How to Care for Gotu Kola

Gotu kola (Centella asiatica) is a low, creeping perennial groundcover with fan- or kidney-shaped bright green leaves on slender stems that root at the nodes as they spread. It thrives in warm, moist, humid conditions and makes an easy, fast-filling mat in the right site.

Light

Gotu kola grows in partial shade to full sun. It is happiest in bright, dappled light or morning sun with afternoon shade, especially in hot climates where full midday sun can scorch the tender leaves unless soil stays wet. In cooler, humid conditions it takes more sun. Deep shade slows and thins the mat.

Water

Keep the soil consistently moist; this is a plant of damp margins and pond edges and it will not tolerate drying out. It loves reliably wet, even boggy conditions and wilts quickly when thirsty. Frequent watering, or a naturally moist site, keeps the foliage plump and spreading.

Soil & Potting

Use a rich, moisture-retentive soil that stays damp but is not stagnant. Loamy, organic-rich mixes are ideal; it tolerates heavy soils that hold water. In containers, a peat- or coir-based potting mix works well, and standing the pot in a shallow saucer of water helps keep the roots moist.

Humidity & Temperature

Gotu kola is a tropical to subtropical plant that loves warmth and high humidity, thriving in temperatures around 20-30C (68-86F). It is frost-tender and stops growing or dies back in cold. Indoors or in dry climates, boost humidity and keep it out of cold drafts.

Feeding

Feed lightly during active growth with a balanced or nitrogen-leaning fertilizer to fuel leafy spread; a diluted liquid feed every few weeks in the growing season keeps the mat vigorous. Rich, organic soil reduces the need for supplemental feeding. Avoid heavy feeding, which is unnecessary for this modest plant.

Propagation

Gotu kola is extremely easy to propagate. Its runners root at the nodes, so simply lift and divide rooted plantlets and replant them, or peg runners down until they root. It can also be grown from seed, but division of the naturally rooting stems is faster and reliable.

Repotting / Pruning

Repot or divide crowded containers each spring, since it fills a pot quickly. Trim back runners any time to keep it in bounds, as it spreads enthusiastically. Cutting it back also refreshes the foliage and encourages dense new growth.

Common Problems & Pests

The main problems come from letting it dry out, which causes rapid wilting and leaf loss. In stagnant, airless conditions fungal leaf spots or root rot can develop, so keep moisture high but not stagnant. Aphids, whiteflies, and spider mites may appear, especially indoors in dry air; rinse foliage and raise humidity to deter mites.

Seasonal Care Tips

Growth surges in warm, humid weather; this is when to divide, feed, and let it spread. In winter or cold snaps protect it from frost, bring containers indoors, and reduce watering as growth slows. Resume regular moisture and feeding when warmth returns.
