Select a big pot with drainage holes. Sunflowers have long roots, so the pot should be at least 12 inches deep and wide enough to allow proper growth.

Plant sunflower seeds about 1 inch deep in the soil. Space them out, leaving at least 6 inches between each seed. Press the soil gently over the seeds.
