Annual dianthus tolerates minor frost well, but strong freezes can be damaging. Dianthus can be grown as a winter annual in milder climates.
How cold can dianthus survive?
Whether you have perennial or annual dianthus will determine this. Perennial dianthus is very cold hardy, ranging from -20 to -30 degrees Fahrenheit depending on cultivar. The leaves of perennial dianthus are silvery gray in tone and resemble grass blades. The leaves of the annual dianthus are dark green and flat. Annual dianthus is only hardy to about 30 degrees Fahrenheit. Many individuals, though, believe it is perennial. It isn’t the case. The reason they get plants again the next year is because they reseed, not because they come back from the roots, as perennials do. If planted in a window box or container, a plant that is ordinarily cold hardy to zone 0 (zone 7) must be hardy to zone 6. Your first line of defense against cold damage is water. You could instead use a sheet, burlap, or another textile instead of plastic. At Walmart, every annual product has a UPC that is highlighted in red. A UPC was outlined in purole on every perennial product. Whether at Walmart, Lowe’s, or Depot, all plant tags should clearly state “Annual” or “Perennial.” If it doesn’t, it may have fallen out; examine other pots in the vicinity of the one you wish to buy. If none of them have it, the tagging process at the supplier may have been overlooked. The UPC also includes the names of all suppliers. If your plant doesn’t have a tag, you can call the supplier with a full description and they should be able to tell you if it’s an annual or perennial.

The excellent flower for giving both early and late splashes of color to your landscape, dianthus blooms in colors ranging from lilac to deep pink in the spring and again in the autumn. Alpine dianthus types are hardy enough to withstand cold and fast-draining soil, but keep in mind that all dianthus require sunlight and do not tolerate shadow well.

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.
All Dianthus species thrive in locations of the garden that receive direct sunlight throughout the day. Gardeners who plant in places with afternoon shade may notice that their plants flower later and with less vigor.
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. Add another 1-inch top-dressing around the base of the plant in the spring to help the plant with the blossoming phase by driving additional nutrients into the soil.
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.
