Peace lilies (Spathiphyllum) are beloved houseplants known for their graceful white blooms and lush, dark green leaves. These low-maintenance plants not only brighten up indoor spaces but also help purify the air. For plant lovers looking to propagate peace lilies and grow them sustainably, using plastic bottles is an excellent option. This simple, eco-friendly method makes plant care accessible, affordable, and environmentally conscious.

Growing peace lilies in upcycled plastic bottles allows you to reduce waste while enjoying the satisfaction of nurturing a beautiful plant from root to leaf. Whether you’re new to propagation or an experienced gardener, this project is easy and rewarding.

Why Choose Plastic Bottles for Peace Lily Propagation?

Plastic bottles are a convenient, readily available alternative to traditional pots. They offer several advantages when it comes to rooting and growing peace lilies:

  • Recyclable and cost-effective – No need to buy new containers.

  • Compact size – Ideal for windowsills, desktops, and small spaces.

  • Root visibility – Transparent bottles let you monitor root growth and water levels.

  • Customizable design – Bottles can be cut, shaped, or decorated to suit your style.

Plus, this method supports sustainable gardening by reusing materials that would otherwise be discarded.

Supplies You’ll Need

To root and grow a peace lily in a plastic bottle, prepare the following:

  • A healthy peace lily plant (or a division)

  • A clean, empty plastic bottle (1.5-2 liters is ideal)

  • Sharp scissors or a utility knife

  • Pebbles or small stones (optional, for drainage)

  • High-quality potting mix or clean water (depending on the method)

  • Activated charcoal (optional, prevents odor in water)

  • Spray bottle for misting

  • Optional: decorative materials like twine, paint, or fabric

Preparing the Plastic Bottle

1. Cut the Bottle
Using scissors or a craft knife, carefully cut the bottle about one-third from the top. The bottom part will be used as the planter. If you’re setting up a self-watering system, invert the top section into the bottom like a funnel and thread a cotton wick through the cap.

2. Create Drainage (for soil method)
If growing in soil, poke small holes at the bottom for drainage. Add a layer of pebbles or stones to prevent the roots from sitting in excess moisture. If growing in water, skip this step.

3. Clean and Dry
Make sure the bottle is thoroughly cleaned and dried before use to avoid bacterial growth.

Rooting Peace Lily Cuttings

Peace lilies are typically propagated through division, not from leaf or stem cuttings.

Steps for dividing and rooting:

  1. Remove the parent plant from its pot and gently shake off excess soil.

  2. Locate a section of the plant with its own roots and a few healthy leaves.

  3. Separate the section using clean hands or a knife, ensuring roots remain intact.

  4. Rinse the roots gently under water to prepare for propagation.

Now you’re ready to grow your peace lily in either water or soil.

Growing in Water (Hydroponic Method)

1. Fill the bottle with clean, filtered or distilled water. Avoid tap water with chlorine or fluoride, which can harm the plant.

2. Add activated charcoal (optional) to keep the water fresh and prevent bacterial buildup.

3. Place the peace lily division so that only the roots are submerged in water. Keep the crown and leaves above the waterline to avoid rot.

4. Change the water weekly and rinse the roots. You can add a drop of liquid houseplant fertilizer once a month during active growing seasons.

This method allows for easy monitoring of root development and creates a modern, minimalist look.

Growing in Soil

1. Fill the bottom of the plastic bottle with your drainage material (pebbles or stones), then add a layer of high-quality, well-draining potting soil.

2. Place the peace lily division in the center and fill around the roots with soil, pressing gently to eliminate air pockets. Keep the base of the plant (crown) slightly above the soil line.

3. Water thoroughly until excess drains out. Ensure the soil remains moist but not soggy.

4. Place the plant in bright, indirect light, avoiding direct sun which can scorch the leaves.

Care Tips for a Healthy Plant

  • Light: Peace lilies prefer bright, indirect sunlight but tolerate low-light conditions. Avoid placing them in direct sun.

  • Watering: Keep the soil evenly moist. If growing in water, change it weekly.

  • Humidity: Mist the plant occasionally, especially in dry environments.

  • Cleaning: Wipe the leaves with a damp cloth to remove dust.

  • Fertilizing: Use a balanced houseplant fertilizer monthly during spring and summer.

Styling Your Bottle Planter

Plastic bottle planters can be both practical and decorative. Wrap the outside with twine, paint it with acrylics, or place it inside a woven basket or decorative container. You can also hang the bottle planter or line several on a shelf for a cohesive display.

Conclusion

Rooting and growing a peace lily in a plastic bottle is a simple, sustainable, and beautiful way to enjoy houseplants. By reusing materials and practicing thoughtful care, you can create a healthy, eye-catching indoor plant setup with minimal cost and maximum satisfaction. With just a bottle, a division, and a little love, your peace lily can flourish—bringing green elegance and cleaner air into your home.
