Growing Tips for South African Gardens 🌿

Soil: Plant in well-draining soil. If your garden has heavy clay, mix in sand and compost to improve texture. Mulching helps retain moisture and keeps the soil cool.

Sunlight: Full sun is ideal, though in the Highveld, a little midday shade reduces stress during peak summer heat.

Planting:

• Time: October – December.

• Depth: 8 cm deep with tubers pointed down.

• Spacing: 30–40 cm apart for airflow and healthy growth.

Watering: Water deeply every 3–4 days for around 10 minutes. Increase during very hot spells.

Feeding: Apply a quality bulb fertiliser (like Hadeco Bulb Food) regularly for stronger plants and larger blooms.

Care & Maintenance:

• Stake tall stems to protect against wind.

• Pinch back growth to encourage bushier plants.

• For show-stopping flower size, thin side buds to allow one main bloom to dominate.

• Watch for yellowing or mottled leaves – remove any affected plants quickly to prevent disease spread.

Dormancy & Lifting: From May to August, dahlias go dormant. Cut stems back to 5 cm in July, lift tubers carefully, and store them in a dry, cool place until spring.
