Origin and Common Names
Inversodicraea fluitans H.E.Hess is a plant native to the Andes Mountains of South America, particularly in Chile and Argentina. It is known by its common names such as “Flotante” in Argentina and “Colihue Huil?” in Chile.
General Appearance
This aquatic plant belongs to the family Melastomataceae and grows as a submerged or floating plant in mountain streams, ponds, and lagoons. Its stems can grow up to 2 meters long and are commonly found floating on the water's surface. The plant has a dense, leafy coverage and produces numerous small, white flowers that appear from December to February.
Uses
The Inversodicraea fluitans has been used traditionally in Chilean culture to produce baskets, fishing nets, and various handicrafts. The leaves and stems are strong and flexible, making them ideal for weaving. Additionally, the plant's dense underwater growth provides shelter and breeding areas for fish and other aquatic animals.
The plant is not widely cultivated, but it is highly appreciated in ornamental ponds and water gardens where its floating habit and delicate flowers add to the natural beauty.
Light Requirements
Inversodicraea fluitans H.E.Hess typically grows in areas with full sunlight exposure or partially shaded areas. When planting, be sure to choose a suitable location that will provide the plant with adequate light.
Temperature Requirements
Inversodicraea fluitans H.E.Hess is a relatively hardy plant species that can thrive in a variety of temperature ranges. However, the plant prefers temperatures that range between 15°C - 25°C. The plant can also grow in cooler temperatures but might grow at a slower pace and produce fewer flowers.
Soil Requirements
Inversodicraea fluitans H.E.Hess prefers moist soils that are slightly acidic. The plant can grow in a sandy or loamy soil, but the soil must be well-draining. Adding organic matter, such as manure, compost, or peat moss, can improve soil fertility and moisture retention. Before planting, test the soil for its pH level and other nutrient content, and make necessary adjustments.
Cultivation methods
Inversodicraea fluitans is a plant that is typically grown in containers. The plant requires well-drained soil with high organic content.
The plant prefers partial shade but can tolerate full sun in some climates.
It is essential to keep the plant away from strong winds as the leaves can be easily damaged.
Watering needs
Inversodicraea fluitans requires a consistent watering schedule. The soil should be kept moist but not waterlogged. The plant prefers to be kept on the drier side during winter.
The plant should be watered from the bottom to avoid wetting the leaves, which can cause fungal infection and other diseases.
Fertilization
Periodic fertilization is necessary for Inversodicraea fluitans to thrive. The plant should be fertilized every two weeks during the growing seasons using a balanced fertilizer.
It is important to avoid over-fertilizing the plant, as this can burn the roots and weaken the plant.
Pruning
Inversodicraea fluitans requires little pruning beyond the removal of dead or diseased leaves. Deadheading flowers as they fade can improve the plant's appearance, encourage new growth, and prevent the plant from becoming too leggy.
Pinching back the growing tips of the plants can encourage bushier growth, as well as maintaining the plant's size and shape.
Propagation of Inversodicraea fluitans H.E.Hess
Inversodicraea fluitans H.E.Hess can be propagated through vegetative means such as division of mature plants or through seed. Although seed production in this plant is rare and unpredictable, propagating through division is relatively easy and is the recommended method.
Division Propagation
Division propagation involves separating the mature plant into sections and repotting each section into a new pot. This method is best done during the plant's growing season, which is typically in the spring or early summer. The plant should first be removed from its pot and the soil gently cleaned away from the roots.
Next, the plant should be divided into smaller sections, each with its own roots and a few healthy stems and leaves. The divided sections should be then potted separately into suitable containers with fresh soil and watered adequately. The new plants should then be placed in a bright, but shady location with a temperature around 68-72° F until they become established.
Seed Propagation
Propagation through seed is more unpredictable and difficult due to the plant's tendency to produce few seeds that may take a long time to germinate. However, If one desires to propagate through seed, the process should be carried out in early spring when the plant is actively growing. The seeds can be sown in pots or trays of fresh compost and kept in a warm location with adequate humidity and light.
Once the seedlings have grown to a suitable size, approximately 2-3 inches tall, they can be potted separately into small containers with fresh soil. The young plants should then be kept in a shaded location with a temperature around 68-72° F until they are strong enough to be transferred to larger containers and exposed to more sunlight.
Disease and Pest Management for Inversodicraea fluitans H.E.Hess
Inversodicraea fluitans H.E.Hess, commonly known as the floating marshpennywort, is a beautiful aquatic plant that belongs to the family Melastomataceae. As with any plant, it is susceptible to various diseases and pest infestations, which can hamper its growth and decrease its aesthetic value. Below are some of the common diseases and pests that might affect Inversodicraea fluitans, along with ways to manage them.
Diseases
1. Leaf Spot: Leaf spot is a common fungal disease that affects Inversodicraea fluitans. The symptoms include the appearance of small, circular spots on the leaves, which may turn yellow or brown over time. To manage this disease, it is recommended to avoid overhead watering, as this can create a favorable environment for the growth of the fungus. Remove the affected leaves and dispose of them properly. Fungicides can also be used to control the spread of the disease.
2. Root Rot: Root rot is a serious fungal disease that can affect the roots of Inversodicraea fluitans. The symptoms include wilting, yellowing, and stunted growth. The infected roots turn brown and slimy, eventually leading to the death of the plant. To manage this disease, it is important to provide good drainage and avoid overwatering. Remove the infected parts of the plant and replant in fresh, sterile soil. Fungicides can also be used to control the spread of the disease.
Pests
1. Aphids: Aphids are small insects that feed on the leaves and stems of Inversodicraea fluitans. The affected leaves become distorted and discolored, and the plant may show stunted growth. To manage aphid infestations, it is recommended to use insecticidal soap or neem oil. Ladybugs and other natural predators can also be introduced to control aphid populations.
2. Snails and Slugs: Snails and slugs are common pests that feed on the leaves and stems of Inversodicraea fluitans. They leave behind characteristic slime trails and irregular holes on the leaves. To manage snail and slug infestations, it is recommended to handpick and remove them from the plant. Barriers, such as copper tape, can also be used to prevent their access. Sluggo or other organic slug baits can be used to control populations.
By implementing good cultural practices, such as providing adequate water and nutrients, and promptly addressing any signs of disease or pest infestation, you can help ensure the health and beauty of your Inversodicraea fluitans plants.
