WHEN TO PLANT SUNFLOWERS
It’s best to sow sunflower seeds directly into the garden (or outdoor containers) after the danger of spring frost has passed anytime after soils have warmed to at least 50°F (10°C).
In most regions, this will fall between April and mid-July. In the south, this will probably occur in mid-March or early April. 
Sunflowers dislike having their roots disturbed, which is why we recommend direct-sowing instead of transplanting.
CHOOSING & PREPARING A PLANTING SITE
Find a sunny spot! Sunflowers grow best in locations with direct sunlight (6 to 8 hours per day); they require long, hot summers to flower well.
Choose a location with well-draining soil. It shouldn’t pool water after it rains.
Sunflowers aren’t picky but the soil can’t be too compact. They have long tap roots that need to stretch out; in preparing a bed, dig down 2 feet in depth and about 3 feet across.
They’re not too fussy when it comes to soil pH either. Sunflowers thrive in slightly acidic to somewhat alkaline soil (pH 6.0 to 7.5).
