What technique is utilized with the gel-like substance for conditioning flowers?

The correct choice involves the technique of submerging when conditioning flowers with a gel-like substance. Submerging refers to placing the stems of the flowers directly into the gel, allowing the plant material to absorb moisture and nutrients effectively. This method is particularly beneficial because the gel can provide hydration without the risk of the stems rotting, which might happen with traditional water soaking.

Additionally, the gel substance often contains beneficial compounds that can extend the life of flowers by keeping them hydrated and nourished. This approach is especially useful for delicate or tropical flowers that may require specific hydration techniques.

The other methods, such as soaking or spraying, while they serve to hydrate plants, do not utilize the unique properties of the gel or allow for the extended hydration that submerging provides. Injection, on the other hand, typically refers to introducing water or nutrients directly into the stem, but it does not utilize the gel-like substance effectively for conditioning purposes. These distinct characteristics make submerging the most appropriate choice for conditioning flowers using a gel.
