- Propagation through stolons: Centella eriantha var. rotundifolia spreads through stolons. These stolons can be cut and replanted in a new location. The stolons should be planted in well-draining soil and watered regularly until they establish roots.
- Soil requirements: Centella eriantha var. rotundifolia prefers moist soil that is well-draining. The soil should be rich in organic matter and should have a slightly acidic pH.
- Light requirements: Centella eriantha var. rotundifolia prefers partial shade to full shade. The plant can grow in direct sunlight but may require more water.
Watering needs for Centella eriantha (Rich.) Drude var. rotundifolia Adamson
Water pennywort, like most other plants, requires regular watering for proper growth and development. Here are some watering needs for Centella eriantha var. rotundifolia:
- Centella eriantha var. rotundifolia requires moist soil for proper growth. The soil should be kept moist at all times, especially during dry periods.
- Overwatering should be avoided as it can lead to root rot and other fungal diseases.
- If the plant starts to wilt, it may indicate that it is not getting enough water.
- The plant can be grown in water gardens and should be submerged in shallow water to a depth of 5-10 cm.

- The plant can also benefit from an organic fertilizer such as compost or manure.
- Fertilizers should be applied according to the manufacturer's instructions.
- Overuse of fertilizers can lead to excessive growth and may damage the plant.
Pruning for Centella eriantha (Rich.) Drude var. rotundifolia Adamson
Pruning is necessary for the healthy growth of Centella eriantha var. rotundifolia. Here are some pruning guidelines:
- Dead and damaged leaves should be removed regularly to prevent the spread of disease.
- The plant can be pruned in late winter or early spring to promote new growth.
- The plant can be trimmed back to control its size and prevent it from becoming invasive.
- Pruning should be done with clean and sharp tools to avoid damaging the plant.
Propagation of Centella eriantha var. rotundifolia Adamson
Centella eriantha is a fast-growing herbaceous plant found in tropical regions across the world, including Asia, Africa, and South America. The plant has a reputation for its medicinal properties, leading to its increased cultivation in recent years.
Propagation by Seeds
The most common method of propagation for Centella eriantha is by seed. The seeds are small in size and require careful handling during sowing to avoid losing their viability.
The seeds should be collected from mature plants and dried before sowing. They are then sown in a seedbed with a suitable potting mix. The seedbed should be kept moist, but not waterlogged, and placed in a shaded area to protect the seeds from direct sunlight.
The seedlings should emerge within two to four weeks. Once they are large enough, they can be transplanted to individual pots or directly into the ground. It is recommended to transplant the seedlings during the rainy season, as this will help to establish them quickly.
Propagation by Cuttings
Centella eriantha can also be propagated by cuttings. This method is used to propagate plants that have desirable traits, such as those with high medicinal value.
The stem cuttings should be taken from a healthy, mature plant and should be around 10-20cm in length. The lower leaves should be removed, and the cuttings should be dipped in a rooting hormone before being planted in a potting mix.
The potting mix should be kept moist and the cuttings should be placed in a shaded area to avoid direct sunlight. Rooting should occur within two to four weeks, at which point the cuttings can be transplanted.
Propagation by Division
Centella eriantha can also be propagated by division. This method involves separating the plant into smaller sections and replanting them.
To propagate by division, the plant should be dug up and the roots carefully separated into smaller sections. These sections should have at least one healthy shoot and a good root system. The separated sections can then be replanted into pots or directly into the ground.
Propagation by division is best done during the rainy season, as this will help the newly planted sections establish themselves quickly.
Disease management
Centella eriantha (Rich.) Drude var. rotundifolia Adamson is a relatively disease-resistant plant. However, there are a few diseases that may affect the plant and reduce its yield and quality. The following are some common diseases and their management:
- Leaf Spot: This disease is characterized by small, circular spots on the leaves, which later turn brown. To manage leaf spot, remove infected leaves and treat the plant with a copper-based fungicide.
- Powdery Mildew: Powdery mildew is a fungal disease that affects the leaves and stems of the plant. The affected parts are covered with a white, powdery coating. To manage powdery mildew, prune the affected parts, improve air circulation and treat the plant with a sulfur-based fungicide.
- Yellow Leaf Curl: This virus is transmitted by whiteflies and causes the leaves to curl and turn yellow. To manage yellow leaf curl, control whiteflies using insecticides and remove infected plants to prevent the spread of the virus.
Pest management
Centella eriantha (Rich.) Drude var. rotundifolia Adamson may also be affected by pests. The following are some common pests and their management:
- Spider Mites: These pests are tiny and difficult to see but can cause significant damage to the plant by sucking sap from the leaves. To manage spider mites, spray the plant with a soap-based insecticide and maintain proper humidity levels.
- Aphids: Aphids are small, pear-shaped insects that can cause deformation of the leaves and stems. To manage aphids, control their population with insecticides or release natural predators such as ladybugs and lacewings.
- Caterpillars: Caterpillars are the larval stage of butterflies and moths and can cause significant damage to the plant by feeding on the leaves. To manage caterpillars, remove them from the plant by handpicking or using an insecticide that targets caterpillars.
