Plant hardiness varies depending on the species in the genus. The vast majority of Dianthus species grow well in the home garden and are ideal for planting and growing in USDA zones 3 to 9.
If you’re not sure whether the plants will make it through the winter, grow seedlings or take cuttings from the plant for the following season. During the growing season, most carnations reach a height of 24-inches, but sweet Williams only reaches 18-inches.
Pinks grow into 6- to 10-inch-high mounds, and alpine pinks are the smallest species in the genus, reaching only 4 to 6-inches in height. Dianthus alpinus is an excellent choice for rock gardens.
Short pinks that form mounds in the yard, as well as in window boxes and rockeries, create a captivating accent. Tall sweet Williams and carnations are best used in flowerbeds further back, where they can tower over other flowers and bushes, adding a layer of color to the area.

Dianthus dislikes getting its “feet wet,” hence it needs well-drained soil. The development of disease and root rot in the plant might be caused by overly saturated soil. To prevent diseases like white powdery mildew and rust, gardeners must ensure that the plant receives appropriate airflow through the foliage and blossoms.
Work some rich compost into the soil in the flowerbed before planting your Dianthus. Try to loosen the soil to a depth of 12 inches, then incorporate the compost into the soil thoroughly.

Gardeners should water their new Dianthus plants once a week at the very least, and let the soil dry out between waterings. Fertilize your Dianthus with a 20-10-20 ratio all-purpose liquid plant fertilizer. Late in the spring, you can also sprinkle a slow-release granular fertilizer around the base of the plant.
To avoid the production of seeds, gardeners must snip or pinch off the dead blooms and encourage a second wave of blooming before the end of the growth season. Gardeners should trim back flower stems to the ground at the end of the growth season.
Place a 4-inch layer of mulch around the base of your Dianthus before the first frosts reach the ground for extra winter protection. After the last frosts have passed, remove the mulch and let the plant to begin its growing season.
