Revitalizing Carnations & Dianthus: Clean Up, Feed & Mulch for Lush Blooms

Spring Renovation for Perennial Dianthus

Carnations and large pinks (Dianthus) need annual hygiene and feeding to stay compact and floriferous.

Step-by-Step Spring Routine

1. Remove all dead foliage – Cut back to the crown once hard frost has passed. This eliminates disease/pest overwintering sites.
2. Side-dress with well-composted manure – Apply a 1-inch ring around each plant (not touching stems). Cow, horse, sheep, or goat manure is ideal; use chicken manure sparingly (can burn).
3. Mulch lightly – 1 inch of fine bark or compost suppresses weeds and retains moisture.
4. Deadhead religiously – Snip spent flowers to just above a leaf node; this redirects energy to new buds.

Ongoing Care

• Full sun (6+ hours) and sharp drainage are non-negotiable.
• Water at base; avoid wet foliage.
• Divide clumps every 3–4 years in early spring to prevent center die-out.

Neatness + rich organic food = the "Joneses" garden you want.
