Choosing the Right Seeds

Preparing the Soil

Planting the Seeds
When to Plant: Plant sunflower seeds in the spring after the last frost date. In warm climates, you can also plant in the fall for a winter harvest.
Spacing: Plant sunflower seeds 6-12 inches apart in rows spaced 3-4 feet apart. Plant the seeds 1-2 inches deep in the soil.
Watering: Water the seeds thoroughly after planting. Keep the soil moist, but not soggy, until the seedlings emerge.
Caring for Sunflower Plants
Fertilizing: Fertilize sunflower plants once a month with a balanced fertilizer.
Watering: Sunflowers are drought-tolerant, but they will produce more seeds if they are watered regularly, especially during hot and dry weather.
Staking: Tall sunflower varieties may need to be staked to prevent them from toppling over.
Harvesting Sunflower Seeds
When to Harvest: Sunflower seeds are ready to harvest when the back of the seed head turns brown and the seeds are plump.
