Growing Red Sun Sunflower

Indoor Sowing: Not Recommended.

Direct Sowing: Late Spring and Early Summer.

• Sunflowers need full sun; they need on average 6-8 hours of direct sunlight per day – the more the better if you are trying to grow them to their maximum potential.
• They grow best at temperatures between 18–33ºC.
• Plant the seeds in holes or trenches one seed 2.5 cm deep, or 5 cm if the soil is loose and sandy.
• Keep seeds at least 30 cm from each other, to give each one enough space to grow.
• Cover the seeds with soil after planting.
• If the soil is kept moist, seedlings will appear within 5-10 days.
• The plants need to be staked and supported, especially when in flower.
