If you want to make Araucaria bonsai thrive at home, proper maintenance is the key. This article will introduce you in detail the maintenance methods of Araucaria bonsai and help you easily raise beautiful Araucaria bonsai. Light and temperature Araucaria likes light, but is also resistant to shade. It is suitable for placing in a bright place indoors but not direct sunlight. When high temperatures in summer, shade should be properly covered to avoid sunburn on the leaves. In winter, sufficient sunshine should be ensured to promote its growth. The optimal temperature for Araucaria growth is 18-25℃, and the room temperature in winter should not be lower than 5℃. Watering and soil Araucaria likes to be moist but is not resistant to waterlogging. Watering must adhere to the principle of "seeing wet when it is dry". Spring and autumn are periods of vigorous growth and require a large amount of water. In summer and winter, watering frequency should be appropriately reduced. In terms of soil, Araucaria is suitable for growing in slightly acidic soil with good drainage and strong air permeability. It can be prepared by mixing materials such as legus soil, peat soil and perlite. Fertilization and pruning During the growth of Araucaria, compound fertilizer or organic fertilizer should be applied once a month to provide sufficient nutrients. Pay attention to the concentration when fertilizing to avoid excessive root burning. For branches that grow too fast, pruning should be carried out in time to maintain the tree shape. Beautiful, charcoal powder or gardening glue should be applied to pruned wounds in time to prevent the invasion of bacteria. Pest and pest control Common pests and diseases in Araucaria bonsai include scale insects, red spiders, etc. The control methods are as follows: 1. Regularly inspect the leaves and remove pests and diseases in time when found; 2. Use pesticides to control, such as imidacloprid, avermectin, etc.; 3. Maintain indoor ventilation to reduce the occurrence of pests and diseases. Pots and soil changes After the Araucaria bonsai has grown for a period of time, pots and soil changes need to be carried out, usually every 2-3 years. When changing pots, choose a flower pot larger than the original pot and use new culture soil. When changing soil, take out the plant together with the roots, clean up the old soil, cut off the dead roots and rotten roots, and then plant it again.
The maintenance of Araucaria bonsai is not complicated. As long as you master the key points of light, temperature, watering, fertilization, pruning and pest and disease control, you can make your Araucaria bonsai rejuvenate at home. Araucaria bonsai also purifies the air and beautifies the environment. It is an ideal choice for home cultivation.
