Thank you for the great question.

Flowers can die for many different reasons. For instance, they can die because they did not get enough water or sunlight. Sometimes they can die from getting too much water as well! Some flowers grow, live, and die on a yearly schedule.

When a flower dies, the petals will become dry and brittle, and will shrink. Then the petals may fall off of the bulb, the center part of the flower. Bacteria then use the dead petals as food, and the petals then decompose and get added to the soil and dirt around the plant. This provides nutrients for the plant and its future flowers.
