To grow and harvest Black-Eyed Susan (Rudbeckia) from seeds, you will need the following materials: well-draining soil, a pot or garden bed, Black-Eyed Susan seeds, compost or organic fertilizer (optional), water, and gardening tools.

Here are the steps to grow and harvest Black-Eyed Susan:

Soil preparation: Black-Eyed Susan thrives in well-draining soil. Prepare the soil by removing any weeds, rocks, or debris and loosen it to a depth of a few inches. Adding compost or organic fertilizer can help improve soil fertility.
Sow the seeds: Scatter the Black-Eyed Susan seeds on the soil surface and lightly press them into the soil, as they require light to germinate. Alternatively, you can sow them in rows, spacing them about 6-12 inches apart.

Sunlight and temperature: Black-Eyed Susan prefers full sun, although it can tolerate partial shade. Ensure that the plants receive at least 6 hours of direct sunlight per day for optimal growth. They are adaptable to a wide range of temperatures.
Maintenance: As the seedlings grow, thin them out to provide enough space for each plant to develop. Remove weeds that compete for nutrients and water. You can also provide support, such as stakes or cages, for taller varieties that may need extra stability.
Harvesting: Black-Eyed Susan is primarily grown for ornamental purposes and not typically harvested for consumption. However, you can cut the flowers for floral arrangements or leave them on the plant to enjoy their beauty in the garden.
