When to Plant Sensation Cosmos Mix Seeds
Sow outdoors after frost. In short-season climates, start indoors about four weeks before planting out, then harden off.

Choose full sun and free-draining soil. Avoid heavy feeding: rich soil can produce more foliage than flowers.

Clear weeds and rake the bed to a fine surface.
Sow shallowly, following the packet depth; keep soil lightly moist until emergence.
Thin to provide room for the tall, airy stems.
How to Harvest Sensation Cosmos Mix
Cut long stems when the flowers have just opened and strip any foliage that would sit below the water line. Regular picking and removal of spent blooms can keep plants flowering longer.
How to Care for Sensation Cosmos Mix
Water during establishment and extended drought. Remove faded blooms or cut stems regularly; stake only where wind or crowding makes stems lean.
