A complete guide to the cultivation methods and precautions of Araucaria

1. Maintenance methods

1. Temperature: Araucaria prefers slightly higher temperatures, between 25 and 30 degrees, which is most suitable. However, too hot a season is not conducive to its growth. Therefore, when the temperature is above thirty-five, try to adjust it. In addition, it is a very cold-resistant plant and basically does not require any adjustment in winter.

2. Light: Araucaria is a light-loving species, but it needs to be shielded from too strong light, as excessive exposure to the sun will damage it. Therefore, it needs to be shaded in summer or moved to a place without strong light. Try to keep the lighting conditions better at other times, especially in winter.

3. Watering: Araucaria requires more water during the growing season. Generally speaking, you need to water the plants every two or three days. However, in winter, you need to reduce the frequency of watering and keep the substrate drier. It should be noted that water should not accumulate regardless of the season.

4. Fertilization: The demand is not too much. It can be applied during the growth period, once or twice a month. You can use compound fertilizer or calcium fertilizer.

2. Breeding techniques

1. Reproduction: It can be propagated by sowing. Since the seed coat will have an adverse effect on the germination rate, it is best to remove the seed coat before sowing. Sandy soil was used as the substrate. Moreover, it is best to disinfect them first, because seedlings propagated in this way are susceptible to diseases and pests.

2. Repotting: If it is a newly planted seedling, it is best to repot it once a year in the spring. If it is an old plant over five years old, it can be replaced every two or three years. When repotting, you can prepare new soil using leaf mold, garden soil, vermiculite, etc. When repotting seedlings, the flower pots can generally be replaced as well.

3. Problem diagnosis and treatment

1. Disease: If "anthracnose" occurs, it can be treated with carbendazim. There may also be "leaf blight", which can be treated with polysulfide glue or chlorothalonil.

2. Pests: Mainly scale insects. Generally speaking, omethoate solution is the most effective in their prevention and control.

IV. Other issues

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

2. Can it be grown at home? Araucaria is also an ornamental plant and it is more appropriate to grow it at home. However, it may take up more space and require a larger flower pot.
