Although Araucaria likes light, if it is exposed to strong light, it will also cause sunburn, affect photosynthesis and cause it to fall off.Usually in summer, it needs to do a good job of shading, or put it in a bright place indoors, so that it can receive scattered light.However, if in winter, it is necessary to ensure adequate light, which is conducive to raising the temperature, so that it can survive the winter safely.
Araucaria is suitable for growth in a humid environment, and its drought tolerance is relatively poor, so watering must be frequent, so as not to cause leaf loss due to dry environment.During the growing season, water the plant two to three times a week to make sure the soil is moist.If the temperature is relatively high and the water evaporation is fast, it is necessary to spray water around properly to alleviate the water loss caused by transpiration.
Araucaria is more afraid of cold, winter needs to do a good job of cold and warm work, if the temperature is relatively low, the leaves will fall off after freezing.Usually before winter, plants need to be moved indoors to warm places to ensure that the temperature is not lower than 8 degrees Celsius.If the room temperature is low, you can use a larger plastic bag to completely cover the upper part of the plant, which is also a good heat preservation.
The growth of Araucaria requires a certain amount of nutrients, so it needs to be fertilized.When planting, appropriate amount of decomposed organic fertilizer should be added as base fertilizer, and regular topdressing should be applied after spring, usually 1-2 times a month, thin liquid fertilizer should be used as fertilizer, and calcium fertilizer should be supplemented at the same time, so that the color of leaves can be more oily.
