Description

To successfully grow Nymphoides aquatica, also known as the Banana plant aka Banana lily, provide it with moderate to high light, a temperature between 70-82°F, and water parameters in the range of pH 6.0-7.2 and a KH of 5-12. The plant can be planted in a substrate of fine sand or river rock, or left to float, and benefits from regular fertilization with a liquid fertilizer.

Detailed Requirements:

Lighting:

While it can tolerate low light, moderate to high light promotes faster growth and healthier leaves.
Temperature:

A temperature range of 68-82°F (20-27°C) is ideal, with the plant thriving in tropical conditions.
Water Parameters:
pH: Aim for a pH between 6.0 and 7.2.

KH (alkalinity): A KH of 3-6 dKH is recommended for optimal growth.
Substrate:

Fine sand, river rock, or gravel are all suitable options for planting. The plant can also be kept floating, with roots developing into the substrate if desired.
Fertilization:

Nymphoides aquatica benefits greatly from liquid or substrate fertilizer, with liquid fertilizer being particularly effective for feeding from the water column.
Planting:

If planting, ensure the largest root is buried in the substrate no more than one-third of its length to prevent rotting.
CO2:

While not strictly necessary, the plant can benefit from CO2 addition for enhanced growth.
