How to sow and grow African Marigold Sierra Gold

• Sowing method: seedlings or direct
• Depth: 0.5–1 cm
• Spacing: 30–40 cm
• Germination: 5–8 days at 20–25 °C
• Position: sunny spot

Sow seeds on the surface of the compost and cover with a very fine layer of dry vermiculite or finely sieved compost. In a temperate climate, place the seeds in a propagator or seal in a polythene bag and keep at about 21-25°C until the seeds germinate. This will take about 7-21 days. Do not exclude the light, as it helps germination. When the seedlings are large enough to handle, transplant them individually into 7.5 cm pots or multi-cell trays. For temperate climates, before planting out, acclimatise the plants to cooler conditions by leaving them outside for a few hours a day for a few weeks. Plant out when all risk of frost has passed, about 30 cm apart.

Sow for seedlings in March–April, or directly after the last frosts. Plant in sun; remove spent flowers for abundant blooms.
