1. Soil: Araucaria is suitable for growing in fertile soil. If it is too poor, the plant will grow poorly due to insufficient nutrients. Therefore, it is necessary to ensure that the soil has certain fertility, or add a proper amount of organic fertilizer as base fertilizer.If you want to prepare potting soil, you can use loam, rotten leaf soil and coarse sand mixed, the ratio of the three is 3:1:1, such soil is very helpful for the growth and development of plants.
2. Light: Araucaria is a kind of light-loving plant, but it is not resistant to strong light. In summer, the hot sun can easily sunburn the leaves of the plant, affecting its development.Usually put it in a semi-shady environment, or give it appropriate shade, but in winter need to ensure adequate light, so as to properly raise the ambient temperature, for the safe winter is also helpful.
3. Watering: The drought tolerance of araucaria is relatively poor, and the demand for water is relatively high, so it must be watered frequently.During the growing season, it is usually watered 2-3 times a week, and the water should penetrate into the soil to a depth of 10-15 centimeters.Watering can be reduced as it grows, but keep the soil moist.In high temperature season, it is necessary to spray water properly to increase environmental humidity.
4. Fertilization: Araucaria needs sufficient nutrients to help it grow.In addition to applying enough base fertilizer when planting, it should also be properly topdressed in its growth period.From the beginning of sprouting, 1-2 times of decomposed thin liquid fertilizer should be applied every month, the concentration of fertilizer must be paid attention to, if applied with thick fertilizer, it is easy to damage its root system, leading to its decay.
Indoor cultivation of araucaria requires good control of its height. Usually, when it grows to a height of one or two meters, the top bud needs to be cut off, so that the plant will not continue to grow tall, and it can also promote the development of lateral branches.
