1、 Proper shade

Although Araucaria lanceolata likes light, if it is exposed to strong light, its leaves will also be sunburned, affecting photosynthesis and causing it to fall off. Usually in summer, you need to do a good job of shading, or put it in a bright place indoors to let it receive scattered light. However, if in winter, it is necessary to ensure sufficient light, which is conducive to raising the temperature and allowing it to survive the winter safely

2、 Replenish water

Araucaria lanceolata is suitable to grow in a humid environment, and its drought tolerance is relatively poor. Therefore, watering must be frequent to avoid leaf loss due to dry environment. During the growth period of the plant, water it twice or three times a week to ensure that the soil is moist. If the temperature is relatively high and the water evaporates quickly, it is necessary to spray water around to alleviate the water loss caused by transpiration

3、 Keep warm in winter

Araucaria lanceolata is afraid of cold. It needs to do a good job of cold prevention and warmth preservation in winter. If the temperature is relatively low, the leaves will fall off after being frozen. Usually, before winter, the plants need to be moved to a warm place indoors to ensure that the temperature is not lower than 8 ℃. 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

4、 Rational fertilization

The growth of Araucaria requires certain nutrients, so it needs to be fertilized. When planting, an appropriate amount of rotten organic fertilizer should be added as the base fertilizer. After spring, fertilizer should be applied regularly, usually 1-2 times a month. The fertilizer should use thin liquid fertilizer and supplement calcium fertilizer at the same time, so as to make the color of leaves more oily
