What about the rotten roots of potted lilies?

Last Updated: 2024/12/23, Recently, I heard a friend complain bitterly that he had planted a number of flowers and plants at home, but I don't know why. Two pots of lilies have rotten roots, one pot has died, and the other pot is dying, and it is estimated that it will not be long before it dies. Alas, it's really worrying that we don't know what to do when this happens.
