How to Grow Katuk
Sauropus androgynus
Katuk thrives in warm, humid conditions with partial shade to full sun and regular moisture. Plant in well-drained, fertile soil and water consistently. Harvest young shoot tips regularly to keep the plant bushy and productive. In temperate climates, grow in a container and bring indoors before the first frost. Feed monthly with a nitrogen-rich fertiliser through the growing season.
Yearly Lifecycle
Care Essentials
Apply a balanced fertiliser in spring when new growth appears, then monthly through the growing season with a nitrogen-rich feed to support leafy growth.
Watch For
- Spider mites in dry conditions
- Aphids on young shoots
- Root rot in waterlogged soil
- Caterpillars on leaves
Care Requirements
Light
Partial shade to full sun
Katuk tolerates a wide light range. It grows fastest in full sun with adequate moisture, but thrives in partial shade — particularly useful in humid climates with intense afternoon sun. Avoid deep shade which reduces leaf production.
Watering
Regular moisture; do not let dry out
Water consistently to keep the soil evenly moist but not waterlogged. Katuk is a thirsty plant in full sun and hot conditions. Mulch around the base to retain moisture. Reduce watering in cooler or dormant periods.
Fertilizing
Monthly nitrogen-rich feed during growing season
Apply a balanced fertiliser at the start of spring growth. Switch to a nitrogen-rich liquid feed monthly through summer and early autumn to support heavy leaf production. Avoid over-feeding with high-phosphorus fertilisers.
Pruning
Prune to one third in late winter; harvest tips regularly
Cut stems back by one third in late winter or early spring to promote dense bushy regrowth. Regular harvesting of young shoot tips throughout the season acts as continuous light pruning and keeps the plant productive.
