1、 Curing method

1. Temperature: Araucaria likes a slightly higher temperature, between 25 and 30 degrees, which is the most suitable. However, too hot season is not conducive to its growth. Therefore, when the temperature is higher than 35, try to adjust it. In addition, it is a very cold resistant plant, which basically does not need to be adjusted in winter

2. Light: Araucaria is a light loving species. However, it needs to be shielded from too strong light, and exposure to the sun will damage it. Therefore, it is necessary to block the light in summer, or move its position to a place without strong light. The lighting conditions at other times should be better, especially in winter

3. Watering: Araucaria lanceolata needs more water during its growing season. Generally speaking, you have to water once every two or three days. However, in winter, it is necessary to reduce the number of watering and keep the substrate dry. It should be noted that no matter which season, no ponding is allowed

4. Fertilization: the demand is not too much. It can be used in the growth period, once or twice a month. Compound fertilizer or calcium fertilizer can be used

2、 Breeding skills

1. Propagation: it can be propagated by sowing. Because the seed coat will have an adverse impact on the germination rate, it is best to remove the seed coat before sowing. Sandy soil is selected as the matrix. Moreover, it is best to disinfect first, because the seedlings propagated in this way are vulnerable to diseases and pests

2. Changing pots: if the seedlings are just planted, it's best to change them once a year and then in spring. If it is an old plant over five years, it can be changed every two or three years. When changing pots, new soil can be prepared with rotten leaf soil, garden soil, vermiculite, etc. For the replacement of seedlings, generally speaking, the flowerpot can also be replaced

3、 Diagnosis and treatment problems

1. Disease: there is "anthrax", which can be treated with carbendazim. There may also be "leaf blight", which can be treated with polysulfide glue, chlorothalonil, etc

2. Insect pests: mainly "scale insects". Generally speaking, Omethoate solution has the best control effect

4、 Other issues

1. Toxicity: it is non-toxic and can purify the air

2. Whether it can be raised at home: Araucaria is also an ornamental plant. It is more appropriate to raise it at home. However, it may take up a large space, and larger flowerpots need to be prepared
