How to Plant Red Sunflower from Seed

When to Plant Seeds

  • Cool Climates: Direct sow seeds outdoors after the last frost date.
  • Warm Climates: Can be planted throughout spring and summer.

Preparing the Planting Site

  1. Choose a sunny location with well-draining soil.
  2. Loosen the soil and mix in compost or organic matter for added nutrients.
  3. Space plants 12-24 inches apart, depending on variety size.

Starting Seeds

Outdoors (Recommended for Best Results): Plant seeds ½ inch deep and 6 inches apart. Water gently to moisten the soil but avoid waterlogging. Germination occurs in 7-14 days, depending on temperature.

Indoors: Start seeds 2-3 weeks before the last frost. Use peat pots or biodegradable seed trays to prevent root disturbance. Transplant seedlings outdoors once they have 2-3 sets of true leaves.

Thinning Seedlings

  • Once seedlings are 3-4 inches tall, thin them to 12-24 inches apart.
  • This ensures stronger plants with better airflow.

Pro Tip

For giant blooms, feed them with balanced fertilizer during the growing season.

Bonus: To attract more pollinators, plant multiple varieties for a longer bloom period!

Getting to know your Red Sunflower

Red sunflowers are striking varieties of the common sunflower, featuring deep red to burgundy petals surrounding dark brown centers. They grow 5-8 feet tall in full sun and well-drained soil. Like traditional sunflowers, they follow the sun’s movement during the day (heliotropism). These sunflowers attract pollinators and produce edible seeds. They require regular watering but are drought-tolerant once established.

Our Seed Safety Promise

We do not sell genetically modified seeds — ever. And we don’t use genetic engineering to breed new varieties. Instead, our skilled breeders use traditional, natural crossing methods to create hybrid seeds that are healthy, safe, and packed with potential.

Our Seed Quality Guarantee

At Shido, we believe great gardens start with great seeds — and that means quality comes first. Every seed lot we offer is ensure to generate top-notch germination because your garden deserves nothing less.

To keep our seeds at their peak, we run thorough pathology tests at trusted outside labs. When you open a Shido seed packet, you can trust it’s been nurtured, tested, and approved to give you strong, healthy plants from the very first sprout.

Types of Seeds We Offer

Hybrid Seeds (F1)

F1 hybrid seeds are the garden’s high achievers — created by crossing two specially chosen parent plants for superior vigor, uniformity, and performance. We use only traditional breeding methods to produce these powerhouse seeds.

Open-Pollinated & Heirloom Seeds

Our open-pollinated (OP) seeds naturally reproduce through wind, insects, water, or self-pollination. When grown in isolation, they produce true-to-type plants year after year.

Among our OP seeds are treasured heirloom varieties — old favorites that have been carefully passed down for generations. While OP plants can be less uniform than hybrids, we run our Open-Pollinated Project to select the most reliable, flavorful, and beautiful strains. Many are also available as certified organic seeds.

Non-GMO: What It Means and Why It Matters

GMO (Genetically Modified Organism) is created when scientists alter a plant’s DNA in a lab — often by inserting genes from completely unrelated species — to achieve certain traits, like pest resistance or herbicide tolerance. This is a far cry from natural plant breeding.

At Shido, we believe gardening should stay as close to nature as possible. All our seeds — whether hybrid, heirloom, organic, or open-pollinated — are Non-GMO. They’re bred using traditional methods that respect natural biodiversity, giving you safe, wholesome seeds that grow into plants just as nature intended.

When you plant Shido Non-GMO seeds, you’re choosing purity, sustainability, and peace of mind — along with a garden full of flavor, color, and beauty.
