Can You Grow Peace Lily in Water? Yes, Here's How

By James Wilson · January 24, 2026

Yes, you can grow a peace lily (Spathiphyllum) in water indefinitely with proper care. This method, known as hydroponic cultivation, eliminates soil-related issues like overwatering and pests. Success depends on using a clear or opaque container, providing balanced liquid fertilizer every 4–6 weeks, and ensuring bright, indirect light. Regular water changes and root health monitoring are essential for long-term vitality.

Why Grow Peace Lily in Water?

Hydroponic growth offers several advantages over traditional soil-based methods, especially for indoor gardeners seeking low-maintenance yet visually appealing houseplants.

Benefits of Water Cultivation

Eliminates risk of soil-borne pests like fungus gnats
Reduces chance of overwatering damage
Easier to monitor root health and development
Cleaner display option for modern interiors
Precise nutrient delivery through liquid feeding

Common Challenges

Root rot if water is not changed regularly
Nutrient deficiencies without proper fertilization
Algae growth in transparent containers
Reduced oxygen availability compared to soil

How to Transition a Soil-Grown Peace Lily to Water

Moving your peace lily from soil to water requires careful handling to avoid shock and root damage.

Step-by-Step Process

Gently remove the plant from its pot and shake off excess soil.
Rinse roots thoroughly under lukewarm water to remove all soil particles.
Trim any brown, mushy, or damaged roots with sterilized scissors.
Place the plant in a clean container filled with room-temperature distilled or filtered water.
Ensure only the roots are submerged; keep the crown and leaves dry.
Change the water completely every 7–10 days initially.

Best Containers and Setup for Hydroponic Peace Lilies

The right vessel supports stability, light control, and oxygen exchange.

Container Selection Guide

Material: Glass or food-grade plastic recommended
Size: Slightly larger than root ball with room for growth
Neck Design: Narrow opening helps support the base while allowing airflow
Transparency: Clear jars allow root inspection but may encourage algae; use tinted glass or wrap with decorative sleeve if needed

Nutrient Management for Water-Grown Peace Lilies

Unlike soil, water lacks natural nutrients, so supplementation is critical.

Fertilizing Schedule

Use a balanced liquid houseplant fertilizer (e.g., 20-20-20 NPK)
Dilute to half or quarter strength to prevent salt buildup
Apply every 4–6 weeks during active growing season (spring–summer)
Reduce frequency in fall and winter when growth slows

Parameter	Soil-Based Growth	Hydroponic (Water) Growth	Notes
Average Lifespan	3–5 years	5+ years	With consistent maintenance, water-grown specimens live longer 1
Water Change Frequency	N/A	Every 7–10 days	Prevents stagnation and pathogen buildup 2
Fertilizer Application	Monthly	Every 4–6 weeks	Less frequent due to direct nutrient uptake 3
Root Rot Incidence	High (if overwatered)	Moderate (with poor maintenance)	Better aeration possible in water with proper setup
Flowering Rate	1–2 times/year	1–3 times/year	Improved nutrient access can enhance blooming 4

Table data source:1, 2, 3, 4

Data shows that peace lilies grown hydroponically have the potential for extended lifespan and increased flowering frequency when maintained correctly. While root rot remains a concern, controlled water conditions reduce risks associated with soil saturation. Regular water changes and appropriate fertilization are key differentiators in long-term success.

Light, Temperature, and Humidity Needs

Peace lilies thrive in stable environments regardless of growing medium.

Ideal Conditions

Light: Bright, indirect light (east-facing window ideal)
Temperature: 68–85°F (20–29°C)
Humidity: 50–60%; mist leaves occasionally or use a humidifier
Avoid: Direct sunlight, cold drafts, heating vents

Troubleshooting Common Issues

Even well-maintained water-grown peace lilies may encounter problems.

Symptoms and Solutions

Yellow leaves: Could indicate nutrient imbalance or insufficient light
Brown leaf tips: Often caused by low humidity or chlorine in tap water
Drooping: Check water level and ensure no root congestion
Algae in container: Switch to opaque vase or change water more frequently
No blooms: Ensure adequate light and periodic fertilization

Frequently Asked Questions About Growing Peace Lily in Water

Can peace lilies live in water forever?

Yes, peace lilies can live indefinitely in water if provided with proper nutrients, regular water changes, and suitable light. With optimal hydroponic care, they often outlive their soil-grown counterparts.

Do peace lilies need sunlight in water?

Yes, even when grown in water, peace lilies require bright, indirect sunlight to photosynthesize and bloom. Avoid direct sun, which can scorch leaves and heat the water excessively.

How often should I change the water for a peace lily?

Change the water every 7–10 days to prevent bacterial growth and maintain oxygen levels. Top off between changes if needed, but full replacement is essential for plant health.

Can I use tap water for my peace lily?

Tap water can be used, but it's best to let it sit for 24 hours to allow chlorine to evaporate. Alternatively, use filtered or distilled water to avoid fluoride and mineral buildup, which peace lilies are sensitive to.

Why are my peace lily’s roots turning brown in water?

Brown roots likely indicate early stages of root rot due to stagnant water or lack of oxygen. Trim affected areas, clean the container, and refresh the water immediately. Consider adding an air stone for better aeration in large setups.
