certain pests and diseases. Fungal diseases are a common issue associated with peace lilies, as they prefer environments with high humidity. To prevent fungal infections, it’s important to keep the leaves dry and avoid over-watering. If you notice any signs of fungal growth, such as browning or spotting on the leaves, move the peace lily to a drier location and improve air circulation around the plant.

In addition to its beautiful foliage, peace lilies are also an excellent air purifier, as they can remove certain toxins like formaldehyde and benzene from the environment. However, they are not the best plants for houses with pets or small children as peace lilies can be toxic if ingested. If you have curious pets or children, it’s best to keep peace lilies out of their reach or choose non-toxic plants instead.

If you follow these care instructions, your peace lily will continue to bring you joy with its lush green leaves and occasional white blooms. Just remember to water them regularly, fertilize every 5-7 weeks, and keep an eye out for any signs of pests or diseases. With these simple steps, your peace lily will thrive and make a beautiful addition to your home or office.
