Full Answer

  1. Prepare the soil

    Turn the soil in the garden to form rows that are 2 to 3 feet apart, and mix a slow-release fertilizer into the soil if the soil quality in the region is poor.

  2. Plant the seeds

    Plant sunflower seeds 6 inches apart directly in the garden when the soil temperature reaches 55 to 65 degrees Fahrenheit, or up to 2 weeks before the final expected frost of the season. Cover each seed with 1 to 2 inches of loose soil, and water each seed thoroughly. Continue to water the seeds daily until sprouts appear. Thin the plants to 2 feet apart after the second set of leaves develop.

  3. Provide continuing care

    After sprouts appear, cover the sunflowers with several inches of natural mulch, such as cedar mulch, to maintain moisture levels and to reduce weed growth. Stake the sunflowers after the plants reach 3 feet high to prevent breakage, and provide the plants with plenty of water throughout the growing season.
