Overview
Eleocharis fluitans (L.) Hook. is a perennial aquatic plant that belongs to the Cyperaceae family. It is commonly known as the "floating spikerush" and is native to North and South America, as well as parts of Europe, Africa, and Asia. This plant is highly adaptable and can grow in a wide variety of aquatic habitats, from slow-moving streams to stagnant ponds and lakes.
Appearance
Eleocharis fluitans has thin, cylindrical stems that can grow up to 50 cm in length. The stems are topped with a cluster of small, brown flower spikes that emerge from the water's surface. The leaves of this plant are reduced to small scales that are arranged in a spiral pattern along the stem. The plant's roots are feathery and can grow up to several centimeters in length.
Uses
Eleocharis fluitans has a variety of uses in the aquatic hobby and industries. It is a popular plant for use in aquariums and aquascapes as it adds a unique texture and visual interest to aquatic environments. It is also used as a biological filter and provides shelter for fish and invertebrates. Additionally, it is sometimes used in wetland restoration projects to improve water quality and prevent erosion.
Light Requirements
Eleocharis fluitans prefers bright light conditions with a minimum of 2 watts per gallon of full spectrum lighting. It can tolerate partial shade but will grow taller and spindly under low light conditions. Providing moderate to high light increases the growth rate and encourages the plant to develop a vibrant green hue.
Temperature Requirements
The plant grows well at a temperature range of 68-85°F (20-30°C). It does best at a slightly cooler temperature, and high temperatures can cause the plant to perform poorly. The plant is not frost tolerant and should be kept indoors in cooler climates or during the winter season.
Soil Requirements
Eleocharis fluitans does not require a nutrient-rich substrate. Fine-grained sand, gravel, or a combination of both is an ideal substrate. In addition, the plant can be anchored to surfaces such as rocks or wood. The substrate should be well-draining since the plant is susceptible to root rot. It is advisable to keep the substrate moist but not waterlogged to promote growth.
Cultivation Methods
Eleocharis fluitans (L.) Hook. can be grown both submerged and partially submerged in a freshwater aquarium. Plant it in nutrient-rich substrate and ensure that it receives ample lighting. A temperature range between 68°F - 82°F and a pH range between 6.0 – 7.5 is ideal for its growth.
Watering Needs
Eleocharis fluitans (L.) Hook. requires high levels of water. Maintain a water hardness of 5-15 dGH, with a water flow between 5-10 cm/s as they prefer moderately flowing water.
Fertilization
You can supplement the growth of Eleocharis fluitans (L.) Hook. by using a fertilizer in the form of a liquid or substrate. Supplementing with iron-rich fertilizers can help promote its growth. Ensure that the nitrate level of the water is less than 15 ppm in concentration.
Pruning
Eleocharis fluitans (L.) Hook. requires pruning to maintain its desired shape and structure. It's a quick grower, so regular pruning will keep it neat and healthy-looking. Trim back any yellowing leaves with a sharp pair of scissors or aquatic plant trimming shears. Pruning should be done once a month.
Propagation Methods for Eleocharis Fluitans (L.) Hook.
Eleocharis Fluitans (L.) Hook. is a plant found in wetlands, marshes, and shallow water bodies. Its propagation can be done through two primary methods. These include:
1. Vegetative propagation
Eleocharis Fluitans can be propagated vegetatively by division. Simply split the clump of Eleocharis Fluitans into individual plants. Each plant should have roots and a sufficient number of stems. These individual plants can now be replanted in the aquarium. Carefully plant each stolon into the substrate, taking care not to bury the leaves, as this can lead to rotting.
2. Seed propagation
Eleocharis Fluitans can also be propagated using seeds. Seed propagation can take longer than vegetative propagation, but it produces more individuals in the long run. Seeds can be obtained from mature flowers or purchased from a reputable dealer. Once you have the seeds, do the following:
- Fill a seed tray with soil or a suitable planting medium
- Sow the seeds on the surface of the soil and cover them with a thin layer of soil
- Maintain moisture by misting the surface regularly
- After a week or two, the seeds will start to germinate. Continue to water them and keep the soil moist
- Once the seedlings have grown big enough, they can be transplanted individually into an aquarium. Carefully plant each seedling into the substrate, taking care not to bury the leaves, as this can lead to rotting.
With proper care, Eleocharis Fluitans can thrive and provide a beautiful and natural look to the aquarium.
Disease and Pest Management for Eleocharis fluitans (L.) Hook.
Eleocharis fluitans, commonly known as the floating spikerush, is a plant species that belongs to the family Cyperaceae. While this plant is generally disease and pest resistant, there are still some common issues that may arise and require attention.
Common diseases
One common disease that may affect Eleocharis fluitans is fungal leaf spot. This is characterized by light brown spots on the leaves that eventually turn dark brown and have a yellow halo around them. To manage this disease, the affected leaves should be removed and destroyed. Additionally, fungicide treatment may help control the spread of the disease.
Common pests
One common pest that may affect Eleocharis fluitans is the armyworm. This pest is a type of caterpillar that feeds on the leaves of the plant, causing damage and potentially killing the plant. To manage this pest, manual removal of the caterpillars and the use of insecticides may be necessary. Another common pest is the whitefly, an insect that feeds on the sap of the plant and may cause the leaves to yellow and die. To manage this pest, the use of insecticides and regular monitoring of the plant is recommended.
It is important to note that prevention is key in avoiding disease and pest problems with Eleocharis fluitans. Ensuring the plant is healthy by providing proper growing conditions, such as adequate light and nutrients, can help prevent issues from arising. Regular monitoring of the plant for signs of disease or pests can also alert the gardener to any issues early on, making them easier to manage.
