For the most beautiful Amazon Sword Plants, a loose substrate and an iron-rich fertilizer must be used. The Amazon Sword Plant requires at least 2 watts per gallon of full spectrum lighting (5000-7000K). The aquarium temperature should be from 72°-82°F, with an alkalinity of 3 to 8 dKH and a pH of 6.5-7.5. Propagation is by adventitious plants on the covered peduncles. Best cultivated in large aquariums, Amazon Sword Plants make a great focal point if used singly. When used in groups, they create an interesting background when grown with other aquarium plants.
