Don't panic if your lucky bamboo's roots rot - with proper disinfection, its leaves will stay green all year round

To solve the problem of root rot in lucky bamboo, first take the plant out, cut off the rotted parts, and disinfect the plant, then insert it into water or into soil, and place it in a cool, ventilated environment. Don't let it receive strong direct sunlight, and it will grow roots in a few days.
I. Water culture
1. Take the plant out, use disinfected scissors to cut off the rotted roots; for parts where rot cannot be seen with the naked eye, gently press its main stem with your fingers while cutting - any part that has become soft must be cut off. When cutting, cut the roots at a 45-degree angle, then rinse it clean with water, and clean the bottle as well.
2. Pour an appropriate amount of water into the bottle; you can sprinkle a suitable amount of salt into the water to disinfect the plant's roots, then insert the lucky bamboo into the water and place it in a cool, ventilated environment, and it will grow roots in a few days. Don't put it in a place where the temperature is too high or where it can be exposed to strong direct light; just keep its growing environment bright and ventilated.
3. After it has grown roots, add an appropriate amount of compound fertilizer, about one or two drops is enough; if the amount of fertilizer is too large, its roots will rot again. Growing lucky bamboo does not need too much water - one third of the container is enough. If there is too much water, it will very easily cause the roots to rot. You also need to fertilize appropriately; if the usual amount of fertilizer is too large or too frequent, it will cause root rot.
4. If an unusual smell appears in the water, be sure to change the water in time and check whether the lucky bamboo's roots have rotted.
II. Soil culture
1. Take the lucky bamboo out of the potting soil, rinse its roots clean with water, then soak it in carbendazim for a while, rinse it with water, and put it in a cool place to dry.
2. Do not choose too large a flower pot; plant it in loose, breathable potting soil. Hold the lucky bamboo with one hand and bury the soil with the other, then water it thoroughly. Be careful not to use too much soil, otherwise its roots will not be able to absorb water, which will cause root rot again.
3. Lucky bamboo grown in soil is afraid of drought, so water it in time to keep the soil slightly moist.
