How to grow water lily on rooftop / Planting water lilies in pots at home

Growing water lilies on your rooftop or in pots at home can transform your space into a serene, aquatic haven. These beautiful flowers not only add aesthetic appeal but also promote a calming atmosphere. Here’s a step-by-step guide to help you successfully grow water lilies in pots on your rooftop.

Materials Needed

  • Water lily tubers (rhizomes)
  • Large pots or containers (at least 12-18 inches deep and wide)
  • Heavy garden soil or aquatic plant soil
  • Gravel or pebbles
  • Fertilizer tablets (specifically for aquatic plants)
  • Water
  • Plastic mesh or fabric

Step-by-Step Instructions

1. Choose the Right Container

Why It Matters: The size and type of container affect the growth and health of water lilies.

Tip: Select large, wide pots at least 12-18 inches deep to allow ample space for the roots and the spread of the lily pads. Ensure the pots have no drainage holes to retain water.

2. Prepare the Soil

Why It Matters: Proper soil ensures good root development and nutrient supply.

Tip: Use heavy garden soil or specially formulated aquatic plant soil. Avoid using light, sandy, or potting soil, as these can float and cloud the water.

3. Plant the Water Lily Tubers

Why It Matters: Correct planting depth and positioning promote healthy growth.


  • Fill the pot with soil up to 3-4 inches from the top.
  • Create a small mound of soil in the center.
  • Place the water lily tuber at an angle with the growing tip facing upward and the roots spread out.
  • Cover the tuber with soil, leaving the growing tip exposed.
  • Add a layer of gravel or pebbles on top to prevent the soil from floating.

4. Add Fertilizer

Why It Matters: Fertilizer provides essential nutrients for robust growth and blooming.

Tip: Push a couple of aquatic plant fertilizer tablets into the soil around the tuber. Follow the product instructions for the correct dosage.

5. Fill the Container with Water

Why It Matters: Water lilies need a stable aquatic environment.

Tip: Slowly fill the pot with water, ensuring not to disturb the soil. Use dechlorinated water or let tap water sit for 24 hours to allow chlorine to evaporate.

6. Position the Pots on Your Rooftop

Why It Matters: Adequate sunlight is crucial for water lilies to thrive.

Tip: Place the pots in a location that receives at least 6-8 hours of direct sunlight daily. If possible, provide partial shade during the hottest part of the day to prevent overheating.

7. Maintain Water Levels

Why It Matters: Consistent water levels ensure the health of the water lilies.

Tip: Regularly check the water level and top up as needed to keep the soil submerged. Water lilies prefer still water, so avoid placing them in areas with strong winds.

8. Monitor and Care for Your Water Lilies

Why It Matters: Ongoing care promotes healthy plants and beautiful blooms.


  • Remove any yellow or dead leaves to keep the plants healthy.
  • Fertilize every 4-6 weeks during the growing season.
  • Watch for pests like aphids and treat with appropriate methods if necessary.


Growing water lilies on your rooftop or in pots at home is a rewarding and beautiful way to enjoy these stunning plants. By following these steps and providing the right care, you can create a tranquil water garden that enhances your living space. Enjoy the serene beauty and the delightful blooms of your water lilies right at home.
