Only empty pots left after summer? Don’t throw away the old soil, add some of it and it will instantly become fertile and oily!

How to disinfect the old soil in an empty pot?

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

1. Sun exposure disinfection

Old soil that has been used to grow flowers contains many insect eggs and bacteria that are invisible to the naked eye. It must be disinfected by exposing it to the sun before it can be used. Spread the soil in a thin layer on dry ground and expose it to direct sunlight for 3-5 days.

2. Sterilization with carbendazim or potassium permanganate

If there is not enough space at home to expose to the sun, you can put the old soil in a sealed plastic bucket or plastic bag, add prepared potassium permanganate or carbendazim solution, and then seal it for sterilization and disinfection.

3. High temperature disinfection

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

Add some materials to the disinfected old soil and it will immediately become fertile!

Although it has been disinfected, the nutrients in the old soil that was used to grow flowers have basically been exhausted. If you plant flowers in it again, the flowers in your home will definitely not grow well! Therefore, you must add some ingredients to the soil to make the flowers grow more vigorously!

1. Add some bean dregs to the soil and it will immediately become fertile!

If you want to increase the nutrients in the old soil, you can add some bean dregs fertilizer to it. You can keep the leftover soy milk dregs from your home, or buy some from outside.

Put the old soil in a foam box, add a layer of bean dregs, spread it thinly, then cover it with soil, and then add bean dregs until the entire flower pot is filled, and then seal it for fermentation. It will take about a month to ferment into rich nutritious soil!

2. Add some pine needles to the soil to make it loose and breathable!

The most feared thing when growing flowers is that the soil in the pot is not breathable and causes root rot. So we can take advantage of the autumn to go to the community or the mountains to pick up some pine needles, bring them back and soak them in carbendazim for disinfection.

Mix the sterilized pine needles and old soil together, wrap them in a plastic bag and seal them for fermentation. It only takes about 1-2 months for the pine needles to decompose and turn black, becoming loose and breathable pine needle soil!

3. Add some fruit peels to old soil to grow flowers and make the leaves green!

When you eat fruits at home, don’t throw away the leftover banana peels, watermelon peels, orange peels, etc. Just collect them and compost them in the soil. They are very nutritious!

Chop up banana peels, watermelon peels, etc., mix them with old soil, add some water, seal them and ferment. The fruit ferments very quickly, and it basically only takes one month to be fully decomposed and become nutrient-rich nutritious soil!

Use nutrient soil like this and the plants will grow out of the pot!

After the old soil at home is fermented, you can use it for flowers when you repot them in autumn!

1. When the temperature at home remains at 20-25℃, you can change the pots for the flowers at home! Huahua takes Clivia as an example. First remove the Clivia from the pot and clean the soil on the roots.

2. Prepare the flower pots that need to be repotted, and place a few broken bricks and tiles in the gaps at the bottom of the pots to allow water and air to pass through without leaking soil.

3. Put the fermented nutrient soil into the flowerpot, then carefully place the roots of the Clivia in it, and continue to fill the soil.

4. The nutrient soil that has been fermented in this way can continuously provide nutrients to the flowers, allowing the flowers at home to grow more and more vigorously, with leaves that are green and lush, and they will bloom whenever they want!
