Description

A moderately moist environment is all the seeds require; there’s no need for excessive watering or fertilizer during germination. Typically, they will sprout within 3 to 4 weeks.

Plant sunflower seeds directly into the garden or outdoor containers after the risk of spring frost has passed, typically when soils have warmed to at least 50°F (10°C).

In the northern half of the U.S. and Canada, this period generally spans from April to mid-June. In the South, planting is typically done in mid-March or early April.

Sunflowers do not like their roots disturbed, so direct sowing is preferable over transplanting.

Planting Sunflower Seeds

Plant sunflowers 1 to 1½ inches deep and space them about 6 inches apart after the soil has warmed thoroughly. Optionally, you can sow multiple seeds and thin them to the strongest contenders once the plants reach six inches tall.

Ensure ample space, especially for low-growing varieties that spread out. Make rows approximately 30 inches apart. For very compact varieties, you can plant them closer together.

A light application of fertilizer mixed in during planting will promote strong root growth, helping the plants withstand windy conditions.

To enjoy continuous blooms, try planting sunflowers in staggered intervals over 5 to 6 weeks.

If birds are pecking around for seeds, cover the planted area with netting until the seeds germinate.
