Sunflower 'Yellow Disk'

Yellow Disk likes a position of full sun and remember to water often. Yellow Disk is generally regarded as a half hardy plant, so remember to protect this plant from frosts and low temperatures. Yellow Disk needs a loamy and clay soil with a ph of 5.7 to 8.1 (weakly acidic soil to weakly alkaline soil).

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). For optimal germination, soil temperature should be a minimum of 13°C / 55°F.

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

Yellow Disk 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
