How to Set Up an Indoor Water Garden
Water gardens just look elegant. They’re a huge feature and they will definitely catch the eye. They’re also not as difficult to create and maintain as they appear. Once you learn how to set up an indoor water garden, you’re going to be surprised at how easy it is and how many different options you have for creating something amazing.
Creating an Indoor Water Garden
Indoor water gardens of any size only need a few components to function: the container, the water and the plants. You can add additional elements, such as pumps and decorations, but if you have these things, then you can have a water garden. And if you want it to be very simple, this can be one of the simplest DIY projects you’ll ever do.
To create a water garden, choose a container of any size. You can grow a single plant in a glass jar with water if you want to, so size doesn’t really matter. It’s all about the size you have to work with and how much time you’re willing to put in. The container cannot be made of copper, brass or lead. These metals can corrode and get hazardous materials in the water.
Fill the bottom of the container with marbles, pearl chips, pebbles, gravel, whatever you’ve got. Include a piece of activated charcoal to keep the water smelling nice. Add the water and you’re ready.
You can create a water garden in just about any container, from something as small as a glass jar to a big glass bowl to a whole huge indoor water feature that you built yourself.
Types of Plants for an Indoor Water Garden
Sure, you can create a water feature in your home. But that’s just the water part of the water garden. For the garden part, you’re going to need a whole lot of water-loving plants. What can you plant in your water garden, how do you plant it and how do you maintain it?
You might be surprised to find out how many plants can actually be grown without soil. Many popular houseplants and edible plants can be grown in shallow water.

Orchids are incredibly beautiful flowers but they are notoriously difficult to grow. Moth orchid is not so difficult to maintain in a water garden.

About the Water
You don’t want to fill your water garden with tap water. The chemicals in tap water, such as fluoride, can limit or even prohibit plant growth and can foster the growth of algae. You want to use distilled water for your water garden and fountain, if you have a fountain. The water does not need to be changed often, so this will only turn into a big expense if you plan to have a very large water garden.
Water Garden Maintenance
Water gardens need regular maintenance, too. You will have to remove yellow and dead leaves and sometimes, you might need to trim plants if they begin to grow a little too healthy. You also can’t let floating plants cover more than 60 percent of the water’s surface. Otherwise, the roots of the plants in the water garden won’t receive enough light to maintain healthy growth.
Algae can be a problem in water gardens. Use anti-algae pellets or, as a more natural alternative, barley straw. This will prevent algae growth. You can also add a filter or clarifier to the water. A fountain or waterfall, which aerates the water, will also prevent algae growth.
You don’t have to water the plants in your water garden. Just maintain the water level at a certain depth and your plants will grow and thrive. Water naturally evaporates over time and this will happen no matter what you do. Draw a small watermark somewhere that you can see so you can maintain the water at the right level, adding more as needed to get the level right.
Don’t ever clean in or around your water garden tank, stones or any other elements using soap. If you use soap, it can leave a residue which makes it difficult for plants to absorb CO2 and create oxygen.
How to Set Up an Indoor Water Garden
Once it’s all finished, an indoor water garden looks quite high-end and eye-catching. It’s a real feature for any indoor space. But you really don’t need a lot to set up an indoor water garden. You can get fancy with foundation and all sorts of features if you like, but you can just as easily fill up a big glass tank and turn it into a water garden. After all, it’s the plants that add the real beauty to the garden, right? Try different plants, different foundations and play with different ideas to make your water garden what you want. The whole point of a DIY project is to have fun and create something special, after all.
