Deadheading Dianthus: How to Encourage Repeat Blooms

Your dianthus put on a beautiful show, but now the spent blossoms have turned brown. Should you remove them? Yes—and the technique matters for future flowers.

Precision Deadheading for More Blooms

Examine the base of each flower stem. If you see small green buds forming, use scissors to snip just above those buds. These lateral buds will develop into new flower stems, giving you another flush of blooms later in summer.

The "Wholesale" Approach

If checking each stem feels too tedious, shear off all spent flowers at once. The plant may still produce sporadic summer blooms, though less prolifically. Either way, regular watering and fertilizing will support reblooming.

General Dianthus Care

• Sun: Full sun (6+ hours) for best flowering.
• Soil: Well-drained, slightly alkaline soil.
• Water: Water at base to keep foliage dry; avoid overhead watering.
• Fertilizer: Light application of balanced fertilizer in spring.
