Planting Instructions:

Soil Preparation:

Choose an area with heavy, well-draining soil that receives at least 6 hours of sunlight each day. Remove weeds, large rocks, and litter from the planting area. Leave small weeds and dead grass, they will enrich the soil when turned under. Spade or till the soil 6-8 inches deep. Loosening the soil will help the plant establish strong roots. If the soil is heavy or clay-like, mix in some sand or compost to improve drainage. Optionally, form rows of soil beds 4-6 inches high and at least 2 feet apart. This formation of ridges will help with drainage, ensure good airflow, and make harvesting for cut flowers easier. Lay down 1/2"-3/4" peat moss, sawdust, or potting soil, the soil surface. This layer is beneficial for flower seeds because it can the improve the germination environment and prevent soil crusting.

Planting:

Cosmos prefer hot climates, growing best in 65F-85F temperatures. For earlier Cosmos blooms, you may start planting indoors in containers 4-6 weeks before the last expected frost date in Spring, keeping seedlings at least 65F. Harden off then transplant seedlings outdoors in a sunny location when the soil warms to at least 65F. To transplant seedlings, prepare a transplant hole outdoors in a sunny location. Remove the plants carefully from the pots or flats and set them in the transplant holes, burying some of the stem in the ground. Pack the soil loosely around the plant and leave a slightly sunken area around each plant to hold water. Water the plants after transplanting.

Directly Sowing: If directly sowing outdoors, plant Cosmos after all danger of frost has passed in Spring and the soil warms to at least 65F. For fall planting in cold climates, sow in mid-summer at the latest. To plant, make holes 1/4 inch deep and spaced 1-2 feet apart down the rows of raised beds. Plant 2-3 seeds per hole, then cover thinly with soil. In small plots, flower seeds may be scattered and gently watered in. Once seedlings emerge, plants can separated and spaced 1-2 feet apart to allow room for mature plants to spread and prevent overcrowding. Water after planting.

Planting Depth:	1/4 inch
Within-Row Spacing:	1-2 feet
Between-Row Spacing:	2-3 feet

Care During the Season:

Once established, Cosmos are hardy, drought-tolerant plants that require minimal maintenance. Water deeply during prolonged dry spells. Fertilization is usually not needed. Cut back plants after they stop blooming or let them reseed naturally for next season.
