Loasa triloba prefers consistently moist soil but dislikes waterlogged conditions. Water thoroughly when the top 2-3 cm of soil feels dry. Reduce watering during winter dormancy. Ensure good drainage to prevent root rot.

Overwatering can lead to fungal diseases, so err on the side of slightly drier rather than too wet.

Prune Loasa triloba in early spring before new growth begins to encourage bushier growth and maintain shape. Remove any dead, damaged, or crossing branches. Pinch back the tips of young plants to promote branching.

Light pruning can also be done after flowering to tidy up the plant.

Propagate Loasa triloba from seeds sown in spring or from semi-hardwood cuttings taken in summer. Seeds should be sown in a well-draining seed-starting mix and kept moist and warm.

Cuttings should be placed in a moist medium and kept in a humid environment until rooted.

Repot Loasa triloba every 2-3 years in spring, or when the plant becomes root-bound. Use a well-draining potting mix, such as a blend of potting soil and perlite or sand.

Choose a pot that is only slightly larger than the current one to avoid overwatering. Water gently after repotting.
