Whether you are interested in its medicinal properties or its beauty as an ornamental plant, this unique species is definitely worth exploring.Light Requirements
Eriocaulon aquaticum (Hill) Druce prefers bright to medium light conditions but can also survive in shaded areas with minimum lighting. The plant species does well under direct sunlight only when the water condition is stable. However, the light intensity and duration largely depend on the depth of the water bodies in which the plant grows.
Temperature Requirements
The plant species can tolerate wide temperature ranges and thrive well in tropical to subtropical areas. Its growth condition ranges between 20 – 30 degrees Celsius but can still survive in temperatures between 10 – 36 degrees Celsius. It is advisable to keep this plant species at a constant temperature to prevent stress.
Soil Requirements
E. aquaticum is a versatile plant that can grow in a wide range of soil conditions. It prefers a sandy or muddy substrate that is nutrient-rich but doesn’t contain too many nutrients that can trigger harmful algal blooms and promote the growth of weed species. A substrate with a pH range between 5.0 – 7.5 is optimal for the species.
Cultivation Methods
Eriocaulon aquaticum is an aquatic plant that thrives in both freshwater and brackish water. It is relatively easy to cultivate and perfect for beginner aquarists. To cultivate this plant, start by planting it in a substrate that is rich in nutrients. Ensure that the substrate is covered in a layer of sand to prevent nutrient leaching. You can also anchor the plant to rocks or driftwood using a light thread or fishing line.Watering Needs
Eriocaulon aquaticum requires a consistent water supply to thrive. Ensure that the aquarium or pond in which the plant is growing has a stable water supply. You can achieve this by installing a filtration system to keep the water clean and in optimal condition. The water should be changed regularly to avoid the buildup of harmful toxins that may harm the plant. It is recommended to change 10-15% of the water every week to keep the water clean and nutrient-rich.Fertilization
Eriocaulon aquaticum requires regular fertilization to maintain optimal health. You can use root tabs or liquid fertilizers to provide essential nutrients that are lacking in the substrate. When using root tabs, ensure that they are placed near the base of the plant for easy absorption. When using liquid fertilizers, ensure that they are applied according to the manufacturer's instructions. Overfertilization may lead to the buildup of harmful toxins that can harm the plant.Pruning
Pruning is an essential part of eriocaulon aquaticum's cultivation and care. Regular pruning ensures that the plant remains in optimal health and shape. When pruning, use a sharp and clean pair of scissors to avoid damaging the plant. Remove any yellow or dead leaves to prevent the spread of disease. You can also trim the plant to maintain the desired shape and size. It is recommended to prune the plant every three months or as necessary.Propagation Methods for Eriocaulon aquaticum (Hill) Druce
Eriocaulon aquaticum (Hill) Druce, commonly known as seven angle pipewort or swamp candles, is an aquatic plant that belongs to the family Eriocaulaceae. Propagation of this plant can be done through several methods, which include:
Seed Propagation
Propagation of Eriocaulon aquaticum can be done through seeds collected from mature plants. The seed should be planted immediately in a seedbed that is covered with shallow water. Germination usually occurs within 3-4 weeks.
Vegetative Propagation
Eriocaulon aquaticum can be propagated vegetatively through division or cuttings. Division involves separating the plant into smaller sections and replanting them. Cuttings can be taken from the stem and planted in a pot or directly into the water.
Runners Propagation
Propagation through runners is also possible with Eriocaulon aquaticum. Runners are the horizontal stems that grow along the surface of the water. These stems will form adventitious roots where they come into contact with the substrate. These roots can be severed and the new plant can be relocated to a new location.
Aquatic Propagation
Eriocaulon aquaticum can be propagated through tissue culture. This process involves taking small plant tissue samples and growing them in a sterile environment. This process can produce a large number of plants in a relatively short period.
Disease management
Eriocaulon aquaticum rarely suffers from diseases, but when it does, the most common disease is fungal leaf spot. The symptoms of fungal leaf spot include circular, brown or black spots on leaves that may merge and cause leaf yellowing and drop. To manage fungal leaf spot, remove and dispose of the infected leaves. Ensure that the plant is not overwatered and receives adequate sunlight and air circulation. Apply fungicides as necessary, following the manufacturer's directions.
Another disease that may affect Eriocaulon aquaticum is root rot, which is caused by overwatering and poorly-drained soils. The symptoms of root rot are wilting, yellowing, and dropping of leaves, accompanied by a foul odor. To manage root rot, reduce watering frequency and ensure that the plant is growing in well-draining soil. Remove and dispose of infected plant parts and treat the remaining plant with a fungicide.
Pest Management
Eriocaulon aquaticum is relatively pest-resistant, but it may suffer from infestations of aquatic insects such as aphids, mosquitoes, and midges. These insects feed on the plant's sap, causing stunted growth, yellowing, and curling of leaves. To manage insect pests, use insecticidal soap or neem oil, which are organic options that can effectively control the pests without harming the plant or the environment. Additionally, removing weeds and debris from the plant vicinity can help reduce the insect population.
Another pest that may affect Eriocaulon aquaticum is snails and slugs, especially in aquatic environments. These pests feed on the plant's leaves, causing irregular holes and notches on the leaves. To manage snails and slugs, remove any weeds, debris, or hiding places around the plant that may provide shelter for the pests. Handpick or trap the pests using baits such as beer traps, which can lure and drown the pests. Alternatively, apply copper-based fungicides or iron phosphate bait, which are toxic to snails and slugs but safe for the plant.
