Sunflower 'Del Sol Hybrid'

Try to plant in a location that enjoys full sun and remember to water often. Del Sol Hybrid is generally regarded as a half hardy plant, so although it can survive a small mild cold snap, it is wise to ensure that this plant is protected from frost damage. Del Sol Hybrid needs a loamy and clay soil with a ph of 5.7 to 8.1 (weakly acidic soil to weakly alkaline soil).

Sow 0.49 inches (1.25 cm) deep with a guideline distance of 4.68 inches (12.0 cm). For optimal germination, soil temperature should be a minimum of 13°C / 55°F.

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

Del Sol Hybrid is half hardy, so ensure you wait until all danger of frost has passed in your area before considering planting outside.

The botanical epithet is from the Latin annuus meaning “annual”.¹
