How to Plant Sunflowers from Seed

When to Plant Seeds

  • Outdoors (recommended): Sow seeds after the danger of frost has passed and soil temperature is at least 60°F.
  • Successive Planting: To extend bloom time, plant seeds every 2-3 weeks through mid-summer.

Seed Preparation

  • No special preparation is needed, but soaking seeds in water for a few hours before planting can speed up germination.

Sowing Seeds Outdoors

  1. Loosen the soil to a depth of 12 inches.
  2. Sow seeds 1 inch deep and 6-12 inches apart, depending on variety size.
  3. Water thoroughly and keep the soil moist until seedlings emerge (7-10 days).

Transplanting Seedlings

  • If started indoors, harden off seedlings before transplanting.
  • Space them according to the mature plant size (1-3 feet apart for large varieties).

Pro Tip

Sunflower seeds are ready for harvesting when the back of the flower head turns yellow to brown, and either the seeds appear plump and firm or the petals dry out and fall off. To harvest, cut the flower head with 6 inches of stem attached and hang it upside down in a dry, ventilated area. Once the head is fully dry, rub the seeds out by hand and store them in an airtight container in a cool, dry place.

Getting to know your Sunflower

Sunflowers are annual plants that complete their lifecycle in one growing season. They can grow anywhere from 1 to 12 feet tall, depending on the variety. They have thick, sturdy stems that support their large flower heads. Leaves are broad and heart-shaped, with a rough texture. Sunflowers exhibit heliotropism, meaning young plants turn to face the sun. Sunflowers bloom in late summer and early fall. Seeds are typically harvested in late summer or early autumn when the flower heads mature.
