Old potting soil is better for growing flowers than new soil, and you won't need to fertilize the flowers for two years

Although old potting soil can still be used, after all, it has already been used to grow flowers before, and all the nutrients in it have been absorbed. If you use it directly to grow flowers, it may cause the plants to grow weakly, and it also contains some pathogens and insect eggs. So if we want to use old soil to grow flowers, we must take some measures

We need to choose weather with scorching sun, then take the old soil out of the flower pots and spread it flat on the ground, and expose it to the sun for two or three days before it can be used, because this serves to kill pathogens and insect eggs. When we spread it flat, we must make it even to ensure every lump of soil can be exposed to the sun

The nutrients in the original old soil may be insufficient, so we can add some new nutrient-rich soil. We mix the sun-dried old soil with new leaf mold or granular soil. The ratio is two parts old soil, one part leaf mold, and one part granular soil. This way it can be used, and the effect is very good

Then we use the prepared old soil to plant plants like Chinese rose or clivia, plants that need less fertility. In this way, the old soil also achieves the effect of reusing waste and can also make full use of resources. Isn't it killing two birds with one stone? Go and try it
