Soil sterilization and disinfection

If you want to eradicate insects or eggs in the soil, you should start with the basin soil

1. Exposure disinfection

Before changing the pots and soil for flowers, it is necessary to put the configured nutrient soil on the outdoor clean ground, spread a thin layer and accept the exposure of the sun. Turn over the soil in about 3-5 days, so that the part contacting the ground can also be exposed to the sun. In about half a month, the insect eggs in the soil can be killed

2. Carbendazim disinfection

in order to avoid insect eggs in the soil, some carbendazim can be added to mix when preparing nutrient soil. The ratio of carbendazim to soil is 1:500. After stirring evenly, cover a layer of film on the soil and wait for about 3-5 days. After the taste of carbendazim is completely volatilized, flowers can be planted.   

Sand

After disinfecting the soil and planting flowers, if you are not at ease, you can spread a layer of sand on the surface of the flowerpot to prevent insects

1. Put the prepared clean fine sand in the sun for 3-5 days

2. Lay a thin layer of dry sand on the surface of the flowerpot. In this way, after watering, mosquitoes can't drill into the soil to lay eggs
