Growing guide

From seed to harvest

Sow warm

Start 5–7 weeks ahead, or direct sow after frost once soil passes 60°F; cover lightly.

Pinch and space

Pinch young plants; space 9–12" apart, wider for sturdier stems.

Support tall types

Horizontal netting keeps tall cosmos upright in the wind.

Cut young blooms

Harvest as petals begin to open; keep cutting for flowers all summer.

Growing Information

Transplanting

Start seed in 50-cell trays or similar, barely covered, about 5–7 weeks ahead of your planting-out date. Harden off and move outside once frost is over.

Direct sowing

Wait until frost is past and the soil has warmed past 60°F (16°C), then sow and just cover the seed.

Pinching
