Cosmos bipinnatus Cosimo Pink White | Garden Cosmos | H 50–60 cm

Growing Instructions

Sowing Indoors:

• Sow from March to April in trays or pots under cover (18–22 °C).
• Cover seeds lightly with fine compost or vermiculite.
• Germination takes 7–14 days.

Transplanting:

• Prick out seedlings when large enough to handle and grow on in cooler conditions (10–15 °C).
• Harden off and plant outdoors after the last frost (mid-May onwards).

Sowing Outdoors:

• Alternatively, sow directly into well-prepared soil from late April to May. Thin seedlings to 25–30 cm spacing.

Site Requirements:

• Position: Full sun.
• Soil: Well-drained, moderately fertile soil. Avoid over-fertilizing, as this promotes foliage over flowers.
• Watering: Regular but moderate watering; drought-tolerant once established.

Flower Care:

• Deadhead regularly to encourage continuous flowering.
• Ideal for cutting – stems last up to 7 days in a vase.
