Light Requirements
Centella lasiophylla Adamson typically grows well in partial to full shade conditions. It thrives in places with indirect light and can tolerate some hours of sunlight during the day. Direct sunlight for long periods can cause damage to the plant. It is best to place the plant near a window with a sheer curtain to filter the light, or provide shade during the hottest parts of the day if grown outside.
Temperature Requirements
The ideal temperature range for Centella lasiophylla Adamson is between 60°F to 85°F (15.5°C to 29.4°C). It can tolerate temperatures as low as 45°F (7.2°C) but this can slow down its growth. Extreme temperatures, either hot or cold, can stress the plant leading to wilting, yellowing and, ultimately, death. It's best to maintain a consistent temperature to ensure robust growth.
Soil Requirements
Centella lasiophylla Adamson requires moist and well-drained soil. It should be kept consistently moist but not waterlogged as this can lead to root rot. Use a high-quality soil mix that can retain moisture and allow for proper drainage. A pH range of 6.0 to 7.5 is ideal for this plant.
Fertilizer Requirements
For optimal growth, Centella lasiophylla Adamson requires regular fertilizing using a water-soluble or granular fertilizer every two weeks. Use fertilizers with a balanced formulation to ensure optimum growth. Overfertilizing may harm the plant leading to excess salts in the soil, causing nutrient burn. Read and follow the instructions carefully when applying fertilizer.
Cultivation methods for Centella lasiophylla Adamson
Centella lasiophylla Adamson is an easy-to-grow plant and can be cultivated both indoors and outdoors. It is usually grown from seeds or cuttings. While starting from seeds takes a longer time to grow into a mature plant, cuttings root faster and produce a lush plant over time.
For successful cultivation, it is essential to provide the plant with well-draining and nutrient-rich soil. The ideal soil pH for growing Centella lasiophylla should be slightly acidic to neutral (pH 6.5-7.5).
The plant requires a bright location, but it should be protected from intense sunlight, especially during the afternoon. It can thrive in partial to full shade, and the temperature range of 20-30°C is optimal for its growth.
Watering needs for Centella lasiophylla Adamson
Consistent watering is crucial for the healthy growth of Centella lasiophylla Adamson. It prefers moist soil and requires regular watering to prevent the soil from drying up. However, make sure not to overwater the plant, as waterlogged soil can cause root rot.
It is advisable to water the plant once or twice a week, depending on the weather and the moisture level of the soil. You can also check the soil moisture by touching the top layer of soil with your finger. If it feels dry, it is time to water.
Fertilization of Centella lasiophylla Adamson
Centella lasiophylla Adamson requires regular fertilization to thrive and maintain its lush green foliage. You should fertilize it every two to three weeks during the growing season, starting from early spring until late summer.
Use a balanced, water-soluble fertilizer with equal levels of nitrogen, phosphorus, and potassium. You can also use organic compost or manure to enrich the soil with organic matter and essential nutrients.
Pruning of Centella lasiophylla Adamson
Pruning is essential to keep the Centella lasiophylla plant healthy and maintain its shape. It also promotes new growth and helps to remove any dead or damaged leaves and stems.
You can prune the plant at any time of the year, but it is advisable to do it during the growing season. You can trim the plant using sharp and clean pruning shears.
Pruning should not involve removing more than one-third of the plant at a time. Also, make sure to leave some leaves and stem intact to allow the plant to continue photosynthesizing.
Propagation methods of Centella lasiophylla Adamson
Centella lasiophylla Adamson is commonly known as the hairy marsh pennywort. The propagation of Centella lasiophylla Adamson can be carried out through several methods, which include:
Seed propagation
Seeds are the primary means of propagation for Centella lasiophylla Adamson. The seeds are small and can be collected from the mature plant.

It can take up to eight weeks for the seeds to germinate, and it is important to ensure that the environmental conditions are optimal for germination.
Cuttings propagation
Propagation of Centella lasiophylla Adamson through cuttings is also possible. Cut a section of the stem with at least two nodes and remove the lower leaves. Dip the base in a rooting hormone to improve the chances of rooting. Plant the cutting in a well-draining moist soil mixture and keep it out of direct sunlight. After a few weeks, roots will develop, and the plant will establish itself.
Division propagation
Centella lasiophylla Adamson can also be propagated through division. Divide an established plant by carefully separating the roots and the leaves. Plant each division in a well-draining soil mixture and keep it moist. It is important to ensure that the divided plant is not exposed to direct sunlight until it has established itself.
Conclusion
Centella lasiophylla Adamson can be propagated through various methods, including seed propagation, cuttings propagation, and division propagation. Each propagation method has its advantages and disadvantages, but with proper care, the plant will establish itself in no time.
