Knowing how often to water houseplants can be difficult. Cultivating them in a container filled with liquid means you don’t have to worry about this.

What Type of Container can I Use?

You can use any bottle, jar, vase or glass to hold your flowers as long as it is watertight.

Try to select a container which is an appropriate size to hold the plant. Freshly cut stems are fine for small bottles, but as they develop you will need to move them into a larger container.

Test tubes are a trendy way to display single cut stems. The narrow tubes, such as these by DEPEPE are also a great way to propagate cuttings. Additionally cultivating in clear containers means you can watch the roots develop.

Vases come in a range of shapes, sizes and materials. Single stems are best in narrow neck vases.

Wall vases or wall mounted containers also come in a range of shapes and sizes. These are ideal for plants that grow in water because many of these specimens don’t need direct sunlight meaning they don’t have to be on or near a windowsill.

Old Glasses, chipped and old glasses need not be discarded. Instead repurpose them for your liquid loving specimens. Similarly any empty jars which are just sitting at the back of a cupboard doing nothing can also be used to display houseplants or root cuttings.

Test tubes provide an interesting way to display single stem flowers. 

When selecting your container, try to avoid any made of copper, brass or lead. Metals can corrode when in contact with fertilizer. This, in turn, can damage your flowers.

Darker or opaque containers may make it harder to see the roots but they do deter algae from forming.

Additional Tips

This gives the chlorine time to dissipate. Place your container in bright, indirect light and away from heat sources like stoves and radiators.
