Understanding Peace Lilies

Origin and Characteristics

Peace lilies, also known as Spathiphyllum, are popular indoor plants native to tropical regions of America and Southeast Asia. They are renowned for their ability to thrive in shady environments and their beautiful white blooms, which can purify indoor air. Peace lilies typically grow up to 16 inches tall, but larger outdoor varieties can reach up to 6 feet in height.

These attractive houseplants tend to be low-maintenance, prefer indirect sunlight, and require moderate watering. Although peace lilies are usually grown in soil, it is possible to grow them in water as well, allowing the roots to absorb oxygen and nutrients directly from the water.

Common Varieties

Different peace lily varieties can vary in size, appearance, and care requirements. Some common varieties include:

  • SPATHIPHYLLUM WALLISII: A compact peace lily with glossy leaves and elegant white flowers. This variety is often used as a tabletop plant due to its smaller size. Also known as the “Mauna Loa Supreme.”
  • SPATHIPHYLLUM DOMINO: A variegated peace lily with striking white-striped leaves. It is an excellent eye-catching addition to any space.
  • SPATHIPHYLLUM SENSATION: This is the largest of the peace lily varieties, known for reaching heights of 6 feet or more when grown outdoors. It features massive, lush, dark green leaves and beautiful white blooms.

Growing peace lilies in water can be a unique and beautiful alternative to traditional soil cultivation, especially if you are looking for a low-maintenance and aesthetically pleasing option for your home or office. Just make sure to provide the necessary care and conditions for the plants to thrive.

Growing Peace Lily in Water

Preparing Cuttings

To start growing a peace lily in water, first, harvest a fresh peace lily plant. Carefully remove the plant from the soil, making sure not to damage the roots. Gently wash the roots to remove any remaining soil particles. Trim off any dead or damaged roots using sharp scissors. Now, your peace lily is ready to be placed in water.

Water Requirements

Peace lilies grow well in water as long as you provide some nutrients and replace the liquid regularly. Distilled water mixed with hydroponic fertilizer work best for this method. Make sure to change the water every two weeks, scrubbing any algae out of the vessel. Maintaining the pH between 5.8 and 6.5 will ensure the peace lily thrives in water.

Some factors to consider for peace lilies in water:

  • Temperature: These tropical plants grow best at temperatures between 65 and 75 degrees Fahrenheit, so ensure adequate warmth.
  • Sunlight: Water peace lilies don’t require direct sunlight, making them perfect for indoor settings or shaded areas.

Hydroponic Systems

Instead of using soil, peace lilies can be grown in hydroponic systems, which use water as the primary growing medium. There are several types of hydroponic systems to choose from, including:

  • Wick systems: A simple method that uses a wick to deliver water and nutrients to the plant.
  • Nutrient Film Technique (NFT): This technique involves a continuously flowing thin film of water that delivers nutrients directly to the plant roots.
  • Deep Water Culture (DWC): A method in which the plant roots are suspended in nutrient-rich water, allowing for maximum oxygenation and growth.

Growing peace lilies in water can be a creative and visually appealing way to enjoy this popular houseplant. By providing the right water conditions, temperature, light, and nutrients, your water-grown peace lily will thrive and continue to purify the air in your home.

Maintenance and Care

Changing the Water

It is essential to change the water regularly when growing a peace lily in water. Replace the liquid every two weeks to ensure a healthy environment for the plant. Additionally, scrub any algae out of the container during each water change.

Providing Nutrients

Provide your peace lily with hydroponic fertilizer to ensure it receives adequate nutrients. Distilled water is recommended, as it doesn’t contain harmful minerals that might affect the plant’s growth.

Follow these guidelines for proper nutrient provision:

  • Mix in the fertilizer at the appropriate ratio (follow the instructions on the container).
  • Monitor the pH, maintaining it between 5.8 and 6.5.
  • Regularly check the water for any signs of nutrient deficiency.

Lighting Conditions

Peace lilies thrive in adequate light conditions. They typically prefer bright, indirect light to ensure optimal growth. Avoid direct sunlight, as it can scorch the leaves. Placing the plant near a window with filtered light or in a well-lit room would be ideal.

Maintaining Temperature and Humidity

When it comes to temperature, peace lilies prefer a consistent environment as well. Keeping the room temperature between 65°F and 80°F allows the plant to grow healthily.

As for humidity, peace lilies love a moist surrounding. To maintain the ideal humidity levels:

  • Use a humidifier in the room where the plant is located.
  • Placing a tray of water or a small water feature nearby can increase the humidity around the plant.
  • Regularly mist the leaves with distilled water.

Following these steps will help your peace lily grow successfully in water. Remember to be mindful of the water changes, nutrients, lighting conditions, and temperature/humidity maintenance to ensure a healthy and happy plant.

Potential Issues

Growing a peace lily in water can present certain concerns and challenges. In this section, we’ll discuss the potential issues and how to prevent them.

Root Rot

Root rot is a primary concern for peace lilies grown in water. It occurs when the roots of the plant are constantly submerged in water, leading to oxygen deprivation and subsequent decay. To avoid root rot, ensure that the water in which the peace lily is growing is well-oxygenated, which can be achieved by adding an aquarium pump to the container or frequently changing the water.

Pest Infestations

Peace lilies are generally resistant to pests, but growing them in water may attract insects like aphids, spider mites, and mealybugs. To prevent infestations, inspect your peace lily regularly and remove any visible pests. Wipe the leaves with a soft, damp cloth to help keep the pests away, and consider using a natural insect repellent if you notice the presence of insects.

Signs of Stress

Growing a peace lily in water may result in some signs of stress, as the plant is adapting to a soil-less environment. You may observe yellow leaves or wilting, which could be due to a lack of nutrients. One way to combat this issue is by adding a few drops of liquid fertilizer on a bi-weekly basis. Another potential stressor is insufficient light. When growing peace lilies in water, it’s important to provide them with adequate indirect light to encourage healthy growth and prevent leaf damage.

By addressing these potential issues, you can ensure that your peace lily thrives in its water-based environment. Remember, proper care and maintenance will go a long way in helping your plant enjoy a long and healthy life.

Benefits of Aquatic Cultivation

Growing a peace lily in water has several advantages. One primary benefit is that the plant can absorb nutrients directly from the water. In an aquarium setup, the peace lily takes nutrition from the water containing nutrients from fish waste, which helps in cleaning the water and reducing algae growth.

Another advantage of aquatic cultivation is that peace lilies can provide shelter for fish. Their broad leaves and dense root system create a habitat for smaller fish to hide from predators, contributing to a healthier aquarium ecosystem.

Hydroponic peace lily care is relatively low maintenance as you eliminate the need for soil. You only need to ensure that the water level covers the roots and replace the water every two weeks. Additionally, using distilled water and hydroponic fertilizer helps the plant thrive in this setup. Regularly monitoring the pH and keeping it between 5.8 and 6.5 ensures optimal growth as well.

Growing peace lilies in water can be aesthetically pleasing. The luscious green leaves and elegant white spathes create a stunning visual appeal, especially when contrasted against the clear water. This display provides a soothing and calming atmosphere in any living space or office.


Growing a Peace Lily in water is indeed possible, giving you an alternative to traditional soil-based cultivation methods. When choosing to grow a Peace Lily in water, it is essential to use distilled or rainwater since these plants can be sensitive to the minerals found in tap water. Ensuring only the roots are submerged helps keep the plant healthy, as submerging the stems could lead to rotting.

Peace Lilies grown in water typically have a shorter lifespan compared to those cultivated in soil, surviving for about 12-15 months. Thus, it’s a temporary method for showcasing your beautiful houseplant. Temperature plays a crucial role in the plant’s overall well-being, with ideal temperatures ranging between 65-80°F.

In order to grow a Peace Lily in water successfully:

  • Use a fresh plant with healthy roots
  • Place the plant in a suitable container
  • Submerge only the roots in distilled or rainwater
  • Monitor temperature and light conditions

Lastly, remember that Peace Lilies in water still require proper nourishment, as they don’t receive the nutrients they’d usually get from soil. Therefore, it is vital to add a suitable fertilizer to the water periodically, ensuring a well-nourished plant that thrives in its watery environment.

Overall, growing a Peace Lily in water is an exciting and rewarding endeavor when done correctly, allowing you to enjoy this vibrant houseplant in a unique way. Just be mindful of the specific conditions and requirements needed to keep your Peace Lily healthy and flourishing in its water-based life.
