The White Cactus Dahlia is a showstopper in any South African garden. With its spiky, starburst petals and soft ivory glow, it brings a sense of drama and sophistication to borders, beds, and cut flower displays.

Growing Tips for South African Gardens 🌱

Soil: Plant in rich, well-draining soil. If your garden soil is heavy with clay, mix in sand and compost for best results. Add mulch to help retain moisture.

Sunlight: Loves full sun but will also tolerate light midday shade in very hot inland regions.

Planting:

• Season: October – December.

• Depth: 8 cm, with tubers lying flat.

• Spacing: 30–40 cm apart for strong growth.

Watering: Water deeply every 3–4 days. Avoid overwatering or soggy soil.

Feeding: Enrich with Hadeco Bulb Food throughout the growing season.

Care:

• Pinch young shoots to encourage bushy growth.

• Stake taller stems to prevent flopping.

• Deadhead regularly for more blooms.

• Lift tubers in July, cutting stems back to 5 cm, and store in a cool, dry place until spring.
