Should I soak sunflower seeds before planting?
We recommend our USA Grown Raw Organic Sunflower Seeds. Start the process by soaking the seeds for 11/2 – 2 hours at room temperature. A good ratio will be about half to one cup sunflower seeds with two cups water. Next, drain and rinse the seeds thoroughly (you’re getting rid of that pesky phytic acid!).
Can you just scatter sunflower seeds?
For many kinds, yes. Find out when the plants normally set seeds, and scatter then, or just before a good rain after that time. I usually sow in the fall after it has rained some, but more is expected, so that the seeds stay where I toss them.

How many sunflower seeds to plant per hole?
How to Sow. Sow single stem, large- headed sunflowers as 3 seeds every 1’–2′ apart and ¼”–½” deep. Sow multi-stem sunflowers 2′ apart. Professional cut-flower growers reduce this spacing by half resulting in longer stems and smaller flowers, which are more desirable for bouquets.

What happens if you plant sunflowers too close together?
If you plant closer, you might get taller stalks but smaller heads. If you plant farther apart, the seed head may be larger, but possibly too heavy for the stalk to bear. If you have limited space, Tom recommends sowing in a small clump that will eventually be thinned to one plant.
How do I prepare my soil for sunflowers?
Sunflowers thrive in slightly acidic to somewhat alkaline soil (pH 6.0 to 7.5). Sunflowers are heavy feeders, however, so the soil needs to be nutrient-rich with organic matter or composted (aged) manure. Or, work in a slow release granular fertilizer 8 inches deep into your soil.

Mulching: Mulching sunflowers is not necessary; however, those dealing with dry climates may choose to do so.
