Black seed sunflowers are also referred to as black oil sunflower seeds. The seeds grow into tall, sturdy, beautiful sunflowers and produce even more seeds at harvest time. Their seeds can be enjoyed as a snack for you, or your wild backyard friends. But before you get to harvest time, there are a few steps you should follow in order to plant black seed sunflowers that will flourish.
Decide on an area to plant your sunflower plants. It's best to choose an area near a fence or some posts so you have something to anchor the plants to in order to protect them from the wind. Your sunflowers also need to be planted in an area that has at least six hours of sunshine and good soil drainage.
Break up the ground after all danger of frost has passed. Remove the sod with a shovel and then use a hoe to loosen the dirt.
Dig a row 12 inches wide and 2 inches deep. Water the row that you have dug, and allow the water to drain into the soil.
Place your black sunflower seeds in the trench, spacing the seeds 6 inches apart. Cover the seeds with 2 inches of soil and gently pat the soil down. Keep the soil moist, but not drenched.
