If you love keeping aquariums, you know that Water Wisteria is a great addition to any tank. With its long, delicate leaves, it creates a lush, green backdrop for other plants. Unfortunately, it’s not always easy to keep Water Wisteria alive and happy. If your Water Wisteria is looking sad and wilted, it may be dying. Here is a guide to diagnosing and reversing the death of your Water Wisteria.

Check for Root Rot

The first thing you should check for when diagnosing a dying Water Wisteria is root rot. This is a common issue that can be caused by too much water in the tank. If you have recently changed the water in your tank, the root system of your Water Wisteria may not have had enough time to adjust. When the roots sit in too much water for too long, they can rot. To check for root rot, pull the Water Wisteria out of the tank and inspect the roots. If they are brown and mushy, then you have root rot. The best way to fix this is to trim off the dead roots and replant the Water Wisteria in fresh substrate.

Check for Algae

Another common cause of Water Wisteria death is algae. Algae can quickly overtake an aquarium, and it can smother and kill plants like Water Wisteria. To check for algae, look carefully at the leaves and stems of the plant. If the leaves are coated in green, brown, or black fuzz, then you likely have an algae problem. To remove the algae, you will need to clean the tank thoroughly. This includes scrubbing the sides, vacuuming the substrate, and doing a water change. Make sure to also check for other sources of algae, such as decorations and plants.

Check for Nutrient Deficiency

If your Water Wisteria is not showing signs of root rot or algae, then it may be suffering from a lack of nutrients. This is a common problem for aquarium plants because the substrate in the tank may not contain enough of the nutrients that the plants need. To test for nutrient deficiency, take a sample of the substrate and send it to a lab for testing. You can also purchase an at-home test kit to get a general idea of the nutrient levels in your tank. If the nutrient levels are low, you may need to add a fertilizer to the tank.

Check the Lighting

Low lighting can also cause your Water Wisteria to die. This is because plants need light to produce energy and grow. If your tank is getting too little light, the Water Wisteria will start to die back. To check the lighting, measure the intensity of the light with a light meter. You should also make sure that the light is the right spectrum for aquatic plants. If the light is too weak or the wrong spectrum, you will need to replace it with a stronger, more suitable light.

Check for Pests

Another common cause of Water Wisteria death is pests. Aquarium pests such as snails, shrimp, and fish can all eat away at Water Wisteria. To check for pests, inspect the leaves of the plant for signs of damage. You should also inspect the substrate and decorations for any pests. If you find any, you will need to remove them before they damage the Water Wisteria further.

Check the pH Level

Finally, you should also check the pH level of your tank. Water Wisteria prefers a pH level of 6.5-7.5. If the pH level is too high or too low, it can cause the plant to die. To check the pH level, you will need to purchase a test kit and take a sample of the water. If the pH level is off, you can adjust it by adding a pH buffer to the tank.


Water Wisteria can be a beautiful addition to any aquarium, but it can also be a tricky plant to keep alive. Before you give up hope, take the time to diagnose your dying Water Wisteria. Check for root rot, algae, nutrient deficiency, pests, and the pH level. If you can identify the problem and take steps to fix it, you may be able to save your Water Wisteria from certain death.
