How to Grow Houseplants in Water Bottles

Growing plants in water, whether houseplants or an indoor herb garden, is a terrific hobby for the rookie gardener (excellent for kids! ), persons with limited space, those who are afraid of getting their hands dirty, and those who struggle to keep their plants watered.

This type of plant cultivation is not only easy on the gardener’s time and energy but also very resilient to common plant pests and illnesses.

Growing Plants in Water

Water is a common medium for plant propagation since many plants thrive in it.

There are many who prefer to utilise bottles or other containers to start the germination process of houseplants.

Many homes include at least one water garden, which can range in size from a few houseplant cuttings floating in a bowl to a few full-grown plants perched on the kitchen window ledge.

Plants may be grown in just about any container as long as they can hold water, and thus provides greater design freedom than soil-based methods.

Though it takes longer to see results when growing houseplants in water as opposed to soil, an indoor water garden will look beautiful for years to come.

How to Grow Plants in Water

It is possible to use any container that can store water to cultivate an indoor water garden.

Growing plants in bottles are one possibility, but really any watertight container can do, as long as it’s not made of copper, brass, or lead.

There is a risk that metals will corrode in the presence of fertiliser, damaging the plants.

Algae can also be avoided by storing your food in a dark or opaque container.

You can use florist’s foam (the best option), crushed Styrofoam, gravel, pearl chips, pebbles, sand, marbles, beads, or any other item that inspires your imagination to fill the container until it is three-quarters full.

Add a pinch of a powdered or small piece of charcoal to keep the water pure and clean smelling.

Finally, mix together a diluted concoction of water and fertiliser, using a water-soluble fertiliser in the amount of one-quarter of the manufacturer’s suggestion. The time has come to select your desired plant.

Good Plants for Water

Hydroponic farming can also refer to the practice of growing houseplants without soil, however commercial growers utilise a more precise mixture of water for liquid nourishment.

We have made a diluted fertiliser and confirmed that it, along with water, will promote the plant’s growth.

With an understanding of the fundamentals of hydroponics in hand, it is time to select suitable plants.

A few examples of suitable plant “seeds” for water include:

Some of the easiest plants to root from cuttings in water are vining or creeping plants, but rooted species can also be employed.

Remove any rotten or dead leaves or branches and wash the soil thoroughly from the roots of the “soon-to-be indoor water garden plant.”

The plant should be submerged in a mixture of water and fertilizer.

Dissipation means you may occasionally need to replenish the solution.

Every four to six weeks, completely change up the nutrient solution in the indoor water garden.

Use a dark or opaque container to slow algae growth, as indicated above.

Nonetheless, if algae growth becomes a problem, the treatment must be changed more frequently.

Caring for indoor plants that grow in water

Growing plants in water are wonderful since it requires less attention.

When the water level gets low, I replenish it with fresh water, and I replace the water entirely once every week or whenever it starts to get hazy.

Add a few drops of a liquid organic houseplant fertilizer to the water once in a while to give your plants a boost.

Your plants may begin to develop roots after a few weeks or months.

You can take them out of the water and put them in a pot if you want to multiply them.

Most of the plants I keep in water for the long term thrive with minimal care for years when given a location with indirect sunlight.

Maintenance and Problems

If you’ve followed the instructions above carefully, you should have a healthy cutting that is actively growing new roots. Hurrah!

Growing houseplants in water has the benefit of requiring less upkeep, though there are still a few things to remember.

Water changes.

Nutritional elements in the water can be taken up by the plant.

Decomposing plant matter, such as leaves or roots, could taint the water.

All of this points to the need of maintaining a consistent schedule of water changes.

If the roots of your cutting are just starting to form, you should wait to apply fertiliser.

However, as time goes on, you can incorporate a few drops of liquid houseplant fertiliser with each subsequent watering.

Water from a pond or aquarium would be ideal. The nutrients in fish poop will do wonders for your plant.


Colonies of algae appearing? You could be giving your plant too much sunshine or too much fertiliser.

Algae growth is not always harmful, but it is ugly and difficult to clean up if the plant is confined to its container.

Most algae can be eliminated by simply covering the glass for a week or two, cutting off the algae’s source of light.
