Explanation:

Moss peat is used as a packing material for sending flowers and live plants to distant places because it is hygroscopic.

Hygroscopic Nature of Moss Peat:
- Moss peat has the ability to absorb and retain moisture. This makes it an ideal packing material for flowers and live plants as it helps to maintain the moisture content during transportation.
- Flowers and plants require a certain level of moisture to survive, and transpiration (the loss of water through the leaves) can be a significant issue when they are being transported over long distances.
- Moss peat acts as a moisture reservoir and helps to prevent excessive water loss through transpiration, keeping the plants hydrated and reducing the risk of dehydration during transportation.

Advantages of using Moss Peat as a Packing Material:
1. Moisture Retention: Moss peat has high water-holding capacity, which helps to keep the flowers and plants hydrated by providing a steady supply of moisture.
2. Reduction of Transpiration: The hygroscopic nature of moss peat reduces transpiration, minimizing water loss and preventing wilting or dehydration of the plants during transit.
3. Cushioning Effect: Moss peat provides a cushioning effect, protecting the delicate flowers and plants from damage during transportation. It helps to absorb shocks and vibrations, reducing the risk of breakage or damage to the foliage.
4. Lightweight: Moss peat is lightweight, which is beneficial for transportation purposes. It adds minimal weight to the package, reducing shipping costs and making it easier to handle.
5. Natural and Environmentally Friendly: Moss peat is an organic and natural material, making it a sustainable choice for packaging. It is biodegradable and does not pose any harm to the environment.

Conclusion:
Moss peat is the preferred packing material for sending flowers and live plants to distant places due to its hygroscopic nature. It helps to retain moisture, reduce transpiration, provide cushioning, and is lightweight, making it an ideal choice for protecting and preserving the plants during transportation.
