Amazon Sword Plant
The Amazon Sword Plant (also known as Echinodorus amazonicus) is a large aquatic plant, native to the South American region, especially the Amazon River basin. It grows to an average height of 6-10 inches, in a bushy, thick-stemmed shape with thick, crook-tipped leaves that give it the ‘sword’ shape. The leaves themselves are usually a dark green color, but they may also have brown or yellowish patterns through them or at the edges. When grown in a bright light, the leaves will often become tinged with red. Another thing that makes it distinct is its unique root structure, with sprawling rhizomes and thick, white runners, so it is often used for ground coverage in aquariums.
When it comes to watering, the Amazon Sword Plant prefers a steady, consistent watering routine. The soil should be kept continually moist but not soggy, and should never be allowed to completely dry out. Consistent watering is key to keep the plant healthy and the leaves vibrant. Too much water can lead to root rot and other issues, so be careful not to overwater.
The Amazon Sword Plant needs good lighting to thrive. While they can survive in low light, they'll grow better in brighter lights. Optimal lighting should be soft and indirect, somewhere between medium and high, but avoid intense, direct sunlight. If the leaves of the Amazon Sword Plant become too bright they may quickly bleach or burn.
The Amazon Sword Plant will do fine in temperatures between 65 - 85 degrees Fahrenheit (18-30 degrees Celsius). Water temperature should always stay in the range of 72-78 degrees Fahrenheit (21-25 degrees Celsius). A sudden change in temperature can cause shock and may even lead to death.
This plant prefers a humid environment, the humidity should stay around 80 percent, if not higher. This can be achieved by misting the tank and/or the plant itself each day or by placing a humidifier nearby, making sure not to let the humidity get too high as this can lead to mold and fungi growth.
The Amazon Sword Plant prefers a loose, well-draining aquatic soil. This soil should be loamy, with equal parts of organic matter (peat moss, peat, or coir), clay, and sand/gravel for added drainage. The pH should be between 6.0 and 7.0.
The Amazon Sword Plant should be fertilized regularly, except during the winter. It should be fertilized every month with a slow-release fertilizer that is labeled for aquatic plants. Liquid fertilizer can also be used, but as with any fertilization, consult the label to determine appropriate dosage.
The Amazon Sword Plant is susceptible to common pests and diseases. These include Aphids, Thrips, Mites, Fungal Diseases, and Algae. If not treated in time, they can be fatal for the plant. The best way to get rid of them is by manually removing them with forceps or a cotton swab. To prevent pests, the environment should be kept clean and free of debris. Pesticides can also be used as a last resort, but care must be taken and all necessary safety precautions must be followed.
Depending on the growth rate of the Amazon Sword Plant, it will have to be repotted every 6-12 months. The best time to repot is in late spring or in summer, when the plant is actively growing. When repotting, make sure to use an aquatic potting soil mixed with clay, and redistribute roots evenly and fill the pot. Always be sure to cover the roots with the soil.
It is not necessary to prune the Amazon Sword Plant. If it starts to outgrow its environment, the runner and rhizomes can be trimmed back to the desired length but always be careful when pruning. Trim away any dead or dying leaves and stems to encourage new growth.
Mulching is not necessary for the Amazon Sword Plant, but it can help keep the soil moistened and provide extra nutrition. Organic mulch such as wood chips, compost, leaf litter or grass clippings, can be used around the base of the plant.
The Amazon Sword Plant can be propagated by dividing the plant’s runners and rhizomes. Carefully dig up the sides of the plant and cut the rhizomes and runners, making sure to keep a few of them connected to the mother plant for energy. Repot the newly divided plants in separate pots, and give them all bright, indirect sunlight.
The Amazon Sword Plant does not need extra support but sometimes may lean to one side if given too much light or too little light. If this happens, simply use a stake to hold the plant up and if needed, rotate the plant to the desired position.
The Amazon Sword Plant does not require a rest period. It can be kept in a water environment all year round. However, during the winter months, the temperature should be kept consistent to avoid stressing the plant.
The Amazon Sword Plant is not known to be toxic to pets but it is best to keep them away from the plant, especially if the leaves are eaten.
