Dianthus, also known as pinks, are beloved flowering plants that adorn gardens with their vibrant blooms. As they mature, dianthus plants may become overcrowded, reducing their flowering capacity and overall health. To rejuvenate your dianthus and increase your plant stock, splitting is an essential technique. This comprehensive guide will walk you through the process of how to split dianthus plant, ensuring successful propagation and thriving blooms.
Why Split Dianthus Plants?
- Rejuvenation: Splitting overcrowded plants stimulates new growth, enhancing their vigor and flowering potential.

Step-by-Step Guide to Splitting Dianthus Plants
1. Prepare the Plant
- Gently loosen the soil around the dianthus plant using a spade or trowel.
- Remove the plant from the ground and shake off excess soil.
2. Divide the Root Ball
- Using a sharp knife, carefully divide the root ball into sections. Each section should have a healthy portion of roots and at least one stem.
3. Remove Dead or Diseased Roots
- Inspect the roots and remove any that are dead, damaged, or diseased.
4. Plant the Divisions
- Fill a pot or planting bed with fresh potting mix.
- Dig a hole deep enough to accommodate the roots of the dianthus division.
- Place the division in the hole and fill in the soil around it, gently firming it down.
5. Water Thoroughly
- Water the newly planted dianthus divisions deeply to settle the soil and encourage root growth.
6. Fertilize (Optional)
- If desired, you can fertilize the new plants with a balanced fertilizer to support their growth.
7. Aftercare
- Keep the soil moist but not waterlogged.
- Protect the new plants from direct sunlight during the hottest part of the day.
- Monitor the plants for any signs of stress or disease.
Tips for Success
- Use a sharp knife to avoid damaging the roots.
- Divide the plant into sections with at least three to five stems each.
- Replant the divisions in well-draining soil.
- Water the plants regularly, especially during the first few weeks after splitting.
- Mulch around the plants to retain moisture and suppress weeds.
Wrapping Up
Splitting dianthus plants is a rewarding technique that rejuvenates existing plants, creates new ones, and improves their overall health. By following these steps and providing proper aftercare, you can successfully split your dianthus and enjoy their vibrant blooms for years to come.
