Water Colliguaja dombeyana regularly during the growing season, allowing the soil to dry out slightly between waterings.

Reduce watering significantly in winter, providing just enough to prevent the soil from becoming completely dry. Ensure good drainage to prevent root rot.

Pruning Colliguaja dombeyana is generally minimal. Remove any dead, damaged, or crossing branches as needed. Light shaping can be done after flowering to maintain a desirable form.

Avoid heavy pruning, as it may not recover well.

Propagation of Colliguaja dombeyana is best achieved through semi-hardwood cuttings taken in summer. Root the cuttings in a well-draining medium under humid conditions.

Seed propagation is also possible but can be slow and less reliable for true-to-type plants.

Repot Colliguaja dombeyana when the plant becomes root-bound, typically every 2-3 years. Use a well-draining potting mix, such as a blend of peat, perlite, and coarse sand.

Repot in early spring before new growth begins to minimize transplant shock.
