Can iron leaves be resurrected from the dead after their roots are rotten?

The bare-root iron tree purchased has withered leaves and rotten roots after 2 months of planting, which is mainly caused by the following reasons.

First, because the iron tree naked root, from the south to the north, without the necessary wind and cold protection measures, because its root system is seriously damaged and can no longer provide water for the plant, usually the leaves turn brown and then die.

Second, because the root system is blown by the wind or frozen later, it is bent repeatedly during transportation, which will inevitably cause it to lose its function of absorbing water and nutrients. If it is planted in a pot, it does not cut off some leaves in time and does not cut off the lifeless root system. It may be planted with fertile humus culture soil, coupled with too much watering, or even fertilizing before its absorption function is restored. In this way, due to the poor permeability of basin soil and the enrichment of water and nutrients, the root system will inevitably rot.

For the iron tree with withered leaves and rotten roots, can it be "dead" and resurrected? In fact, this kind of death is a "fake death", and its vitality is extremely strong, as long as its stem is not soft by freezing or water seepage and rot, it can be revived by exercising special rescue measures to make it "dead". The specific methods are as follows: first, the leaves of the plant are cut off from the base, and then the rotten roots are trimmed clean, and the root scissors can be treated with sulfur powder and clean charcoal powder for anticorrosion treatment, then put them in a warm and ventilated place to dry, re-select clean flowerpots, plant roots with moist and clean river sand, and the water content of sand should be clustered and loosened by hand. Be careful not to bury all the stems of the iron tree in the sand, only 3 to 5 centimeters above the root neck.

Put it in a warm room to keep the sand moist and let it survive the winter safely. After Grain Rain next spring, he moved it outside and buckled it on the plant with a tile basin without a drain hole, creating a dark environment to induce new leaves. As long as the stem is not rotten, the root system can sprout again and new leaves can be produced at the same time from May to June. When the iron tree leaves about 10 cm long, should uncover the buckle basin, put it in a better light position, but at this time must not be exposed to the sun, so as not to burn the tender leaves. At the same time, pay attention to the control of moisture, so that the leaves will not be too thin and too long. After the leaf growth is stable, it can be re-cultivated in fertile soil and given normal water and fertilizer management.
