Can the soil that has been planted still be used?
An explanation for netizens on whether the soil that has been planted can still be used, and a technique to instantly turn old soil into fertile soil in the field of green plants and flowers, the following is an introduction by the editor for netizens.
How to disinfect the old soil in empty pots?
The old soil used for growing flowers can be used, but it must be sterilized and disinfected before use, otherwise the bacteria in the soil will infect the newly potted flowers. So, how to disinfect old soil?
1. Sunlight disinfection
The old soil used for growing flowers contains many eggs or invisible bacteria, which must be disinfected by sunlight before use. Spread the soil thinly on a dry ground surface and expose it directly to the sun for 3-5 days.
2. Multi-jinling or potassium permanganate disinfection
If there isn't enough space to expose to the sun, you can put the old soil in a sealed plastic bucket or plastic bag, add a solution of potassium permanganate or multi-jinling, and then seal it for sterilization and disinfection.
3. High-temperature disinfection
Finally, I will introduce a simple method of high-temperature disinfection. Find an unused iron pot at home, stir-fry the soil in it, or place it in a microwave oven and heat it for more than 5 minutes, which can basically achieve the purpose of sterilization and disinfection.
After disinfection, add some ingredients to the old soil, and it will immediately become rich in nutrients!
Although it has been disinfected, the old soil used to grow flowers has basically exhausted its nutrients. If you plant flowers directly, they will definitely not grow well at home! Therefore, you must add some ingredients to the soil to make the flowers grow stronger!
1. Adding some soybean dregs to the soil will make it rich in nutrients!
If you want to increase the nutrients in the old soil, you can add some soybean dregs. You can save the dregs left from making soy milk at home, or collect some from outside.
Put the old soil in a Styrofoam box, add a layer of soybean dregs, spread them thinly, then cover with soil, add more dregs, and continue until the entire pot is filled, then seal it for fermentation. In about 1 month, you can make rich and nutritious soil!
2. Adding some pine needles to the soil will make it loose and breathable!
The worst thing about growing flowers is that the soil in the pot is not breathable, leading to root rot. So we can take advantage of autumn to collect some pine needles from the community or the mountains and disinfect them with multi-jinling.
Mix the disinfected pine needles with the old soil, wrap them in a plastic bag and seal them for fermentation. It will only take about 1-2 months for the pine needles to decompose into black, loose, and breathable pine needle soil!
3. Adding some fruit peels to the old soil will make the leaves green and shiny!
When eating fruit at home, don't throw away the remaining banana peels, watermelon peels, or orange peels. Collect them to make soil, which is also rich in nutrients!
Chop up all the banana peels, watermelon peels, etc., mix them with the old soil, add some water, and seal them for fermentation. Fruit fermentation is quick, usually taking only 1 month to decompose into nutrient-rich soil!
Using the nutritious soil in this way will make the plants grow rapidly and burst into bloom!
After the old soil at home has been composted, it can be used for the plants during the pot-changing season in autumn!
1. When the temperature at home is consistently between 20-25°C, you can repot the flowers. Taking orchids as an example, first remove the orchid from the pot and clean the soil off the roots.
2. Prepare the pot for repotting, placing a few pieces of broken brick or tile in the bottom holes to achieve the purpose of water permeability, breathability, and no soil leakage.
3. Fill the pot with the composted nutritious soil, carefully place the orchid roots in it, and continue to fill the soil.
4. The well-composted nutritious soil can continuously provide nutrients for the flowers, making the flowers at home grow stronger, leaves green and shiny, and bloom whenever they want!
The above is a comprehensive explanation of whether the soil that has been planted can still be used and the technique to instantly turn old soil into fertile soil, hoping it can help you.
