DIRECT SOWING: Sow outdoors as soon as the ground warms up a bit, in late May or about June 10th. in the North. Seed should be sown in groups of 3 - 4 seeds, 18 in/ 46 cm apart. Space seeds about 2 in/5 cm apart in each group, 1/4 in/ 6 mm deep and firm. Cosmos like lots of sun and thrive in well drained, warm sandy soil - without too much moisture. Best used as a tall background or in groups among tall shrubs. Cosmos attract birds to the garden as cosmos seeds ripen in the fall. For good cut flowers, cut freshly opened blooms; place them in ice cold water to prevent wilting. Use plenty of foliage in arrangements.
