Plant 2 to 3 seeds per spot in case one gets eaten. Once they have sprouted, thin out to keep the strongest plant.Planting. Sunflowers are annual plants that perform best in sunny locations. They can be easily started from seed by directly placing seeds into the ground. Sunflowers can also be started indoors as transplants, which allows for them to bloom earlier than direct seeding.Sunflowers thrive in warm weather and on sunny days.
