Can rapeseed cake be soaked in water to water flowers?

Rapeseed cake cannot be used to water flowers directly after being soaked in water, because rapeseed cake contains a certain amount of oil. If it is not decomposed and fermented, the roots of the flowers will not be able to absorb a large amount of oil.

If you soak the rapeseed cake in water and then use it to water the flowers directly, it will ferment on its own in the potting soil. The rapeseed cake will generate a lot of heat during the fermentation process, which will cause the roots of the flowers to be burned directly. In addition, the rapeseed cake will breed various bacteria during the fermentation and will also eat the tender roots of the flowers.
