Don't throw away the old soil after changing the basin. Add this one. It's more fertile than nutritious soil!

Soil disinfection method

1. First of all, the old soil must be exposed to the sun for several days. If there is a residual root system of a potted flower or a wild grass root in the soil, it must be picked up and thrown away.

2. Turn over the soil with a small shovel. If there are pests such as centipedes and snails, you can catch them and kill them to prevent the next pot of flowers from being harmed.

3. Spray some flower growing insecticides in the soil to get rid of the eggs in the soil.

4. It can also be scalded with boiling water. The scalding water can kill bacteria and insects in the old soil.

5. If the amount of used soil is not large, it can be put into a container and heated in a microwave oven for 3-5 minutes. This method is convenient, quick and effective.

6. The dried soil can also be put into a plastic bag and sealed tightly for several days. Most insects and eggs will suffocate and die in anoxic environment.

Add some old soil to it, better than nutritious soil!

After sterilization and disinfection, the old soil has been relatively clean, but there is almost no nutrition, and it has been hardened, with poor permeability. Can add a few things to undertake retting soil, let soil become fertile!

1. There are many things that can be used to retouch soil, such as soaked soybeans, coffee grounds, rotten cabbage leaves, etc.

2. You can also retouch the remaining fruit skins. If you have a small yard or open balcony at home, you can also retouch fish intestines, chicken manure and other nutritious soil with great taste.

3. Lay a layer of old soil under the flowerpot, then lay a layer of prepared retting material, and then lay the soil. Repeat the operation until the flowerpot is full. Then pour some water into the soil.

4. Seal the flower pot mouth with plastic film or plastic bag. It's better not to leave any space.

5. It takes a long time to retouch the soil. If it is warm, it will take about 2-3 months. In winter, it will take about 4 months.

6. When taking off the bag, if the color of the soil has turned black, it will be rotten.

7. If the water content of the soil just retouched is relatively large, it can be put in the sun and used again, so that the soil will be more breathable.

8. Finally, Huahua should remind you that if the old soil has ever raised sick flowers, they can no longer be used, or if there is residual bacteria, the next pot of flowers will be infected!
