The Q&A Archives: shearing dianthus

Question: I have several varieties of dianthus planted in containers throughout my yard but it seem when I remove the dead flowers nothing grows back in its place. How do I properly shear or get rid of the dead flowers for regrowth? 2 examples are Barbarini Red Dianthus and Corona cherry magic dianthus. They were so beautiful when I bought them I would like them to last. Also, when winter comes to I cut them down completely or just remove dead flowers and cover, sorry I am a new gardener. Thanks!

Answer: The best way to keep your dianthus looking nice is to take a pair of scissors and cut the tops off, just below the lowest spent flower. Dianthus won't bloom a second time if they are not deadheaded because when the flowers fade the plant spends all of its energy making seeds. If you shear the tops of the plants off as the petals fade but before seed pods begin to develop, your plants will rebloom later in the summer.

Hope this answers all your quesitons.
