Water Alstroemeria psittacina regularly, keeping the soil consistently moist but not waterlogged, especially during its active growth period. Allow the top few centimeters of soil to dry out slightly between waterings.

Reduce watering in winter when the plant is dormant, but do not let it dry out completely.

Deadhead spent flowers regularly to encourage more blooms and maintain a tidy appearance. In late autumn or early spring, trim back any dead or damaged foliage.

Alstroemeria psittacina benefits from being divided every few years, which also acts as a form of pruning.

Alstroemeria psittacina is typically propagated by division of the rhizomes in early spring before new growth appears. Carefully separate the fleshy roots, ensuring each section has at least one bud.

Plant divisions immediately into well-draining soil.

Repot established plants every 2-3 years, preferably in early spring. Choose a pot that is only slightly larger than the current one.

Alstroemeria psittacina prefers to be slightly root-bound, so avoid oversized containers. Ensure the new pot has good drainage.
