Gotu kola
Centella asiatica

Small round leaves creeping low on moist ground, familiar in cooling drinks.
Care and placement
Likes part shade to sun, moist to wet humus-rich soil at pH 5.5–7.0; spreads by runners so trim regularly; pick outer leaves.
Draft mature dimensions
Maximum height (cm): 15 cm · Maximum spread (cm): 60 cm
Things to consider
Gotu kola is eaten and drunk in many places; use only washed leaves from clean water and unsprayed plants. Do not use it long-term as medicine; this does not replace medical advice.
How to grow and care for it
Planting and pot
Plant in part shade to sun in moist to wet, humus-rich, draining soil; mix in plenty of compost and mulch; space about 60 cm. A shallow pot or tray helps contain spread.
Light
Part shade to full sun in very moist soil; sources differ on shade — too much shade can invite pests.
Watering
Water often to keep soil moist to wet and mulch; extreme waterlogging causes root rot. Very high humidity may bring fungal disease.
Feeding
Generous compost at planting is enough. (The sources checked give no specific schedule.)
Pruning
Pinch or cut outer leaves, leaving inner ones to keep growing; trim runners regularly so it does not take over.
Propagation
Separate rooted runners in spring and replant at once in moist soil about 60 cm apart. Seed germinates slowly and erratically so division is preferred.
Pests and common problems
Spider mites, aphids and mealybugs; fungal disease if humidity is too high; root rot with extreme waterlogging.
For a bigger harvest
For plenty of leaves: constantly moist humus-rich soil, light shade, regular picking of outer leaves and trimming of runners for a steady supply of young leaves.
