Growth Conditions for Eleocharis acicularis var. radicans
Eleocharis acicularis var. radicans is a freshwater plant that is commonly found in shallow, still or slow-moving waters of ponds, lakes, and streams. The plant has a horizontal rhizomatic structure with a bunch of grass-like stems. The ideal growing conditions for this plant include:
Light Requirements
The plant requires moderate to high light to grow and flourish. When planted in areas with low light, the plant tends to grow taller as it tries to reach for more light. If planted in direct sunlight, the plant may experience leaf-burn and discoloration. The ideal location for Eleocharis acicularis var. radicans would be an area with partial shading or filtered sunlight.
Temperature Requirements
This plant grows best in a temperature range between 18°C and 28°C. It can still grow in temperatures of up to 35°C and as low as 10°C. However, the lower the temperature, the slower the plant's growth will be. Therefore, the ideal temperature range for Eleocharis acicularis var. radicans would be between 18°C and 28°C.
Soil Requirements
Eleocharis acicularis var. radicans can excel in a variety of soils, including clay, sand, and loam. However, the preferred soil condition for this plant is nutrient-rich, slightly acidic, with a pH range of 6.5-7.5. The soil should also be moist but not waterlogged, with good drainage to avoid water stagnation, which may lead to decaying of the plant.
In conclusion, providing sufficient light, moderate temperature within the range of 18°C and 28°C, and a nutrient-rich slightly acidic soil with good drainage will ensure the successful growth and development of Eleocharis acicularis var. radicans.
Cultivation Methods
Eleocharis acicularis var. radicans can be grown in two ways, i.e., through seeds or vegetative propagation. For seed propagation, you need to sow the seeds in the substrate and let them grow on their own. However, vegetative propagation involves dividing an already grown plant into several parts and replanting them in different pots. The species prefer a temperature range of 18-26°C and requires moderate lighting.
Watering Needs
The plant is shallow rooted and, therefore, requires frequent watering. Its substrate should remain moist enough to provide a constant supply of water to the plant's roots. However, overwatering must also be avoided as it can lead to rotting of the roots.
Fertilization
The Eleocharis acicularis var. radicans is a heavy feeder and requires regular fertilization to achieve optimal growth and health. A well-balanced liquid fertilizer can be used twice a week to provide the necessary nutrients. Ensure that you do not overdose the fertilizers or allow them to come into contact with the leaves, as it can burn the plant.
Pruning
Regular pruning ensures the plant stays healthy and attractive. You should trim off any yellowing and decaying leaves and stems using a sharp pair of scissors or pruning shears. Additionally, overgrowth must also be cut off to maintain the desired shape of the plant. You should avoid pruning more than a third of the plant at any given time, as this can lead to stunted growth.
Propagation of Eleocharis acicularis var. radicans
Eleocharis acicularis var. radicans, commonly known as rooted dwarf hairgrass, can be propagated through different methods. The most common propagation methods are by runners and dividing the plant.
Propagation by runners
Propagation by runners is the easiest and quickest method for Eleocharis acicularis var. radicans. Runners are thin, elongated stems that grow horizontally on the substrate. When they reach a certain length, they produce new plantlets at their nodes, which can be separated from the main plant and grown into new plants.
To propagate by runners, it is necessary to trace the runner's path and find the node where the new plantlet has emerged. Then, using sharp scissors or pruning shears, cut the node, leaving a small portion of the runner attached to the plantlet. This portion will help the plantlet to attach to the substrate and grow roots.
Propagation by dividing the plant
Propagation by dividing the plant is a more laborious method. It requires digging out the plant, dividing it into smaller portions, and replanting the portions in a new location. This method is recommended for older plants that have developed a thick and dense mat of roots.
To propagate by dividing the plant, first, remove the plant from the substrate, and gently separate the mat of roots into smaller portions using your fingers or a sharp knife. Make sure that each portion has enough roots and foliage to support its growth. Then, replant each portion in a new location, keeping the roots submerged in the substrate.
Disease Management
Eleocharis acicularis var. radicans is relatively disease resistant but may still succumb to certain diseases. The plant may develop root rot, which is a result of overwatering and poorly drained soil. Root rot can be managed by reducing watering frequency and improving the drainage of the soil.
Another common disease that may affect Eleocharis acicularis var. radicans is brown algae. Brown algae can be identified by its brown color and slimy appearance. It can be managed by improving water circulation and ensuring that there is enough light in the aquarium. Additionally, regular water changes and cleaning the aquarium regularly can help prevent the growth of brown algae.
Pest Management
In addition to diseases, Eleocharis acicularis var. radicans is susceptible to various pests. One of the most common pests that affect the plant is the snail. Snails can be detrimental to the growth of the plant as they feed on it and can cause significant damage. Snails can be removed manually or by using a snail trap.
Another common pest that may affect Eleocharis acicularis var. radicans is the fish louse. Fish lice are parasitic and can be identified by their small size and oval shape. They can be removed manually or by treating the aquarium with an appropriate parasite medication.
Finally, spider mites may also affect Eleocharis acicularis var. radicans. Spider mites are identified by the presence of webbing and tiny bumps on the leaves. They can be managed by regularly washing the leaves of the plant with water or by using an appropriate insecticide.
