Roses standing on the concrete floor, wrapped in newspaper, immersed in water, and/or water being poured over the flower heads now and then. It might not be common to treat roses like this, but it seems the way to keep them fresh at some market places in Bangkok, Thailand. At Phahurat Market, for example, where temperatures are high and without air conditioning, we saw it happen.

We asked a Thai vendor and he told us that not only roses, but other flowers are also watered like this, and that it doesn't damage the flowers. "Temperatures are high, so we need to keep them fresh." Also the fact that they are wrapped in paper would not affect the flower. "In a few minutes all will be dry again."
Is this really the best way to treat the flowers at market with such high temperatures?
