How to disinfect the soil

The role of soil in flowers

Soil can stabilize plants; provide sufficient powder and nutrients so that flower plants can thrive; and supply air so that the roots of shrubs can breathe. In general, the soil used for growing flowers must be loose and fertile, well-drained, highly water-retaining and air-permeable. For flowers grown in the open field, as long as you choose a good sandy loam area, you can meet the growth conditions of the flowers.

Sunlight Disinfection

Spread a thin layer of soil on the clean cement floor or wooden board for the potted flowers, expose them to the sun for 2 to 3 days, and turn them over several times.

Drug disinfection

Commonly used agents include formalin, potassium permanganate, ferrous sulfate, and thiophanate. Potassium permanganate and formalin are usually used at a concentration of 0.5%, ferrous sulfate at 1%~2%, and thiophanate at 0.3%. The disinfected soil should be dry, spread out into a 20 cm thick layer, and then spray the solution on it and cover it with a film. Uncover the cover after 2 days, turn it over and dry it in the sun for 1 week. It can be used only after the smell of the medicine has dissipated.
