Lindernia Rotundata (pilg.) Eb.fisch.

Description of Lindernia Rotundata

Lindernia rotundata (Pilg.) Eb. Fisch. is a small, creeping herbaceous plant native to Tropical Africa. It is commonly known as the round-leaved or button weed. The plant is often found in swampy areas, damp soils, and along stream banks where it grows best in full sun.

General Appearance of Lindernia Rotundata

Lindernia rotundata has a prostrate growth habit, with stems that are often creeping above ground and rooting at the nodes, giving rise to a dense mat of vegetation. The leaves are round or elliptic-shaped, with serrated edges and are about 5-12 mm long. The flowers of Lindernia rotundata are small, tubular and white in color, often borne in clusters of two or three.

Traditional Uses of Lindernia Rotundata

Lindernia rotundata has been traditionally used for medicinal purposes in some African countries. The plant has been used to treat various ailments including stomach problems, fever, and headaches. Its leaves have also been used externally to treat skin infections, burns, and wounds.

Additionally, Lindernia rotundata is also used in aquariums as an ornamental plant. Due to its size, it is suitable for use in small aquariums and as a foreground plant in larger aquariums.

Conclusion

In summary, Lindernia rotundata is a small, creeping herbaceous plant with round or elliptic-shaped leaves. It is commonly found in swampy areas, damp soils, and along stream banks. The plant has been traditionally used for medicinal purposes in some African countries and is also used in aquariums as an ornamental plant.

Growth Conditions of Lindernia rotundata

Lindernia rotundata (Pilg.) Eb.Fisch., commonly known as Roundleaf Lindernia, is a small aquatic plant that has become popular among aquarists. It is native to South-East Asia, where it can be found growing submerged in shallow, slow-moving streams, rivers, and rice paddies. Here, we will discuss the typical growth conditions that Lindernia rotundata requires for optimal growth.

Light Requirements

Light is one of the most critical factors for the growth of Lindernia rotundata. It requires moderate to high levels of light to perform its photosynthesis efficiently and produce energy. In aquariums, it is recommended to provide approximately 2-3 watts of light per gallon of water. The light must be provided for at least 8-10 hours per day to ensure healthy growth. However, excessive lighting can cause algae growth on the leaves, to prevent this, it is suggested to use a timer to control the lighting period.

Temperature Requirements

The sub-tropical temperature range is best suited for the growth of Lindernia rotundata. It grows well in water that is kept at a temperature range of 22-28 °C (72-82°F). Temperatures above 30°C can lead to heat stress and cause the leaves to bleach. Moreover, the plant can tolerate minor temperature fluctuations, but drastic fluctuations and prolonged exposure to extreme temperatures can cause plant damage. Therefore, it is important to maintain a consistent water temperature to ensure healthy growth of the plant.

Soil and Water Requirements

Lindernia rotundata prefers soil that is rich in essential nutrients. In an aquarium, it is recommended to use a nutrient-rich substrate such as aqua soil. The plant grows well in soft, slightly acidic to neutral water with a pH range of 5.8-7.5. The optimal water hardness for Lindernia rotundata is between 3-10°KH and 2-10°GH. The plant requires adequate levels of water movement to provide a proper supply of dissolved CO2. It is suggested to use a higher flow filter to ensure water movement around the plant. Furthermore, regular water changes (20-30%) once a week are required to remove accumulated nitrate and other waste products, which can affect plant growth.

In summary, providing optimal light, temperature, and adequate nutrients and water parameters will help ensure healthy growth of Lindernia Rotundata.

Cultivation

Lindernia rotundata is native to Africa and can grow up to 12 inches in height. It is a semi-aquatic plant that prefers to grow in moist soils. The plant can tolerate both full sun and partial shade. Therefore, it is adaptable to different climatic conditions. It can be propagated by seeds or cuttings.

Watering needs

Lindernia rotundata requires regular watering to maintain its moist soil requirement. It prefers being watered with a gentle stream of water to avoid damaging its roots. The plant cannot survive in completely dry soil but cannot tolerate waterlogged conditions, which can cause root rot.

Fertilization

To maintain the healthy growth and vibrant foliage of Lindernia rotundata, you can fertilize the plant every month. Use a balanced formula fertilizer with an NPK ratio of 10:10:10 or a low nitrogen ratio of 2:1:1. You can use a slow-release fertilizer or a liquid fertilizer that can be diluted and poured into the soil around the plant.

Pruning

Pruning is an essential step in maintaining the shape and health of Lindernia rotundata. You can trim the plant's excess growth and shape it by cutting back the top of the plant using clean shears. You should prune at the beginning of the growing season, and avoid cutting back more than one-third of the plant's height at a time. Deadheading, the removal of spent flowers, is also necessary to encourage the growth of new flowers.

Propagation of Lindernia rotundata

Lindernia rotundata can be propagated through both seeds and vegetative means. Here are the different propagation methods:

Propagation by seeds

The seeds of Lindernia rotundata are small and can be easily collected from the mature plants. The seeds should be sown on the surface of the soil and should not be buried. The ideal time for sowing seeds is during the rainy season. The germination time is usually within 2-3 weeks.

Propagation by cuttings

Lindernia rotundata can also be propagated through stem cuttings. The cuttings should be taken from the mature plants, and the lower leaves should be removed. The cuttings should be planted in moist soil, and the soil should be kept moist until the cuttings start to root. Once the cuttings have rooted, they can be transplanted to their permanent location.

Propagation by division

Another way to propagate Lindernia rotundata is by dividing the mature plants. This method is especially useful for plants that have become too large or need rejuvenation. The plant can be carefully removed from the soil and divided into smaller parts. Each part should have roots and stems. The divided plants can be planted in separate containers or in different locations in the garden.

Disease Management for Lindernia Rotundata (Pilg.) Eb.Fisch.

Lindernia rotundata is prone to some diseases that can stunt the plant's growth and reduce its overall health. One common disease is root rot, which is caused by overwatering or poor drainage. If the roots become mushy and dark, it is recommended to remove the affected plant parts and repot in fresh soil with proper drainage. Fungal diseases can also affect this plant, often manifested through leaf spots. In such a case, removing the affected leaves and spraying the plant with a fungicide can help reduce further infection.

Pest Management for Lindernia Rotundata (Pilg.) Eb.Fisch.

There are several pests that can harm Lindernia rotundata, including spider mites, aphids, and mealybugs. Spider mites are one of the most common pests for this plant and cause webbing across the leaves. To get rid of them, removing the affected areas and washing the plants with a water hose or soap solution can control the infestation. Aphids and mealybugs can be treated with insecticidal soap or neem oil spray that can be applied to the plant regularly for better results.
