Sowing and planting in South Africa 🌱

• When to sow: After the last frost.

  • Gauteng/Highveld: AugNov

  • KZN/Lowveld & Coastal: AugDec

  • Western Cape: SeptJan
    Frost-free areas can sow into late summer for autumn colour.

• How to sow: Direct sow where they are to flower (best). Sow 510 mm deep, keep moist. Germinates in 510 days at 2026 °C.
  Starting in trays is fine for an early jump; transplant gently at 23 true leaves and disturb roots as little as possible.

• Spacing: 3040 cm between plants for airflow and strong stems.

• Succession: Sow every 23 weeks for non-stop blooms right through summer.

Light and soil 🌿

• Full sun (68+ hours daily) gives the biggest flowers and longest stems.

• Soil: Well-drained, compost-enriched soil (neutral to slightly acidic).

• Feeding: A light, balanced organic fertiliser gets them moving; avoid over-feeding nitrogen which reduces flowering.

Watering 💧

• Keep seedbeds evenly moist until established.

• Once growing, water deeply 12 times per week depending on rainfall.

• Water at the base; keep leaves dry to limit powdery mildew.

Pro tips for lush plants 🛠

• Pinch once at 2530 cm to encourage bushy plants and more flower stems.

• Mulch to hold moisture and keep roots cool.

• Deadhead or keep cutting to extend flowering for months.

• Give good airflow; avoid crowding to reduce mildew pressure.

• For the vase: cut when petals are mostly open and the stem feels firm; expect 710 days of vase life.
