Dahlia Large Clump - Yvonne
Yvonne is a soft, elegant decorative dahlia valued for its clean colour tone and excellent performance as a cut flower. It produces medium to large, fully double blooms in a warm soft orange to apricot-orange shade, sometimes with subtle tonal variations as the flower matures. The colour is gentle yet warm, making it a versatile choice for both floral arrangements and garden planting.

Dahlia Clumps – How They Work
________________________________________
A Dahlia clump is a cluster of Dahlia tubers that grow together, producing multiple plants from a single clump. Each clump contains several tubers and, when planted, will produce an average of 2–10 healthy Dahlia plants (depending on variety and growing conditions).
We sell these clumps ready for planting, providing an easy and efficient way to create a beautiful, full display of Dahlias in your garden.
Tip: You can divide your clumps if you’d like to plant tubers separately for more individual plants—there are several helpful videos on YouTube showing how to do this. If you prefer, you can plant the whole clump for a single, big, strong plant.

Top Tips for Planting Dahlia Clumps
________________________________________ 1. Site & Sunlight Plant in a full sun position (6–8+ hours daily) with well-draining soil to prevent rot and encourage strong growth. 2. Planting Time Plant when night temperatures are consistently above 10–12°C (generally from September in most parts of South Africa). 3. Planting Method Place clumps horizontally about 10 cm deep and 40 cm apart. Position the growing eyes facing upwards and cover lightly with soil, ensuring no air pockets. 4. Soil & Watering at Planting Plant into moist soil. Avoid waterlogged or completely dry soil. Maintain consistent moisture until shoots emerge. 5. Watering After Emergence Once green growth appears, increase watering gradually. Allow the soil to dry slightly between watering, but never completely dry out. 6. Support (Netting Essential) Install netting early (often 2 layers) to support upright growth, prevent bending, and ensure even plant structure and yield. 7. Pinching Pinch plants once they reach ±30 cm to encourage bushier growth and more flowers. 8. Spacing Allow ±40 cm spacing between plants for good airflow and healthy development. 9. Fertilising & Protection Use fertiliser and Plant Protection Products (PPP) as per programme guidelines. Apply only to dry plants and avoid tank mixing incompatible products. 10. PPP Best Practice • Avoid spraying in temperatures above 28°C • Rotate chemical groups to prevent resistance • Do not mix copper with other products • Avoid “cocktail” sprays of multiple products 11. Organic Option Bioneem can be used as a softer, organic pest deterrent option. 12. Deadheading Remove spent flowers regularly to encourage continuous blooming. 13. Growth & Season Dahlias are tender perennials, typically flowering from December to April, reaching ±90–120 cm in height. |
