Why is deadheading important

Deadheading is an important task to keep up with in the garden throughout the growing season. Most flowers lose their attraction as they fade, spoiling the overall appearance of a garden or individual plants. As flowers shed their petals and begin to form seed heads, energy is focused into the development of the seeds, rather than the flowers. Regular deadheading, however, channels the energy into the flowers, resulting in healthier plants and continued bloom. Snapping or cutting dead flower heads can enhance the flowering performance of many perennials.

It encourages new growth and far more blooms! 🌹 Otherwise some plants will "go to seed."

Most people think plants look better with spent blooms removed, deadheading also promotes more blooms. I also find I have less problems with plant pests (aphids, mealybugs, etc) when I deadhead regularly.

It Promotes additional growth and flowering.

When some plants are allowed to "go to seed", it acts as a trigger to the plant that it's job is done and no further seed production (flowers) is necessary

I agree with Connie...plus the plant is putting all its energy into creating the seeds instead of creating more flowers.

deadheading eliminates the need to supply nutrients to the dead flower and stimulates the plant roots. It's the reason to trim back bushes once a year. It renews your plants and stimulate new and healthy growth.
