III. Proper soil and water
Araucaria prefers a humid environment but is not drought-tolerant. It is recommended to use pine needle soil or peat moss as the substrate, adding an appropriate amount of leaf mold or perlite, etc., to keep the soil moist but not waterlogged. When watering, the amount and frequency should be adjusted according to different seasons and temperatures.
IV. Pay attention to pest control

VI. Timely pruning and adjustment of placement
Araucaria bonsai requires regular pruning and adjustment of its placement to maintain a beautiful tree shape. When pruning, attention should be paid to the aesthetic shape of the branches, and old and diseased branches should be pruned regularly and disposed of in a timely manner.
