The old soil after growing flowers is treated in this way. Continue to grow flowers and let flowers rub against each other.

The little thing of growing flowers has become a trend. People who grow flowers should know that spring is the best time for plants to change pots. There are many flower friends who will change the soil and use it directly without treatment. Some flower friends throw away the changed soil directly, and many people do not know how to use the old soil. Then I will introduce to you how to deal with the old soil.

As mentioned above, does it feel very wasteful to throw away the old soil directly? In addition, it is also wrong to use the old soil directly without treatment, because there may be some eggs or germs in the newly changed soil, and plants may be infected if they grow flowers directly. What are we going to do? in fact, as long as we simply dispose of the old soil, we can turn the old soil into new soil.

First of all, it is necessary to disinfect the old soil, which can be baked in the microwave oven for disinfection, but this method is rarely used. The most commonly used method is to put the old soil into a black plastic bag, and then put it under the sun for exposure, which can be used for about half a month.

While the old soil is sterilized, nutrients are also losing, so after the old soil is sterilized, some organic fertilizer can be added to the old soil, and then some new soil can be mixed evenly, so that the soil can have sufficient nutrients and plants can grow better.

Of course, many flower friends say that this is too troublesome, it is better to directly use drugs to sterilize, in fact, as long as pay attention to the methods of drug use, do not hurt plants, it is also possible.
