Rotala wallichii

Description

Rotala wallichii is an elegant stem plant originating from soft, slightly acidic waters in South-Eastern Asia. Its inflorescence has bright purple flowers. Even though it is not quite easy in cultivation it is a highly popular plant.

R. wallichii needs lots of light, CO2 fertilisation and a well-balanced supply of nutrients to grow well. The light intensity should at least be 0.5 watts per litre in order for it to attain intensive colours and to support growth. A good supply of CO2, either with bio CO2 or a system using pressure bottles is indispensable. Rotala wallichii grows best if the nitrate level never falls to zero but does not exceed 10 to 15 mg per litre either. A high phosphate content of 1-2 mg per litre is preferred, as well as a good supply of iron and micronutrients.
