Growing guide

From seed to harvest

Sow after frost

3–4 seeds per spot, 1/2" deep; thin to one.

Avoid root disturbance

Sow in the final pot if starting indoors.

Give them room

8–12" so leaves do not touch.

Cut as they open

Fully open for drying.

Growing Information

Days to germination

About 1–2 weeks at 70–75°F (21–24°C).

Direct sowing

The best method. After the last frost, sow 3–4 seeds per spot, 1/2" deep, and thin to one plant at the first true leaves.

Starting indoors

Sunflowers dislike root disturbance, so sow straight into the final container 3–4 weeks before planting out: one seed per 6" pot or three per gallon pot. For beds, plant out once seedlings have 3–4 true leaves.

Growing on

About 70–80°F (21–27°C) by day and 50–60°F (10–16°C) at night. Warmer conditions make plants stretch; cooler ones keep them shorter.

Light

Full sun.

Soil

Light, free-draining soil of low to moderate fertility.

Plant spacing

8–12", far enough that leaves do not touch; crowded plants grow taller with weaker stems.

Hardiness

Annual.

Harvest

For fresh use, cut as the flowers start to open. For drying, wait until they are fully open, then hang them or use silica gel.

Uses

Containers and mass plantings.

Packet

50 seeds.

Seeds per oz.

About 1,140 on average.
