If youre more of a hands-off gardener, deadheading isnt strictly necessary with dianthus.

How To Deadhead Dianthus
Use garden snips to cut off the faded flower head.
Cut individual stems back to the level of the foliage.
If you have a lot of dianthus flowers, theres also a faster method for deadheading.
Tiny, stubby stems may remain, but they wont affect new flowering.
Snip the stems while the flowers are still in full bloom and havent started to wilt.
Some types of dianthus last for weeks in the vase if you change the water regularly.
Shearing back the entire plant also can be helpful if its beginning to look leggy.
Cutting it back to remove the shaggy parts will regenerate new, more compact growth.
