What causes potting soil to clump? Here's how to handle it correctly

We need to know what causes soil to clump. Generally speaking, it is caused by pouring water into water or irrigating with a large amount of water.
Tap water contains fluorine and chlorine compounds and is hard water. Pouring it directly onto the soil over the long term easily causes the soil to harden. It is best to water with rainwater or water after a few days, especially in the northern soil.
Another thing that makes soil harden is soil that is made fertile; it usually easily causes soil to clump, such as unrotted tea leaf residue, coffee grounds and rice water, which are not directly absorbed by the soil but can ferment in the soil.
Other causes of soil hardening include root growth and soil moisture.
Fertilizer can cause soil to clump, but adding some rotted organic fertilizer to the soil can alleviate the clumping, and can also increase soil fertility and improve soil structure.
Crush the organic fertilizer directly into powder, remove the soil on the surface of the pot, then mix the organic fertilizer powder into the potting soil and replace the surface soil.
Then wait for the soil to dry completely and let the fertilizer slowly seep in, thereby replenishing soil fertility and promoting plant growth.
When caring for potted plants, do not put raw fertilizers directly into the soil; various tea leaves, milk, fruit peels, rice water, etc., should not be put directly into the potting soil. After fermenting in a container or plastic jar, they can be used as fertilizer.
Potted plants that grow quickly can be repotted once every 1 to 2 years; if they grow slowly, they can be repotted once every 2 to 3 years, so poor plant growth caused by soil clumping can be avoided.
Now that the problem of hardened soil is solved, let me introduce vinegar to you, but it is a good helper for flowers. If the soil is alkaline, plants will develop yellow leaves, fail to bloom, and even wilt. This is especially true for some plants, such as those that need slightly acidic soil; alkaline soil is like this. It is not good for plant growth.
At this point, you can directly buy ferrous sulfate for your flowers. Of course, you can also add vinegar to the water for your flowers. The ratio is 1:20 to 100.
