Spring is getting thicker and the weather is getting warmer and warmer, which is the growing season of plants, so many flower friends and babies will choose to change the soil for plants, but don't throw away the soil, add something, and make sure you can use it again. In this way, it is worthwhile to have money left to buy nutritious soil.

Disinfection of old soil

First of all, put the changed soil under the sun for a few days, and pick up the residual roots in the soil. Then turn over the soil with a small shovel to see if there are any worms. If so, you must take them out. You can also spray some pesticides to kill the invisible eggs.

Retting soil

Above we have sterilized soil, after the absorption of plants, there is no nutrition, and the air permeability is very poor, so we can add some coffee grounds, vegetable leaves, peel and so on to retting the soil to make sure that the soil becomes full of fertility. let the plants flourish.

First, spread a layer of old soil under the container, then spread some fertilizer to compost the soil, and then lay a layer of soil, so repeat the action. After filling the container, pour the right amount of water into the soil, it is best to seal it, put it under sufficient light, basically about 3 months, after opening the container to see that the soil has blackened, you can use the soil to grow flowers!

If the potted plant has already been sick, then do not use the old soil, so that if you disinfect the unclean and residual bacteria, it will directly infect the new plant.
