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 1-2 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:

Starting Indoors: For earlier Sunflower blooms, you may optionally 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 temperatures are consistently above 60F. 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 after all danger of frost has passed in spring and soil temperatures reach at least 60F. Fall planting is not recommended unless planting outdoors in environments with mild, frost-free winters for a head start in the following spring, or planting indoors with supplemental grow lights.

To plant, make holes 1-2 inches deep and spaced 4-6 inches apart down the rows of raised beds.In small plots, flower seeds may be scattered then covered with soil. Once seedlings emerge, plants can separated and spaced 4-6 inches apart to allow room for mature plants to spread and prevent overcrowding. Water after planting.

Planting Depth:	1-2 inches
Within-Row Spacing:	4-6 inches
Between-Row Spacing:	1-2 feet

Care During the Season:

Sunflowers are relatively drought-tolerant once established and require minimal care but thrive with full sun for at least 6-8 hours daily and regular watering, especially during dry spells. Water deeply at the base of sunflower plants. Fertilization is usually unnecessary if the soil is already nutrient-rich, but for poor soil, a balanced fertilizer at planting and once again midway through the growing season can help promote healthy growth. While sunflowers are hardy, larger plants may need staking to prevent them from falling over in windy conditions. To harvest, once the sunflowers bloom and the flower heads mature, leave the seeds to ripen fully while still attached to the plant. Harvest the flower heads when the petals start to dry and the seeds appear plump and firm, cutting the head with a portion of the stem. Properly dried flower heads can be stored for seed saving or enjoyed as beautiful dried arrangements.
