Try to plant in a location that enjoys full sun and remember to water often. Keep in mind when planting that Sunseed is thought of as half hardy, so remember to protect this plant from frosts and low temperatures. Ensure your soil is loamy and clay and has a ph of between 5.7 and 8.1 as Sunflower is a weakly acidic soil to weakly alkaline soil loving plant.

Growing Sunseed from seed

Try to aim for a seed spacing of at least 4.68 inches (12.0 cm) and sow at a depth of around 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 Sunseed about 21 days before your last frost date.

Transplanting Sunseed

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