Dianthus (S, F)
Plugs should be transplanted into a pot so the original soil line of the plug is even with the surface of the growing medium of the new container or directly into the garden at the same depth. Plant in spring or fall, spacing plants 6 to 12 inches apart, depending on the type.
Prepare the garden bed by loosening soil to a depth of 12 to 15 inches, then mix in a 2- to 4-inch layer of compost. Be careful not to plant the crown too deeply as this can cause crown rot. Carefully fill in around the root ball and firm the soil gently. Water thoroughly.
Prefers full sun and can be grown in part shade but will have fewer flowers and its foliage will not be as lush. Once established Dianthus can tolerate dry, hot locations. If deadheaded they will rebloom in fall. Firewitch: Zone 3-9. Raspberry Swirl: Zone 5-9.
