She added that a tonne of flowers was being placed daily outside the palace by mourners.
The King passed away peacefully in his 89th year on October 13.
“These flower represent the love and faith of the loyal Thai subjects for their beloved King Rama IX and should not be uselessly wasted in the garbage, so the Bangkok Metropolitan Administration’s top officials decided to transform the flowers into natural fertiliser instead to derive the most benefit from them.”
She said King Rama IX Park had prepared a space where the palace flowers would be converted to fertiliser, which will be used to nourish live flowers in parks across Bangkok.
She said other groups planned to use flowers left in honour of the King for other useful purposes, but she added that resulting products should not be sold.
“Some people have planned to transform the flowers into potpourri and distribute it to public. I think that is a good and creative idea,” she said.
