Brazil iron pillar, formerly known as Dracaena, is basically imported from abroad. In tropical areas, it can be as high as 56 meters in the open field. The trunk is seven to fifteen centimeters in diameter. Its bark is yellow and wrinkled. Both leaves and stems can be observed. When planting into the pot, the tree stems are generally sawn into three sections: high (about 1.5 m), medium (about 1 m) and low (about 0.5 m) to form a group of species in one pot. The sitting room is really vigorous, vigorous and full of vitality, which is of great ornamental value.

1. Malnutrition

Most of the incisions of Brazilian iron trunk can germinate two or three new buds. But because the basin soil bought is mostly coarse sand, the nutrient supply is insufficient, the iron pillar lacks nutrition, and the indoor air is dry, the leaves will gradually wither and yellow. At this time, spray it two or three times a day, once a week with one thousandth of ammonium sulfate and potassium dihydrogen phosphate solution. When the weather is warm, use a big pot, change the new soil, and plant again. In the future, you can plant more white roots and continue to grow vigorously.

However, it is not suitable to make basin soil ponding to prevent root rot caused by poor ventilation. After the end of autumn, the amount of watering should be controlled to keep the basin soil slightly wet.

3. Cultivation management

The three seasons of spring, summer and autumn are the vigorous growth season of Brazilian iron. During this period, the cultivator must fully meet its water, nutrient, temperature and needs to make it grow healthily.
