The stems of flowers are fibrous, much like a banana peel or a piece of celery. When you grind up the stems in the garbage disposal, those fibrous strands can get caught in the blades of the garbage disposal or form a clump of fibrous strands in the pipes of the system, somewhat like a clump of hair might clog a shower drain.
Seeds can clog a garbage disposal easily. Therefore, any flower with a seed-like or seed center should not be ground in the garbage disposal. Opt to throw away the bloom instead.
Other fibrous foods and items that have a similar effect on a garbage disposal and can create a clog are eggshells, corncobs, bones of any kind and banana peels.
Composting is a safe, resourceful way to dispose of your perishing flowers and is an especially good option if you are a gardener. You can create organic material for your garden bed. Composting is 100 percent natural. Simply toss the flowers into your composting bin, which should be located outside if at all possible. Over time the flowers will return to a soil-like composition. You can use this material to enrich your plants, and your garbage disposal will remain clog-free.
