Heat the soil before planting flowers to kill all the insects and bacteria, and no more root rot!

Sun exposure disinfection

If you want to disinfect flowers, the easiest way is to expose them to the sun. Especially for those flowers that are dug from the wild, there are many small insects in the soil, so they must be disinfected before use.

Place the soil in direct sunlight, spread it into a thin layer, and expose it to the sun for more than a week, or seal the soil in a plastic bag and expose it to the sun to kill bacteria and insect eggs.

High temperature disinfection

1. Now it is the transition between winter and spring. The temperature in many places is not very high and the sun is not very strong, so artificial disinfection methods have to be used. Pour the boiling water directly onto the soil until the entire soil is soaked, and pour it several times. Then pour out the excess water and dry the soil to kill the insect eggs and bacteria.

2. If you have an abandoned iron pot at home, it would be even better. Put the soil in an abandoned iron pot, then place it on a gas stove and continuously heat and stir-fry it, using the high temperature to kill the insect eggs and pathogens in the soil. After about half an hour, let the soil dry naturally, and then you can use it directly!

Drug disinfection

It would be even better if you have carbendazim or sulfur powder at home. Put the soil in a foam box, add a layer of soil, and then evenly sprinkle a layer of medicine. Then continue to add soil and medicine, just like making sandwich fertilizer.

After the foam box is filled, seal it with a plastic bag or lid. After about 7-10 days, open the lid or plastic bag, stir it thoroughly to ventilate it, and you can basically use it to grow flowers directly.

Disinfection of buried medicine

In addition to adding some carbendazim to ferment the soil, there is another simple method, which is to buy systemic drugs and bury them in the flower pots. In this way, when watering, the drugs will dissolve with the water, and the insect eggs and bacteria in the soil will be killed.

Spread some wood ash or cigarette ash on the surface of the basin for disinfection

If you find small insects in the potting soil, you can also directly spread a thin layer of collected wood ash, cigarette ash, etc. on the surface of the pot. This will not only prevent the small insects from laying eggs in the soil, but also allow the ash to flow into the flowerpot along with the water when watering, thereby killing the insect eggs and bacteria in the soil.

Okay, that’s all I have to say today.
