1、 How

1. Soil: when cultivating iron trees, the soil with good air permeability should be used. The soil with high viscosity and air tightness will hinder the growth of roots. The drainage performance of cultivated soil should also be stronger, because it is afraid of ponding. Too much water will cause rotten roots

2. Light: in the process of maintenance, good light should be ensured. It likes sunshine and will grow better in an environment with sufficient light. However, the seedling stage needs appropriate shade and cannot be directly exposed to the sun. In addition, it is good to have strong light in summer. It should be shielded from light and cannot be exposed to the sun

3. Moisture: it has good drought resistance, as long as it is not watered for a long time. Watering is generally dry and wet. The most scientific method is to water according to the soil. If the water is fixed, it may accumulate water due to weather and drainage, which is not conducive to the growth of its roots

4. Nutrient: in the process of fertilization, thin fertilizer should be applied frequently. Fertilizer with low concentration should not be applied, and raw fertilizer should not be applied to it. Fertilization is mainly nitrogen fertilizer and potassium fertilizer, and some fully decomposed cake fertilizer and water can be applied

2、 Precautions

If it is potted maintenance, you should pay attention to changing the pot. Usually, the pot soil should be changed once in 2-3 years. During normal maintenance, the soil shall be properly turned over to maintain a good air permeability of the soil
