How to Grow and Care for Spathiphyllum Green Peace Lily

0 Comments

Green Peace Lily, scientifically known as Spathiphyllum, hails from the lush tropical rainforests of Colombia and Venezuela, nestled within the diverse ecosystems of South America. This plant earned its common name, "Peace Lily," due to the resemblance of its white flowers to the traditional symbol of peace. The name "Spathiphyllum" is derived from the Greek words "spath" meaning spathe and "phyllon" meaning leaf, referring to the characteristic leaf-like bracts that surround the flowers.

Peace Lily has lush, deep green foliage. The leaves are typically broad and lance-shaped, providing a rich backdrop and creating a delightful contrast to its flowers. Peace Lily is among the most popular flowering plants. The blooms are very long-lasting and typically remain vibrant for several weeks.  Additionally, the flowers have a unique quality of gracefully fading rather than wilting, maintaining their charm even as they age. This longevity makes Peace Lily a favorite choice for those seeking enduring floral displays that require minimal maintenance. 

 As for its growth habit, Peace Lily typically forms a dense, upright clump of foliage. This growth habit gives the plant a robust and compact appearance, making it a wonderful choice for both tabletops and floor displays.

Spathiphyllum Peace Lily is not just a beautiful flowering houseplant; it's also known for its air-purifying abilities. The Peace Lily is among the top air-purifying plants on NASA's list, thanks to its capacity to remove common indoor pollutants from the air. This plant can effectively filter out toxins like formaldehyde, benzene, and ammonia, contributing to a cleaner and healthier indoor environment. Its lush green leaves and white blooms are more than just decorative; they also work to improve the air quality in your home or office. This dual function of beauty and air purification makes Peace Lily a popular choice for any indoor space.

Can Peace Lily Tolerate Low-Light?

Peace Lily, is an ideal houseplant for low-light environments. While it can thrive in bright, indirect light, it also does well in areas with less sunlight. This adaptability makes it a popular choice for spaces with limited natural light, like offices, hallways, or rooms with small windows. They can maintain their lush green foliage even with minimal sunlight, though their flowering may be less frequent in darker spaces. If you have a room with a window that doesn't get much direct sun, or if you prefer to keep the blinds closed for most of the day, a Peace Lily will still flourish. However, it's essential to ensure that your Peace Lily gets some light, even if it's indirect or filtered, to maintain its health. Total darkness or overly dim environments can cause the plant to struggle. Regular care with proper watering and occasional feeding will keep your Peace Lily thriving, even in low-light settings.

Is Peace Lily Toxic?

Peace Lilies Spathiphyllum are attractive houseplants with elegant white blooms, lush foliage, and incredible air-purifying qualities. However, they contain calcium oxalate crystals, which can be toxic to humans and pets. Ingesting any part of the plant can cause oral irritation, gastrointestinal distress, and, in severe cases, respiratory issues. Pets, particularly cats and dogs, can also exhibit symptoms like excessive drooling, vomiting, and difficulty swallowing. To avoid these risks, keep Peace Lilies out of reach of children and pets, using plant stands or hanging planters to create safe boundaries. If exposure occurs and you notice any unwanted symptoms, seek medical or veterinary attention immediately. With the right precautions, you can enjoy the beauty of Peace Lilies while minimizing potential harm.

General Care

Lighting

Peace Lily is very versatile when it comes to lighting. This plant thrives in low to medium light conditions, making it ideal for indoor environments where bright sunlight is limited. It can grow quite well in areas with indirect or filtered light, such as near a north-facing window or in a room with diffused sunlight. However, while Peace Lily can tolerate low light, it grows best with moderate to bright indirect light. This allows them to produce more flowers and maintain vibrant green leaves. Direct sunlight, especially from a south-facing window, can cause the leaves to scorch and develop brown tips or edges, so it's best to avoid placing them in direct sunlight for extended periods. 

If you do not have enough natural light in your room,  consider using a grow lamp, as prolonged periods in extremely low-light conditions can make your Peace Lily experience stunt growth and reduce their resilience to pests and diseases. 

Watering

This plant likes its soil consistently moist but not soaking wet or waterlogged. The key is finding the right balance to avoid under- or overwatering. Typically, water your Peace Lily when the top inch or two of the soil feels dry to the touch, which often means watering once every 5 to 7 days. The exact frequency can vary depending on the season, indoor temperature, and humidity levels. When you do water, make sure to do so thoroughly, allowing water to drain out from the bottom of the pot. This way, you ensure the entire root system gets hydrated without leaving the plant sitting in water, which can lead to root rot.

Good drainage is crucial, so make sure the pot has proper drainage holes. If water sits at the bottom, it can cause the roots to rot, leading to yellowing leaves and other health issues. While overwatering can be a common issue, causing yellowing leaves and root rot, under-watering can lead to drooping or wilting. If you notice these signs, adjust your watering habits accordingly. 

Soil And Fertilizer

Peace Lily thrives in well-draining soil that retains some moisture but doesn't get soggy. A standard houseplant potting mix usually suits it well, but adding some perlite or coarse sand can improve drainage, which is essential to prevent root rot. The soil should be light and airy to ensure that the roots can breathe, promoting the plant's health.

As for fertilization, the Peace Lily is not a particularly heavy feeder but does benefit from occasional feeding during its active growing season, which typically occurs in spring and summer. A balanced liquid fertilizer, diluted to half-strength, works well for this plant. Apply the fertilizer every 4 to 6 weeks during this period to support blooming and overall growth. It's crucial to avoid over-fertilizing, as this can lead to a buildup of salts in the soil, causing leaf burn or other damage. If you notice a white crust on the soil's surface or around the pot's edges, it could be a sign of salt buildup, indicating that the soil might need to be flushed with water to remove the excess. During the dormant months in fall and winter, the Peace Lily's growth slows down, so you should reduce or stop fertilization during this time.

Temperatures And Humidity

Peace Lily thrives in most indoor temperatures, typically between 65 and 80 degrees Fahrenheit. It doesn't handle cold weather well, so you should keep it away from drafts and temperatures below 40-50 degrees Fahrenheit, which can cause stress and potentially damage the plant.

When it comes to humidity, Peace Lily prefers a more humid environment, mimicking its natural tropical habitat. It does well with humidity levels of around 50% or higher. If the air in your home is too dry, the plant's leaves might start to brown at the edges, indicating that it needs more moisture in the air. To increase humidity, you can use a humidifier or place the plant on a tray filled with pebbles and water, ensuring that the bottom of the pot doesn't sit directly in the water. It's also a good practice to you’re your Peace Lily occasionally, especially during dry seasons or in heated indoor environments, which can drop the humidity levels. Please note that that while it appreciates humidity, overwatering should be avoided, as this can lead to root rot and other issues.

Extra Care

Potting And Repotting

Choosing a pot that has good drainage is utmost important for any houseplant. We recommend pots made from a porous material like cement, ceramic, or terracotta. These materials allow the roots to breathe and promote good airflow. Moreover, good pots should have one or several drainage holes to prevent water from sitting at the bottom, which can lead to root rot.

To repot a Peace Lily, gently remove it from its current pot, being careful not to damage the roots. If the roots are tightly wound or circling the pot, it's helpful to gently tease them apart to encourage outward growth in the new container. Choose a pot that's one size larger as big pot can cause overwatering problems. After repotting, keep the plant in a slightly shaded area to help it adjust to its new environment. Make sure your plant is not exposed to drafts or extreme temperatures, and avoid fertilizing for at least a month to let it recover from the shock of repotting. This process will help maintain the plant's health and encourage steady growth.

Pruning

Pruning is an essential part of your care routine for Peace Lily.  Begin by removing any yellowing or dead leaves. These are typically found at the base of the plant. Carefully cut them off at the point where they meet the stem or soil. If the plant has finished blooming and the flower turns brown, you can prune the spent bloom as well. This not only helps the plant look tidier but also encourages new growth. The best time to prune is in the spring or early summer when it is actively growing. Make sure you only use clean tools and sterilize them after each use to avoid spreading any disease.

When pruning, avoid removing too much foliage at once, as this can stress the plant. After pruning, give the Peace Lily some time to recover. Keep it in a spot with indirect sunlight, and don't water it for a day or two to allow any cuts to heal. Regular pruning helps the plant stay healthy, promotes better air circulation, and enhances its overall appearance.

Propagation

Propagating Peace Lily is best done through division. It means separating a mature plant into smaller sections to create new plants. This process is typically carried out when repotting, usually in the spring or early summer, when the plant is actively growing.

To propagate by division, carefully remove your Peace Lily from its pot. Gently separate the roots to identify natural divisions within the plant. Look for sections where a cluster of leaves and roots naturally form. Use a clean and sharp tool, such as a knife or pruning shears, to cut between the divisions, make sure that each section has enough roots and foliage to thrive on its own. After dividing, replant each section in its own pot with fresh, well-draining potting soil. Water lightly and keep the new plants in a warm spot with indirect sunlight. Avoid fertilizing for a few weeks to give the divisions time to establish themselves. 

Blooming

To encourage blooming, you need to try to adjust the light condition. Peace Lily can tolerate low light, but too much darkness will hinder its growth and reduce blooming. On the other hand, too much bright light can also keep the bracts green and prevent flowers from showing up. Cold weather or extreme heat can also make it difficult for this plant to bloom. Keeping the temperature stable, the soil slightly moist and the humidity around 50% also helps to boost flowering.

Common Problems

One of the most common problems for Peace Lily lovers is the lack of flowering. It can be caused by dry air, high or low temperatures, poor soil, or waterlogged soil. It can also mean that your plant is too young and needs more time to mature before it can bloom. Try to give it consistent care and some diluted fertilizer to boost up the growth rate and blooming. 

Another issue is overwatering, which leads to root rot. This condition happens when the soil stays too wet for too long, causing the roots to suffocate and decay. You'll often see yellowing leaves or drooping stems when this occurs. Underwatering can also be a problem, causing the leaves to turn brown at the tips and edges. The plant may wilt, indicating it's not receiving enough water. Balancing the moisture levels in the soil is crucial to prevent both overwatering and underwatering issues.

Additionally, pests like spider mites, mealybugs, and aphids can attack your Peace Lily, causing damage to the leaves and stems. If you notice sticky residue, webbing, or white cottony patches, you likely have a pest infestation. Regularly inspecting your plant and treating it with insecticidal soap or neem oil can help keep pests at bay.

Moreover, Peace Lilies are sensitive to temperature fluctuations and drafts, which can cause stress and impact their growth. Keep them in a stable environment away from cold drafts or sudden temperature changes.
