1. Take the plant out of the pot soil and soak the whole plant in water for one day.

2. Take it out and mud the roots (remove the dry roots in advance).

3. Plant it in a pot again, pour enough water and cover the plant with a wet cloth.

Put the basin in the shade and spray water on the cloth every day to prevent it from drying, but don't water the basin soil. In this way, plants will sprout new buds in about half a month. See the sun gradually, but don't expose yourself to the sun.
