How to disinfect the old soil in the empty basin

The old soil with flowers can be used, but it can only be used after sterilization, otherwise the bacteria in the soil will infect the new flowers. So, how to disinfect the old soil

1. Sun exposure disinfection

The old soil with flowers contains many insect eggs or bacteria invisible to the naked eye. It can only be used after being exposed to the sun and disinfected. Spread a thin layer of soil on the dry ground and directly expose to the sun for 3-5 days

2. Carbendazim or potassium permanganate sterilization

If you don't have such a big place to expose to the sun at home, you can put the old soil in a sealed plastic bucket or plastic bag, add the mixed potassium permanganate or carbendazim solution, and then seal it for sterilization and disinfection

3. High temperature disinfection

Huahua finally introduces a simple method to you, that is, high-temperature disinfection. Find an unused iron pot from home, stir fry the soil in it for a few times, or put it in the microwave oven and heat it directly for more than 5 minutes. Basically, the purpose of sterilization and disinfection can be achieved

After disinfection, the old soil is mixed with some materials, which makes it fat and oily immediately

Although it has been disinfected, the old soil that has raised flowers before has basically run out of nutrients. If you plant flowers directly, the flowers in the family will certainly not grow well! Therefore, we must mix some materials in the soil to make the flowers grow more prosperous

1. Add some bean dregs into the soil and it will be fat and oily immediately

If you want to add nutrients to the old soil, you can add some soybean residue fertilizer to it. Usually, you can leave the leftover dregs of soybean milk at home or go outside to order

put the old soil in the foam box, add a layer of bean dregs, spread it in a thin area, then cover the soil, then add bean dregs until the whole pot is filled, then sealed up and fermented. It can be retted into thick nutrient soil in about a month

2. Soil mixed with pine needles, loose and breathable

The fear of flower cultivation is that the pot soil is airtight, resulting in rotten roots. So we can take advantage of the autumn to pick up pine needles in the community or on the mountain, take them back and soak them in carbendazim for disinfection

Mix the sterilized pine needles with the old soil, wrap them in plastic bags, seal and ferment. It only takes about 1-2 months, and the pine needles can rot into black and become loose and breathable pine needle soil

3. Add some fruit peel to the old soil and keep the flowers and leaves green

When eating fruit at home, don't throw away the rest of banana peel, watermelon peel and orange peel. Collect them directly to Rett the soil, and the nutrition is also very sufficient

Chop all the banana peel and watermelon peel, mix them with the old soil, add some water and seal them for fermentation. The fruit ferments very fast. Basically, it only takes one month to mature and become a nutrient soil with sufficient nutrients

The nutrient soil is used like this. Rub the long explosion basin

After the old soil at home is retted, it can be used for flowers when changing pots in autumn

1. When the temperature at home continues to be 20-25 ℃, you can change the pots of flowers at home! Take Clivia as an example. First remove the Clivia from the basin and clean the soil on the root system

2. Prepare the flowerpot that needs to be replaced, and pad several broken bricks and tiles at the pores of the basin bottom to achieve the purpose of water permeability and no soil leakage

3. Put the retted nutrient soil into the flower pot, carefully put the root system of Clivia into it, and then continue to fill the soil

4. In this way, the retted nutrient soil can continuously provide nutrients to the flowers, so that the longer and more prosperous the flowers at home, the green leaves drop oil, and bloom if you want to bloom
