Can urea be applied when caring for flowers?

Flowers can be given urea, but it should not be applied in too large an amount. When applying urea to flowers, you can generally use a bamboo stick to poke some holes in the soil in the flower pot, about 5-8 cm deep, then put the urea granules in, about 20 granules each time; alternatively, you can dilute the urea in water and then spray it on the leaves of the flowers, once or twice a week.
