Light Requirements
Centella glabrata L. var. glabrata typically grows best in partial shade to full shade conditions. Exposure to direct sunlight for extended periods can result in scorched leaves and stunted growth. In indoor settings, placing the plant near a north-facing window or in a shaded area of the room can provide adequate light.
Temperature Requirements
The ideal temperature range for Centella glabrata L. var. glabrata is between 18°C to 30°C (64°F to 86°F). Temperatures that fall below 15°C (59°F) or above 35°C (95°F) can adversely affect plant growth. In regions with extremely cold winters or hot summers, it is advisable to cultivate the plants in indoor settings under controlled temperature conditions.
Soil Requirements
The plant prefers moist, well-drained soil, with a slightly acidic to neutral pH range of 5.5 to 7.0. The soil mixture should be enriched with organic matter such as compost or peat moss. Sandy loam soil is ideal for the growth and spread of the plant's roots. The soil should not be allowed to dry out completely, as this can lead to wilting and damage to the plant's tissues.
Cultivation Methods
Centella glabrata L. var. glabrata, commonly known as Indian pennywort or Asiatic pennywort, is a perennial herb that prefers a warm, humid climate. It thrives in moist soil, but it should not be planted in waterlogged soil. The plant can be propagated through seeds or cuttings. If using seeds, sow them in seedbeds in the spring or early summer. Alternatively, take stem cuttings from mature plants and plant them directly in the soil or in pots filled with a suitable growing medium.
Watering Needs
The soil should be kept consistently moist but not waterlogged. Avoid letting the soil dry out completely, as this can cause the plant to wilt and die. Watering should be done regularly during periods of drought or hot weather. However, be careful not to overwater, as this can lead to root rot.
Fertilization
Centella glabrata does not require heavy fertilization, but it benefits from occasional nutrient boosts. Use a balanced fertilizer, applied at half-strength, every two to four weeks during the growing season. Be careful not to over-fertilize, as this can lead to excess foliage growth and detract from the plant's medicinal properties.
Pruning
Centella glabrata benefits from regular pruning, which helps to keep the plant compact, prevent excessive growth, and promote bushiness. Pruning should be done in the early spring or late fall, before the plant enters its resting period. Use clean, sharp shears to remove any dead or yellowed foliage, as well as any long stems or shoots that have become too leggy. Pruning will also promote the growth of new shoots, which can be harvested for their medicinal properties.
Propagation of Centella glabrata L. var. glabrata
Centella glabrata L. var. glabrata, commonly known as Asiatic pennywort, is a medicinal herb that belongs to the Apiaceae family. It is a perennial plant that thrives in moist, shady areas and is native to tropical and subtropical regions of Asia, Africa, and America.
Seed Propagation
The most common method of propagating Centella glabrata is through seeds. The seeds of Centella glabrata are small and should be sown on the surface of a good quality seed-starting mix. To improve germination rates, soak the seeds in water for 24 hours before sowing. Keep the soil moist, and maintain the temperature between 68-77°F (20-25°C). Germination can occur within 2-3 weeks after sowing.
Cuttings Propagation
Another method of propagating Centella glabrata is through cuttings. Collect stem cuttings from healthy plants, preferably in the early morning when the temperature is cooler. Cuttings should be 6-8 inches long and should have at least 2 nodes. Dip the base of the cutting in rooting hormone, and insert it into a well-draining potting mix. Keep the soil moist and the cutting in a shaded area. New roots will start to form in 2-3 weeks.
Division Propagation
Centella glabrata can also be propagated through division. This method is best done in the spring when the plant starts to grow actively. Gently dig up the clump of the plant, and divide it into smaller sections, making sure each section has enough roots and healthy stems. Replant the sections into well-draining soil, keeping the soil moist and shaded until new growth appears.
Regardless of the propagation method used, Centella glabrata requires moist, well-draining soil, and a shaded area for optimal growth. Proper care and maintenance of the plants ensure healthy growth and successful propagation.
Disease and Pest Management for Centella glabrata L. var. glabrata

It is native to Asia and is commonly used in traditional medicine to treat various ailments like anxiety, depression, and hypertension. However, like any other plant, this species is also susceptible to diseases and pests that can significantly affect its growth and productivity. Here are some of the most common diseases and pests that affect Centella glabrata L. var. glabrata and how to manage them.
Diseases
Centella glabrata L. var. glabrata is susceptible to various fungal and bacterial diseases that can cause significant damage to the plant if not managed effectively. Here are some of the common diseases that affect this plant:
Leaf spots
Leaf spots are caused by fungal pathogens that infect the leaves, causing circular or irregular-shaped spots. These spots can be of different colors, including brown, gray, or black, depending on the type of fungus. To manage leaf spots, it's essential to remove and destroy infected leaves to prevent the spread of the disease. You can also use fungicides to control the spread of the disease.
Root rot
Root rot is a common problem in Centella glabrata L. var. glabrata that is caused by different pathogens, including fungi and bacteria. It affects the roots, causing them to rot and decay, leading to stunted growth or death of the plant. To manage root rot, it's essential to avoid over-watering the plant and ensure the soil is well-drained. Also, use fungicides to control the spread of the disease.
Pests
Centella glabrata L. var. glabrata is also susceptible to various pests that can cause damage to the plant. Here are some of the common pests that affect this plant:
Spider mites
Spider mites are common pests that suck sap from the leaves, causing them to turn yellow or brown. They also produce webbing that can cover the leaves, making them look unsightly. To manage spider mites, you can use insecticidal soap or neem oil to kill them.
Leafhoppers
Leafhoppers are small, wedge-shaped insects that feed on the leaves, causing them to turn yellow or brown and become distorted. They also produce honeydew that attracts ants. To manage leafhoppers, you can use insecticides or neem oil to kill them.
Cutworms
Cutworms are the larvae of various moth species that feed on the plant's stem, causing them to wilt or die. To manage cutworms, you can use Bacillus thuringiensis (Bt) or spinosad insecticides to kill them.
By managing diseases and pests that affect Centella glabrata L. var. glabrata, you can keep the plant healthy and productive. It's essential to monitor the plant regularly for signs of diseases or pests and take appropriate action before they cause significant damage.
