Soil disinfection method

1. First of all, the replaced old soil must be exposed to the sun for a few days. If there are residual roots of a pot of flowers or wild grass roots in the soil, they should be picked up and thrown away

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

3. The soil can be sprayed with some insecticides for raising flowers to remove the insect eggs in the soil

4. You can also scald it with boiling water. The scalding water can kill bacteria, small insects and so on in the old soil

5. If the amount of old soil is not very large, it can be put into a container and heated in a microwave oven for 3 ~ 5 minutes. This method is convenient and fast, and the effect is also very good

6. You can also put the dried soil into a plastic bag and seal and fasten the bag mouth tightly for a few days. Most insects and eggs suffocate in an oxygen deficient environment

Nourish it, nourish it

After sterilization, the old soil has been relatively clean, but there is little nutrition, and has hardened and poor air permeability. You can add something to Rett the soil and make the soil fertile

1. There are many things that can be used to Rett soil, such as soaked soybeans, coffee grounds, rotten vegetable leaves and so on

2. The leftover fruit peel can also be used to Rett soil. If there is a small courtyard or open balcony at home, it can also Rett nutritious soil with strong taste such as fish intestines and chicken manure

3. First 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 mouth of the flowerpot with plastic film or plastic bag. It's best not to leave gaps

5. Retting takes a long time. It takes about 2 ~ 3 months in warm days and about 4 months in winter

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

7. If the freshly retted soil has a large moisture content, it can be dried in the sun and reused, so that the soil will be more breathable

8. Finally, Huahua should remind everyone that if the old soil once raised sick flowers, they can no longer be used. Otherwise, if there are residual bacteria, the next pot of flowers will be infected

That's the way to change old soil into new soil

If you have replaced the old soil, you might as well try it
