The weather has a huge influence on whether or not your dianthus plants grow back year after year. Sweet Williams are classified as annuals in Illinois, although they frequently overwinter in Arkansas, according to the University of Arkansas Division of Agriculture. This implies that instead of being completely killed by frost, they go dormant over the winter and blossom again in the spring. In general, dianthus plants are killed by repeated harsh freezes, as well as extremely hot conditions. Because of these factors, dianthus plants in temperate regions and well-draining soil are more likely to return and blossom year after year.
Do dianthus flowers come back every year?
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 do you get dianthus to rebloom?

How many years do dianthus last?

- Deadheading annual dianthus is extremely crucial to keep the plant from generating seeds and spreading. Do not deadhead if you want to collect seeds to develop more plants or if you want the plant to spread spontaneously in your garden.
- Using rubbing alcohol, sterilize the shears or scissor. This reduces the danger of disease transmission from plant to plant.

Do you cut dead blooms off dianthus?
The removal of dead blossoms from a plant is referred to as deadheading in horticulture. Deadheading can be done by pinching off the bloom by hand or with pruning shears, depending on the type of plant and the woodiness of the stems. Taking off dead blooms before they go to seed promotes the plant to blossom again. Pruning shears should be used to deadhead Dianthus, popularly known as carnation or sweet William. Because dianthus can re-bloom on each stem, deadheading it should be done with caution.
