What Is An Indoor Water Garden?
Indoor water gardens are a beautiful and innovative way to grow plants without soil, using water as the primary growing medium. These gardens create a peaceful, natural aesthetic while offering numerous benefits, such as improved air quality, minimal maintenance, and a unique decorative touch.
Be it on a windowsill, a tabletop, or in a cozy corner of your home, an indoor water garden brings a sense of calm and greenery to your space.

Types of Indoor Water Gardens
Whether you prefer a minimalist glass vase with floating greens or a lush, submerged ecosystem, an indoor water garden is a versatile and rewarding addition to any home.
They can take various forms depending on the plants used and their water requirements.
Each type of indoor water garden offers its own charm and benefits, allowing you to create a setup that suits your style and available space.
Here are three main types:
1. Fully Aquatic Water Gardens
Fully aquatic water gardens feature plants that are entirely submerged in water with common plants including Anacharis, Java fern, and Amazon sword.
These gardens are often paired with decorative elements like pebbles, driftwood, or even small fish.

2. Semi-Aquatic Water Gardens
Semi-aquatic gardens contain plants that have their roots submerged in water, while their leaves and stems grow above the surface such as Pothos, Lucky bamboo, and Spider plants.
These gardens are typically arranged in glass vases, jars, or aquariums.

3. Floating Plant Water Gardens
These gardens use floating plants that thrive on the water’s surface without needing to be anchored in a substrate. Some of the popular floating plants include Duckweed, Water lettuce, and Water hyacinth.
These gardens are ideal for decorative water bowls or aquariums.

Choosing the Right Plants for Your Indoor Water Garden
Selecting the right plants is crucial for creating a thriving indoor water garden. The choice of plants depends on their adaptability to water environments.
Here’s a quick guide to help you make the best choices.
True Aquatic Plants
These plants are fully submerged in water and thrive in aquatic environments.
- Java Moss: Hardy and versatile, great for adding texture.
- Amazon Sword: Large, broad leaves, perfect for bigger containers.
- Anubias: Low-maintenance and ideal for beginners.
Semi-Aquatic Plants
Roots are submerged in water, but stems and leaves grow above the surface.
- Philodendron: Tropical and glossy, perfect for an indoor garden.
- Pothos: Trailing vines that grow well in water.
- Spider Plants: Easy to grow with air-purifying properties.
Floating Plants
These plants float on the water’s surface, with roots dangling below.
- Duckweed: Covers the surface and prevents algae growth.
- Water Lettuce: Adds a decorative touch while improving water quality.
- Water Hyacinths: Beautiful flowers and excellent for filtering water.
Considerations for Plant Selection
- Light: Some plants need low light (Java moss), while others need more (Amazon sword).
- Growth Rate: Fast-growing plants may need more space to avoid overcrowding.
- Compatibility: Choose plants with similar light and water needs for balance.
Selecting the Appropriate Container for Your Indoor Water Garden
The container you choose plays a significant role in the success of your indoor water garden.
Here are some factors to consider:
Types of Containers
- Glass Bowls: A simple and elegant choice, glass bowls allow you to showcase your plants while offering a clear view of the roots and water.
- Vases: Vases come in various shapes and sizes, making them perfect for small, decorative water gardens. Choose a vase with a wide opening to allow plants to spread and grow comfortably.
- Aquariums: For larger setups, aquariums provide ample space for a more diverse range of plants and even small fish. They also help maintain water stability and quality.
- Jars: Jars are ideal for smaller, low-maintenance setups. They are easy to clean and can be used to create a minimalist or modern look.

Size Considerations and Transparency
The size of your container should be based on the number and size of plants you plan to include. Larger plants, like the Amazon sword, require a bigger container with more room for root development. Smaller plants, like Duckweed or Java moss, can thrive in smaller containers.
A clear container allows you to see the roots and water levels, adding to the visual appeal of your water garden. Transparency also helps with monitoring plant health and water clarity, making it easier to maintain a healthy ecosystem.
How to Create and Maintain Your Indoor Water Garden: Step-by-Step Approach
Building an indoor water garden is a simple yet rewarding project.
By following these simple steps, you can create a beautiful, low-maintenance indoor water garden that brings tranquillity and nature into your home.
Here is the step-by-step procedure:
1. Gather Your Materials
- Container: Choose a glass bowl, vase, aquarium, or jar, depending on your space and plant selection.
- Substrate: Pick from aquarium gravel, river rocks, or Fluval Stratum to support plant roots.
- Plants: Select the plants you want based on your container size and water requirements (true aquatic, semi-aquatic, or floating).
- Decorative Elements: Consider adding stones, driftwood, or ornamental figures for visual appeal.
2. Clean Your Container
Thoroughly clean your container with warm water and mild soap (avoid chemicals), then rinse it well to ensure it’s free of any residue.
3. Add Substrate
Place your chosen substrate in the bottom of the container. If using gravel, spread it evenly. A thin layer is fine for smaller plants, while larger plants may need a thicker layer.
Make sure the substrate provides stability and supports plant roots.
4. Position and Anchor Your Plants
- Submerged Plants: Fully submerge roots in water and ensure the plant is anchored properly.
- Semi-Aquatic Plants: Place roots in the water while allowing the leaves to grow above the surface.
- Floating Plants: Gently place them on the water’s surface.
Use small rocks or pebbles to anchor larger plants and keep them stable.

5. Fill with Water
- Use Filtered Water: It’s best to use filtered or purified water to avoid chemicals that could harm plants.
- Tap Water: If using tap water, let it sit for 24 hours to allow chlorine to dissipate before filling your container.
6. Add Decorative Elements
Place stones, driftwood, or figurines to enhance the visual appeal of your water garden. Be careful not to overcrowd the space, and make sure the elements don’t obstruct plant growth.
7. Place Your Water Garden
Put your indoor water garden in a location that receives the appropriate amount of light for the plants you’ve chosen. Ensure it’s not in direct sunlight, as this could cause algae growth or overheating.
8. Maintain Your Water Garden
- Water Level: Check the water level regularly and top it off as needed.
- Water Quality: Keep an eye on the water quality and change it every 2–4 weeks if necessary to prevent stagnation.
- Plant Care: Trim dead leaves, and monitor plant growth to ensure a healthy, thriving water garden.
9. Incorporating Aquatic Life (Optional)
Adding aquatic life, such as small fish or snails, can enhance the beauty and balance of your indoor water garden.
Fish help create a more natural ecosystem by feeding on algae, while snails can help clean up debris. However, be mindful of the space and plant selection, as some aquatic life may require more room or specific water conditions.
If you choose to add fish, ensure your water garden is large enough to support them and that the plants are hardy enough to thrive alongside the aquatic creatures.
Lighting for Your Indoor Water Garden
Proper lighting is key to the health of your indoor water garden. Plants need light for photosynthesis, and without enough, they may not thrive.

Lighting Options
With the right lighting, your indoor water garden will surely flourish!
1. Natural Light:
- Best for: Gardens near windows with indirect light.
- How much: 6–8 hours of indirect light per day. Avoid direct sunlight to prevent algae and overheating.
2. LED Grow Lights
- Best for: Low-light areas or rooms without natural sunlight.
- How much: Choose LED grow lights for balanced light. Use for 12–16 hours a day.
Tips
- Watch for stress: Yellowing leaves or slow growth can indicate insufficient light.
- Timers: Use a timer for consistent light cycles.
- Reflective Surfaces: Place your garden on a white surface to maximize light.
Common Challenges and Solutions for Indoor Water Gardens
Indoor water gardens can face a few common challenges such as algae growth, pests and dirty water.
Here are some perfect solutions for such challenges:
