Propagation of Echinodorus tenellus (Mart.) Buch. var. latifolius (Seub.) Fassett
Echinodorus tenellus (Mart.) Buch. var. latifolius (Seub.) Fassett, commonly known as Pygmy Chain Sword, is a freshwater aquatic plant often used in aquariums and aquascapes. It is native to South America, particularly in Brazil, Paraguay, and Argentina. Propagation of this plant is important to maintain its growth and form a green carpet over the substrate.
Division
One of the easiest ways to propagate Pygmy Chain Sword is through division. The plant forms runners with small plantlets at the end, which can be carefully removed from the mother plant using scissors or tweezers. It is essential to ensure that each plantlet has a healthy root system. The new plantlets can then be planted in separate areas, preferably with nutrient-rich substrate, and sufficient lighting and carbon dioxide supply.
Seeds
Although Pygmy Chain Sword can produce flowers and fruits, it is uncommon for the plant to produce seeds in the aquarium setting. However, if seeds are available, the plant can be propagated by sowing the seeds in a cultivated substrate. It is essential to maintain a high level of moisture and humidity for the seeds to germinate. The young seedlings can be transferred into individual pots until they are sturdy enough to replant into the aquarium.
Plantlets formation
Pygmy Chain Sword plantlets can also be formed through the artificial induction of runners. To do this, select a healthy mother plant, and cut off or trim back the leaves and roots to promote the growth of the runner. Provide adequate light and carbon dioxide supply to the plant, and wait for the formation of plantlets at the end of the runner. Alternatively, the mother plant can be placed in a separate container with rich substrate to help runners form and produce plantlets.
Disease Management
Echinodorus tenellus var. latifolius is generally resistant to diseases. However, it is susceptible to certain fungal and bacterial infections like Pythium spp., Rhizoctonia spp., and bacterial soft rot. These diseases are often caused by soil-borne pathogens.
To prevent fungal infection, it is recommended to avoid overwatering, facilitate proper air circulation, and use pathogen-free potting soil. Infected plants should be promptly removed and destroyed to prevent the spread of the disease. Treating the soil with a fungicide can also help to control fungal infections.
Bacterial soft rot affects the roots and stems of the plant, leading to decay and ultimately death. The best way to prevent this disease is to maintain good hygiene practices, which include disinfecting gardening tools and containers. Infected plants should also be removed immediately and destroyed. In severe cases, the use of antibiotics may be necessary, although prevention is the best approach.
Pest Management
Echinodorus tenellus var. latifolius is generally resistant to pests. However, like any other plant, it can fall prey to certain pests like aphids, snails, and slugs.
Aphids are tiny, soft-bodied insects that suck sap from the plant, leading to stunted growth and deformation. They can be controlled by spraying insecticidal soap or neem oil on the affected leaves. Beneficial insects like ladybugs and lacewings can also help to control aphid populations.
Snails and slugs feed on the leaves and stems of the plant, leaving holes and chew marks. Copper tape or mesh around the base of the plant can help to repel these pests. Alternatively, applying diatomaceous earth or sprinkling coffee grounds around the plant can also be effective in deterring them. Handpicking and removing snails and slugs can also be an effective control method.
Regular monitoring and maintenance practices can help to prevent both diseases and pests. Keeping the plant healthy and addressing any issues promptly can lead to a thriving Echinodorus tenellus var. latifolius.
