Amazon Sword plants are attractive common freshwater aquarium plants. Like many other fresh plants, they can help liven up an aquarium. Before planting them however, you need to make sure you provide the right growth conditions, and properly take care of the plant after planting.

Make sure the water’s pH is between 6.5 and 7.5. Most tap or well water will usually fall within this pH range, but you should still test it before adding Amazon Sword plants to your aquarium. You can buy pH testing kits specifically for aquariums from your local pet store (though they can also be purchased online).
- Controlling an aquarium’s pH level is done through the use of alkaline buffers, which increase water’s pH level, and acid buffers which lower it.
- To reach and maintain a pH level in the 6.5 to 7.5 range, you’ll likely need to use a combination of these products. Always follow the product’s instructions to safely control your aquarium’s pH level.

Regulate the aquarium’s temperature. For optimal growth, the water’s temperature should stay between 72 and 82 degrees Fahrenheit (22 to 28 Celsius). Use a thermometer to check the tank’s temperature regularly and adjust accordingly.
- If the water is too cold, install an aquarium heater. The wattage you need will depend on your aquarium’s size, with 100 watts being suited for 20 gallon tanks, 175 watts for 55 gallon tanks and 300 watts for 100 gallon tanks.
- To cool an aquarium in hotter seasons, you can replace the glass top with a screen, and position a fan so it blows across the water. If the water is too warm for an extended period, you should consider getting a chiller, which will help cool the water.^{[1]

While Amazon Swords can tolerate various light intensities, you’ll want to keep them in low to medium lighting conditions. Too much light might cause leaf burn, making your plant more likely to start wilting. Make sure to keep the lights on for a good chunk of the day to promote growth.^{[2]

Provide nutrient-rich soil for your plant. Amazon Sword plants need nutrient-rich soil, especially rich in iron, in order to thrive. If you need to add soil (also called substrate) to your aquarium tank without removing everything, you can use a PVC pipe, two inches in diameter (5 cm) to deliver the substrate. Gently push the pipe into your existing soil to create a seal, then pour your substrate through. Lift the PVC pipe slightly to spread it around the bottom of the tank.
- When you plant your sword plant, add a root tab for some extra nutrients. Alternatively, you can use a liquid plant food appropriate for aquariums.^{[3]

- If needed, you can also transfer your fish and uproot any plants in your tank to change your soil. You shouldn’t need to remove the water from the tank to do this.^{[4]

Scoop out a small hole, wide enough to cover the Amazon Sword’s root bundle. The hole should be high enough that the plant’s crown (where the roots meet the stem) is just at the soil line. Set the plant in the hole and scoop the dirt back onto the roots. It’s important that you pack the dirt tightly around the roots to prevent the plant from floating up. Make sure not to cover the plant’s crown, as you bury the roots.^{[5]

Amazon Swords can grow quite large, so you want to avoid placing them near the middle or the front of your aquarium. Not only will they obscure your view of the tank, but they can overtake other plants and even block out the tank’s lights.^{[6]

Taking Care of Your Amazon Swords

Amazon Sword plants can grow to be up to 20 inches in height, and will grow long running stalks that spread into new plants. If you don’t have a particularly large tank, it’s even more important to prune the plant effectively. Prune it away from the light sources, which it tends to snuff out, and keep it from spreading too wildly around the tank. It’s best to use shears for this.^{[7]

Wilting Amazon Sword leaves won’t heal or regain their green sheen. Once you notice leaves that have turned transparent, brown or are wilting, you should pluck them from the main plant. You can use shears to trim them off, but you can also just pull them off with your hands. Grab the leaf as close to the stem as possible, and pull upwards. Dead leaves should come off without using too much pressure.^{[8]

Aquariums are complex ecosystems, and any number of factors might cause algae to start growing on your Amazon Swords. If this starts to happen, use a microfiber cloth to wipe off the algae regularly. If the situation doesn’t resolve itself after a few days, it might be caused by a nutrient imbalance in the tank, overfeeding or improperly maintained filters.

Question

Do you have to remove the plastic bucket the plants arrive in?

Chris

Top Answerer

Yes, you will have to remove the plant from the plastic bucket before planting it. The bucket will restrict the area the roots can grow in, causing the plant to become root bound and possibly stunting the plant's growth.

Amazon sword plants require a nutrient-rich soil in order to grow well. You should look for soils that are rich in iron, as this is one of the most essential nutrients for these plants to grow well.

Question

Can I plant one in gravel?

Chris

Top Answerer

While it's possible, Amazon sword plants require many nutrients that they can get from potting soil. When planting in gravel, you would have to provide many of the nutrients manually, which can turn into somewhat of a hassle.
