Don't throw away old soil after summer ends; mix in a little of this and it instantly becomes fertile.

How do you disinfect old soil from empty pots?

Old soil that has been used to grow flowers can be used, but it must be sterilized and disinfected before use, otherwise the bacteria in the soil will infect newly potted flowers. So, how do you disinfect old soil?

1. Sun exposure disinfection

Old soil that has been used to grow flowers contains many insect eggs or bacteria invisible to the naked eye, and must be disinfected by sun exposure before use. Spread the soil in a thin layer on dry ground and expose it directly to the sun for 3-5 days.

2. Carbendazim or potassium permanganate sterilization and disinfection

If your home does not have enough space for sun exposure, you can put the old soil in a sealed plastic bucket or plastic bag, add a prepared potassium permanganate or carbendazim solution, and then seal it to sterilize and disinfect.

3. High-temperature disinfection

Finally, Huahua will introduce a simple method to everyone, which is high-temperature disinfection. Find an unused iron wok at home, put the soil in it and stir-fry it a few times, or put it in the microwave and heat it directly for more than 5 minutes, and basically the purpose of sterilization and disinfection can be achieved!

Mix a little something into the disinfected old soil, and it instantly becomes so fertile it drips oil!

Although it has already been disinfected, the old soil that was previously used to grow flowers has basically had its nutrients exhausted. If you directly use it to grow flowers again, the flowers at home will definitely not grow well! So you must mix a little something into the soil to make the flowers grow more vigorously!

1. Mix a little okara into the soil, and it instantly becomes so fertile it drips oil!

If you want to add nutrients to old soil, you can add a little okara fertilizer to it. Usually, keep the okara left over from making soy milk at home, or go out and ask for some.

Put the old soil in a foam box, add a layer of okara, spread it thinly, then cover it with soil, add more okara, until the entire flower pot is filled, and then seal it for fermentation. In about 1 month, it can be composted into rich nutrient soil!

2. Mix a little pine needle into the soil, loose and breathable!

The thing most feared when growing flowers is poor air permeability in the potting soil causing root rot. So we can take advantage of autumn to pick up some pine needles in the neighborhood or on the mountain, bring them back, and soak them in carbendazim for disinfection.

Mix the disinfected pine needles with the old soil, wrap it in a plastic bag and seal it for fermentation. It takes only about 1-2 months, and the pine needles will decompose into black material and become loose, breathable pine needle soil!

3. Add a little fruit peel to old soil, and the leaves of the flowers you grow will be glossy green!

When eating fruit at home normally, do not throw away the leftover banana peels, watermelon rinds, orange peels and so on. Just collect them directly to compost soil, and the nutrients are also very abundant!

Chop up banana peels, watermelon rinds and so on, then mix them with the old soil, add a little water, and seal it for fermentation. Fruit ferments very quickly, and basically it takes only 1 month to decompose well and become nutrient soil full of nutrients!

Use nutrient soil like this, and the plants will grow rapidly and fill the pot!

After the old soil at home has been composted, it is just right to use it for the flowers when repotting in autumn!

1. When the temperature at home stays at 20-25°C, you can repot the flowers at home! Huahua will take the clivia as an example. First take the clivia out of the pot and clean off the soil on the roots.

2. Prepare the flower pot needed for repotting, and place a few pieces of broken brick or tile over the hole at the bottom of the pot, so as to achieve water permeability and air permeability without leaking soil.

3. Put the composted nutrient soil into the flower pot, then carefully place the clivia roots in, and continue filling with soil.

4. The nutrient soil composted in this way can continuously provide nutrients to the flowers, making the flowers at home grow more and more vigorously, with leaves so green they drip oil, and they will bloom whenever they want!
