Can I leave my peace lily outside?

Peace lilies (Spathiphyllum) are typically grown as indoor houseplants because they are native to tropical rainforests and are sensitive to cold temperatures. However, they can be placed outside under certain conditions, but it’s important to be cautious and provide the right environment to prevent damage to the plant. Here are some guidelines for leaving your peace lily outside:

Season: Peace lilies are best suited to outdoor conditions during the warm spring and summer months when temperatures are consistently above 65°F (18°C). They should be brought back indoors when the weather turns cooler in the fall.

Light: Place your peace lily in a location with bright, indirect light. Avoid direct sunlight, as this can scorch the leaves. A spot with filtered sunlight, such as under a tree or on a covered porch, is ideal.

Can I leave my peace lily outside?

Temperature: Ensure that the outdoor temperature remains within the acceptable range for peace lilies, which is between 65°F to 80°F (18°C to 27°C). Sudden temperature drops, especially at night, can harm the plant.

Protection from Extreme Weather: If you experience heavy rain, strong winds, or unseasonably cold temperatures, it’s best to provide protection for your peace lily. Move it to a covered area or use an umbrella or plant cover to shield it from harsh conditions.

Container Gardening: If you have your peace lily in a pot, it’s easier to move it in and out as needed. Container gardening allows you to control its environment more effectively.

Pest Control: Monitor the plant for pests, as outdoor conditions may expose it to a greater risk of infestations. Treat the plant with natural remedies if necessary.

Regular Inspection: Regularly check the plant for any signs of stress, damage, or disease. Address issues promptly to prevent them from worsening.

Proximity to Water: Keep an eye on the watering needs of your peace lily. Outdoor conditions may require more frequent watering, but always ensure that the soil is well-draining and doesn’t become waterlogged.

Transitioning: When moving the plant outdoors, do it gradually. Start with a few hours of outdoor exposure and increase the time over several days to help the plant acclimate.

Bringing It Indoors: As temperatures drop in the fall, make sure to bring your peace lily back indoors before it gets too cold. Sudden cold snaps can damage or kill the plant.

While it is possible to place your peace lily outdoors during the warm season, it requires attentive care and protection to ensure its well-being. Be prepared to bring it inside if conditions become unfavorable, and always monitor the plant’s health to make any necessary adjustments.

Can I put my peace lily outside in summer?

Yes, you can definitely put your peace lily outside during the summer, and I’ve done this with mine to give it a bit of a change in environment. However, there are some important factors to keep in mind to make sure it thrives in an outdoor setting.

First, I always ensure the temperature stays within the peace lily’s preferred range, which is roughly between 65°F to 80°F (18°C to 27°C). These plants are sensitive to cold, so I make sure to bring it back inside if the temperature drops significantly, especially at night.

I place it in a spot with bright, indirect light. Peace lilies don’t like direct sunlight, which can scorch their leaves, so I usually choose a shaded area on my patio or under a tree. If it’s been indoors for a while, I gradually expose it to more outdoor light to help it acclimate.

It’s also essential to protect it from heavy rain and strong winds. I use a cover or bring it under a shelter during storms to avoid overwatering and damage to the leaves.

Lastly, I keep an eye out for pests, as outdoor conditions may attract them. Regular inspections and natural remedies help me ensure my peace lily stays healthy during its summer vacation outdoors.

What are the benefits of a peace lily?

Having a peace lily in my home has been a wonderful experience, and I’ve come to appreciate the numerous benefits it offers. Here are some of the advantages I’ve noticed:

  1. Air Purification: One of the standout benefits of a peace lily is its air-purifying properties. It effectively removes common indoor pollutants like formaldehyde, benzene, and ammonia. Breathing cleaner air in my living space has contributed to a healthier environment.
  2. Humidity Control: Peace lilies release moisture into the air through a process called transpiration. This has been especially helpful in maintaining a more comfortable humidity level in my home, preventing issues like dry skin and respiratory discomfort.
  3. Aesthetic Appeal: With its elegant, glossy green leaves and occasional white blooms, the peace lily adds a touch of natural beauty to my living space. Its graceful appearance enhances the ambiance and makes any room more inviting.
  4. Low Maintenance: Peace lilies are relatively low-maintenance houseplants. They don’t require a lot of attention, and as long as I keep their basic needs met, they thrive without much effort on my part.
  5. Easy to Grow: Even for someone like me without a green thumb, peace lilies are forgiving and easy to grow. They’re a great choice for beginners in the world of indoor gardening.
  6. Symbolic Meaning: Beyond the physical benefits, the peace lily has symbolic significance as a representation of peace and purity. Having it in my home is a reminder of those qualities, creating a calming and serene atmosphere.

Incorporating a peace lily into my living space has improved the air quality, added aesthetic charm, and brought a sense of tranquility to my home. It’s a plant I highly value for its multiple benefits and easy care.

How cold is too cold for a peace lily?

A peace lily (Spathiphyllum) is a tropical plant that is sensitive to cold temperatures. Ideally, it should be kept in an environment with temperatures between 65°F to 80°F (18°C to 27°C). When the temperature drops below this range, the peace lily can become stressed, and prolonged exposure to colder conditions can lead to damage or even death.

Generally, temperatures below 50°F (10°C) can be too cold for a peace lily. If the plant is exposed to such cold temperatures, it may show signs of distress, including wilting, yellowing leaves, and slowed growth. Frost or freezing temperatures are particularly harmful and can lead to irreversible damage.

To protect your peace lily from the cold, it’s essential to bring it indoors when the outdoor temperatures are consistently below 50°F. If you plan to place it outside during the warm summer months, be prepared to bring it back indoors before the arrival of cooler fall temperatures. Additionally, avoid placing it in areas with drafts or near cold windows during the winter months to prevent temperature stress.

Where is the best place to put a peace lily in the winter?

During the winter, I’ve found that the best place for my peace lily is indoors in a location that offers the right combination of light, temperature, and humidity to ensure its well-being. Here’s where I typically place my peace lily during the colder months:

  1. Bright, Indirect Light: I position my peace lily near a north or east-facing window where it can receive bright, indirect light. These directions provide gentler sunlight that’s less likely to scorch the leaves, which is especially important during the winter when the sun can be harsh.
  2. Protection from Drafts: I make sure to keep the plant away from drafts, such as those from windows, doors, or heating vents. Sudden temperature changes and cold drafts can stress the peace lily, so I ensure it’s in a stable, draft-free location.
  3. Consistent Temperature: I maintain a consistent indoor temperature range of 65°F to 80°F (18°C to 27°C). This is the ideal range for peace lilies, as they are sensitive to cold temperatures. Avoid placing it in areas with fluctuating temperatures.
  4. Humidity: To maintain adequate humidity levels, I use a humidifier in the room where the peace lily is situated. Dry indoor air can be a challenge during the winter, and peace lilies appreciate higher humidity.
  5. Avoid Overwatering: During the winter, I adjust my watering routine. I make sure the soil remains consistently moist but not waterlogged. I let the top inch of soil dry out before watering to prevent overwatering in the lower light and cooler conditions.

Are peace lilies poisonous to dogs?

Yes, peace lilies (Spathiphyllum) are considered toxic to dogs. Peace lilies contain calcium oxalate crystals, which can cause various symptoms if ingested by dogs. These symptoms may include:

  1. Mouth and Throat Irritation: Chewing or biting into the plant can lead to irritation, drooling, and pawing at the mouth.
  2. Gastrointestinal Distress: Ingesting any part of the peace lily can lead to symptoms like nausea, vomiting, diarrhea, and abdominal pain.
  3. Respiratory Issues: If a dog inhales pollen from the peace lily, it can irritate the respiratory system, causing coughing or difficulty breathing.

It’s essential to be aware of the potential danger of peace lilies if you have dogs in your home. If you suspect that your dog has ingested any part of a peace lily, contact your veterinarian or an emergency pet poison hotline immediately. They can provide guidance on the necessary steps to take and whether medical intervention is required.

To keep your dog safe, it’s a good idea to place peace lilies and other toxic plants out of their reach or choose non-toxic houseplants for your home.
