Buried charcoal picked from a trash can in the clivia flower pot, it burst into explosive growth

Trash cans don't just yield cardboard; you can also find great things for growing flowers. Sure enough, one day I picked up a piece of charcoal, took it home and put it in a flower pot, and the clivia didn't get root rot and grew vigorously.

Charcoal itself is fairly loose, which makes it excellent for retaining water, and because it has been burned at high temperatures, there's no need to worry about pathogens. On top of that, charcoal is black, and black has a very strong heat-absorbing capacity. Overall, its insulation and water-retention effects are both good, making it a great material for growing flowers.

The minerals charcoal itself is rich in can also help plants grow. It can be placed at the bottom of a flower pot or mixed into the soil, effectively preventing root rot, and it can also be scattered on the surface of the potting soil, where it has a certain disinfecting and sterilizing effect, especially for fleshy-rooted flowers like clivia.

The method of use is also simple:

The piece of charcoal you pick up can't be used as a whole block; you have to break it up first;

Slightly larger pieces of charcoal can be used to line the bottom of the flower pot, allowing water and air to pass through and making root rot unlikely; slightly smaller pieces of charcoal can be mixed into the clivia's soil and used as granular soil, so the potting soil is also airy;

Very fine charcoal powder can be scattered on the surface of the clivia's potting soil, making it loose and airy, keeping the soil from looking especially dry, and also reducing pests.
