“Regular deadheading maintains a plant’s appearance and improves its overall performance,” Kelly Wilkniss, gardening expert and host of My Soulful Home on Smart Healthy Green Living, tells mbg.
Once flowers start to fade, plants start to turn their attention to generating seeds instead. “At that time the plant’s energy is focused on the development of the seeds rather than the flowers,” Wilkniss explains.
By removing dead flowers, you’re telling your plant to keep producing new flowers instead of putting all its energy into seeds. “This results in healthier plants and a second or perhaps continual blooms,” she adds.
In short, deadheading helps your garden produce more flowers and stay in bloom for longer, which is great for you and your local pollinators.
