The long-term storage methods of ginger are:

1. Store the ginger in a ventilated and cool place. Soak the ginger in water for about 20 minutes at regular intervals and let it breathe. Pour enough water, then dry it with paper towels, and still put it in a ventilated and cool place. This preservation method can be stored for several months.

2. Wrap the ginger with plastic wrap and store it in the refrigerator. This method can be stored for more than a month and is suitable for many families today.

3. Put the ginger in a flowerpot. Plant flowers normally in the flowerpot and keep the soil moist. Not only will the ginger not rot, but it will also grow new buds.

4. Wash the ginger and soak it in honey. Because honey is a natural preservative, it can prevent ginger from rotting and drying up. It is very convenient to take it at any time and use it at any time.

5. Clean the ginger and soak it in white wine. The white wine has antiseptic and air-isolating effects, which can prevent the ginger from rotting and drying up.

6. Bury the ginger in the sand, and spray the sand with water frequently to moisturize it. This method can store the ginger for more than half a year.
