Amazon sword plants are one of the most popular freshwater aquarium plants because they are easy to grow and take care of. These plants are well-loved by aquarium fish because they provide excellent shelters and places for them to lay eggs. You can use a variety of substrates in which to grow your Amazon sword plant. Amazon swords can adapt and even thrive in most water environments, as long as they get the right amount of light exposure.
Plant your Amazon sword in small-grained substrate, such as fine pebbles and clay, in a large, water-filled aquarium. You can mix vermiculite into your substrate to help with growth.
Give your Amazon sword 12 hours per day of good light. Consider putting a timer on your aquarium lights to ensure enough light exposure.
Fertilize your Amazon sword plant with laterite, which you can find at most aquarium shops or specialty plant stores. Try a leaf fertilizer and a root fertilizer with iron as well, but be sure to read the directions on the package and avoid over-fertilizing the plant.
Maintain a water pH level between 6.5 and 7.5. These freshwater plants are quite adaptable, so you don’t have to fuss too much over the exact pH levels. Keeping the levels within or around this range is optimal, however.
Snip and remove any yellow or torn leaves, especially when you first get your Amazon sword plant. Also, cut off any roots that aren’t white and snip off the tips of the healthy roots to enhance new growth.
