Treat old soil this way and keep using it for growing flowers to make them thrive

Growing flowers has become a trend, and people who grow flowers should all know that spring is exactly the best time to repot plants. Many flower-loving friends take the soil that has been swapped out and use it directly without treating it, while other flower lovers simply throw the swapped-out soil away. Many people do not know how to use old soil properly, so below I will explain how to treat old soil.

As mentioned above, doesn't it feel very wasteful to just throw old soil away? Also, using old soil directly without treating it is not right either, because the soil just swapped out may contain some insect eggs or pathogens, and if used directly for growing flowers it may cause the plants to become infected. So what should be done? Actually, you just need to treat the old soil simply, and you can turn old soil into new soil.

First, the old soil must be disinfected. You can put the old soil in a microwave and heat it to disinfect it, though very few people use this method. The most commonly used method is to put the old soil into a black plastic bag and then place it under the sun to bake, and after about half a month of sun exposure it can be used.

While the old soil is being sterilized, nutrients are also being lost, so after the old soil has been disinfected, you can add some organic fertilizer to it, then add some new soil and mix it evenly. This way the soil will have sufficient nutrients and the plants will grow better.

Of course, many flower lovers say this is too troublesome and that it would be better to just use chemicals to sterilize. Actually, as long as you pay attention to how the chemicals are used and do not harm the plants, that is also fine.
