Soil temperature: 70 - 75 degrees fahrenheit
Germination lighting: Dark required
Germination days: 4 - 8 days
Grow on temperature day: 55 - 60 degrees fahrenheit
Plant spread: 6 - 12 inches
Plant height: Max 60''
Plant type: annual

Loosen enriched garden soil down to a 6" depth. When soil is consistently 70 degrees (for zone 6-7 usually June 1st) plant seed 1/2" deep and a minimum of 6" apart. These are low maintenance and require nothing else other than weekly watering. Don't pinch like branching sunflowers as they are single stem. You can sow these sunflowers through late summer. We don't recommend you start sunflowers early in pots as they send a large tap root when germinating and in pots less than 6" deep will quickly become rootbound and not develop correctly.
The color of these sunflowers, and the overall vigor of the plant, is very dependent on sufficient soil nutrient levels. To achieve the deepest color we suggest you use a nutrient soil test to check your NPK and make sure your PH level is at least 7. A PH level under 6 will affect the color of the bloom.
