How to Sow and Plant

Sow Seeds: Directly sow pure white cosmos seeds outdoors after the last frost when soil has warmed up.


Planting Depth: Sow seeds about 1/4 inch deep in well-drained garden soil; lightly cover with soil.


Spacing: Space seeds or seedlings approximately 12–18 inches apart to allow room for growth.

How to Grow

Watering: Keep the soil lightly moist until seeds germinate; once established, cosmos are drought-tolerant and require only moderate watering.


Soil: Prefers well-drained soil; average to poor soil conditions often produce better bloom display than overly rich soil.


Deadheading: Remove spent blossoms regularly to encourage continuous blooming throughout the season.

Tips

Starting seeds indoors 4–6 weeks before the last frost can help get a head start on the blooming season.


Cosmos thrive in sunny spots and are tolerant of drought once established, making them low-maintenance and ideal for busy gardeners.


Avoid over-fertilizing; too much fertilizer can promote foliage growth at the expense of flowers.
