Planting Sunflower Seeds
It's easiest to sow seeds directly into the soil after the danger of spring frost is past. Ideally, the soil temperature has reached 55 to 60 degrees F.
Plant the large seeds no more than 1 inch deep and 4 to 6 inches apart in well-dug, loose soil after it has thoroughly warmed, from mid-April to late May.
A light application of fertilizer mixed in at planting time will encourage strong root growth to protect them from blowing over in the wind.
Experiment with plantings staggered over 5 to 6 weeks to keep enjoying continuous blooms.
Give plants plenty of room, especially for low-growing varieties that will branch out. Make rows about 30 inches apart. (For very small varieties, plant closer together.)
When the plants are six inches high, thin them to two feet.
If you see birds scratching around for the seeds, spread netting over the planted area until seeds germinate.
