1、 Breeding environment

1. Soil: loose and fertile loam is the best soil for Araucaria

2. Light: it shall be maintained outdoors in spring and autumn to avoid the sunlight at noon. In summer, it shall be properly shaded to avoid the sun exposure

3. Watering: the humidity of its basin soil should not be less than 70%, which is conducive to its good growth

4. Fertilization: it grows vigorously, so we should apply more fertilizer. We can only apply rotten and thin fertilizer 1-2 times a month to make it grow healthily

2、 Breeding method

1. Cutting propagation: generally, it is carried out in spring and summer festivals. Select strong and powerful stems and disinfect them before cutting. The soil should be kept at about 70% moderate. Pay attention to management and protection at ordinary times. It can take root and survive after 4 months

2. Sowing and reproduction: firstly, grind the seed coat to reduce its germination time. Secondly, disinfect the soil to avoid the invasion of diseases

3、 Common diseases and insect pests

For example, the harm of scale insects can be controlled with 40% Omethoate 1000 ~ 1500 times solution

4、 Precautions

1. Pruning: the lower branches of Araucaria lanceolata are easy to wither and fall off, so it should be pruned properly to ensure beautiful plant shape

2. Change the basin: change the basin once every 2-3 years. After changing the basin, you can't see the direct sunlight immediately. You should let it radiate the scattered light first
