Aquatic Banana Plant
Unlike normal banana plants, aquatic banana plants are generally used in aquarium using to clean the water quality and increase the oxygen in the water. They are also known as the Big Floating Heart. These banana plants under water look like their relatives on the ground with their heart shaped leaves and banana shaped roots. The roots are used to store the nutrients for the plant. However, you may spend some time to take care of them because it is not an easy work.
As a member of the Rosette plant family, they can be successfully planted under water due to its special characteristics. They are the hardiest member in this family which can tolerate water environment and low level of light. You should check for any broken leaves beforehand since they cannot self-heal the broken leaves by themselves. So, you should remove any ill or dead parts before putting them in your aquarium. The good thing is that they can reproduce by themselves and you do not need take too much care about this.
When planting them in the water, you can just press the plant on the substrate. You should provide some light for them to make them grow happily. The best temperature for cultivation is between 20 to 30 degrees, and the PH requirement is slightly alkaline (6.0 to 7.0). Some artificial LED lights can be used to provide continuing light for their growth. They should receive at least 12 hours of light each day. In aquarium, you should put your aquatic banana plant in the front to present their roots clearly. You can choose the green or brown colors to suit for your specific environment.
