2. Hypoxia: If the water is not changed for a long time, the oxygen in the water will be gradually consumed, and the roots of the green radish will easily rot due to hypoxia.
3, too much water: when changing water, it is too full, soaking the whole plant in water, causing the roots to be unable to breathe, leading to root ulceration.
4. Temperature: If the temperature is too high, it will easily lead to the rapid aging of plant roots, which will lead to decay. If the temperature is too low, plants will get frostbite, including the roots. After frostbite, the roots can no longer breathe, thus aging and rotting.
5, nutrient solution: too much nutrient solution or low dissolved oxygen content in water, leading to plant hypoxia.
6, bacterial infection: in a hot and humid environment, bacterial fungi are easy to breed, and the roots of green radish are easy to infect and rot.
Second, how to remedy rotten roots 1. When rotten roots appear, cut off the rotten parts of the roots with scissors to avoid hurting other healthy roots.
2. Pour out the original water and replace it with clean water, preferably pure water instead of tap water. There are too many microorganisms in tap water, which will consume nutrients in the water and cause secondary damage to radish.
Be careful not to soak all the green radish in the water when changing the water. It is best that the water surface only passes through the highest point of the plant roots, so as not to hinder the breathing of the plant roots.
4. Go to the flower market to buy fungicides, put them in water, soak the plants for one day, and change them to new water the next day.
5. Adjust the indoor temperature to adapt to the survival of plants.
6. Only water is needed for root rot, and no nutrient solution is used.
