People who spend a long time planting flowers often encounter potted worms. I briefly introduce several methods:
First, the prevention method. Before putting the potted flowers into the pot, put the pot soil into a large old food bag, pour boiling water, tie the mouth of the bag tightly, expose it to the sun for a day, and then spread it out to dry, which can kill the eggs.
Second, chemical methods. Long-term moisture in the basin soil causes pests, so you can buy pesticides, spray pesticides and avoid using indoor potted plants.
Third, change the living environment of pests, move flowerpots to dry and ventilated places, bask in the sun, pay attention to watering in time, and cover shade-loving flowers, such as orchids and asparagus, to prevent sunburn.
Fourth, replace the basin soil. Use suitable potted soil disinfected by insects and bacteria to completely change the soil. After changing soil, attention should be paid to shading and curing for a period of time before it can be transferred to normal planting.
Summary: It is a common phenomenon that insects grow in the soil where flowers are planted, and there are many reasons. The main reason is that the soil is not well treated, and many germs, eggs and pests live or overwinter in the soil. So the best way is to change the basin, that is, change the soil. If you haven't started cooking, kill the soil before cooking.
