Sunflower 'Incredible'

Try to plant in a location that enjoys full sun and remember to water often. Keep in mind when planting that Incredible is thought of as half hardy, so remember to watch your frost dates and ensure you have this plant protected when the temperature dips. Incredible requires a loamy and clay soil with a ph of 5.7 - 8.1 - it grows best in weakly acidic soil to weakly alkaline soil.

Ensure a distance of 4.68 inches (12.0 cm) between seeds when sowing - look to sow at a depth of approximately 0.49 inches (1.25 cm). Soil temperature should be kept higher than 13°C / 55°F to ensure good germination.

By our calculations, you should look at sowing Incredible about 21 days before your last frost date.

Ensure that temperatures are mild and all chance of frost has passed before planting out, as Incredible is a half hardy plant.
