First, the causes of potted flower soil hardening
1, poor irrigation
When watering, if the water quality is not suitable, in fact, it is easy to have soil problems, such as soil hardening, which generally means that there are many elements such as calcium and magnesium in the water when watering, which are not very soluble in water, and soil hardening is easy to occur when watering.
2. Improper fertilization
If the soil itself contains more calcium, then the use of ammonium sulfate in fertilization will easily lead to soil hardening. There is also the heat of watering with unfermented milk, which is also unfavorable to the growth of plants.
Second, how to prevent soil hardening
1, select soil
To prevent soil from hardening, it is very important to choose soil, and to ensure that the soil is loose, breathable, free from water accumulation and moist. You can choose sand, cinder, etc. As soil.
Step 2 use water carefully
Pay attention to the water quality when watering, and don't water the flowers with water that can easily lead to flower hardening. If you want to use tap water, you should pay attention to let it stand and dry before using it.
3. Constant turquoise
Potted flowers must be loosened, because if they are not loosened, the soil will harden. When the soil is dry, it is easier to absorb water by loosening and watering.
4. Rational fertilization
When planting flowers, pay attention not to apply too much fertilizer. When applying fertilizer, apply as little as possible. Don't apply some non-decomposable fertilizers, and use more organic fertilizers. After decomposition, organic fertilizer can provide nutrients and loosen soil.
Third, how to deal with soil hardening
We need to water and fertilize reasonably in our daily life to avoid soil hardening. If soil hardening is found, attention should be paid to loosening the soil or replacing the basin soil in time. In addition, some dry fertilizers are applied to the soil surface, which can loosen the soil after fermentation. The method is to directly sprinkle dry fertilizer on the soil surface, not too thick. Spray water once after spraying. Generally, fertilization should be done once every two months.
