These plants are perennials with a short life span, although they are commonly planted as annuals in Missouri and other colder climates. Annuals have a single growing season. Many Dianthus types, on the other hand, self-seed every year. That is to say, they re-grow each spring.
How many years do dianthus last?

If you wait until after the plants have blossomed for the first time, you can deadhead them so that the energy isn’t squandered on flower production and can be used to create new root systems following transplanting. Plants should not be divided late in the growth season because they will not have enough time to create new roots before going dormant for the winter. The optimum time to divide the plants is in the morning, when the roots are more hydrated and less prone to injury.

For the first month, water the young plants at least once a week to aid in their establishment.
