  • Planting Instructions

    When to Plant Sunflowers

    It is recommended to sow your sunflower seeds directly into your garden rather than start them in starter pots. Sunflowers send down long taproots that can be stunted in small pots. Once all danger of frost has passed and both daytime and nighttime temperatures reach 55F to 60F you are ready to sow your sunflower seeds.

    Where to Plant Sunflowers

    Sunflowers grow best in full-sun locations – receiving at least 6 to 8 hours of full sun exposure per day. Though sunflowers are not finicky, they do appreciate loose, well-draining soil. Choose a location that is sheltered from strong winds, perhaps along a fence or near a building. Also consider the height that the particular variety will reach.

    How to Plant Sunflowers

    Once you have chosen your location, dig down to a depth of 2 inches and turn the soil over to loosen it. Many seeds, like poppies, need sun to germinate. This is not the case with sunflowers and in fact need to be pressed 1 inch deep into the soil. If left on the soil surface, more than likely birds will come and eat them before they ever get anywhere close to germination. Final spacing should be 36” apart for giant sunflowers, 24’ apart for regular-sized and 12” apart for miniature varieties.

    Caring for and Harvesting Sunflowers

    Sunflowers are usually problem-free. Plant early enough so that autumn frosts do not cut your sunflowers’ life cycle short. Too much rainfall before and after germination can cause the seeds to rot or bring on downy mildew. Be sure to seed after the rainy season to avoid this.

    If you would like to harvest the seeds to either replant next year, wait until the end of the bloom cycle. Sunflowers blooms often last 30-45 days. Toward the end of this period, the green back of the flower head will begin to turn yellow and will usually droop at this time. You will also see the seeds swelling on the face of the sunflower. Cover the flowers with paper bags to protect them from birds. Cut off the flower heads and leave inside the brown paper bag. Store this bag in a well-ventilated place like a garage until fully dry. Rub along the seeds with the palm of your hand and the seeds should fall right out into your bag, or work over a cookie sheet. Store seeds in a cool, dry environment until you are ready to reseed next year.

    To eat: Soak overnight in water, or salt water. Drain, spread on a shallow baking sheet, and roast for 3 hours at 200F or until crisp.

red sunflowers

I reordered these seeds for next summer. I loved these in my garden. The bees and hummingbirds also love them. They have bloomed all summer long. They have sturdy stems but they do take up a lot of space. It is October and some are still in bloom. They are easy to grow, I just threw seeds in my gardens , no pampering needed.
