1、 What if the soil hardens

1. Timely soil change: when raising flowers and plants, you should change the soil frequently. Generally, the soil should be changed once a year or two or three years. Replace the soil with loose, breathable and fertile soil, and loosen the soil frequently during management, which can avoid soil hardening and promote the plants to better absorb water and nutrients

2. Add microbial agents: when managing watering, the microbial agents in the soil will be washed away, and many microorganisms will flow out of the drain, and the soil will harden over time. Microbial agents and bacterial agents should be added to the plant regularly, about once every three months, so as to avoid hardening

3. Scientific fertilization: if inorganic salt fertilizer is often applied during management, it is easy to harden after a long time. Pay attention to the application of organic fertilizer, less inorganic salt, and foliar fertilizer, so as to avoid hardening and reduce the damage to the soil

2、 How to prevent hardening

Usually, when breeding plants prepare soil, they should mix an appropriate amount of cinder, fermented sawdust or crushed charcoal in the soil, which can improve the air permeability of the soil and avoid hardening. If possible, you can find some rotten leaf soil to mix in. Pay attention to drying before use to avoid insect eggs or bacteria. In addition, if you use tap water when watering, you should dry it for a day and then volatilize the chlorine contained in it, so as to avoid hardening
