To plant black-eyed Susan seeds, choose a suitable location and prepare the soil. Next, sow the seeds and lightly water them. Plant black-eyed Susan seeds directly outdoors or indoors in pots or seed beds.Continue Reading
For early blossoms, plant the seeds indoors about six to eight weeks before the anticipated last frost. Otherwise, plant them directly outdoors once the soil temperature has reached 70 degrees Fahrenheit.
Plant the seeds in a sunny part of the garden where the soil drains well. Keep indoor plants close to a window but not in direct sunlight.
Use a shovel to loosen the soil, and then smooth it with a rake. Purge weeds and other vegetation from the planting area so the flowers do not need to compete for nutrients. Do not add compost or manure because black-eyed Susan plants do not thrive in over-rich soil. Once the soil is smooth, firm it by walking on it or using a lawn roller.
Sow the black-eyed Susan seeds over the seed bed at a ratio of about a teaspoon of seeds for every 100 square feet. Afterwards, cover the seeds with 1/16 inch of soil. Pack the soil down gently. Transplant seeds started indoors once the danger of frost is over.
Water the seed bed gently so the seeds don't wash away. Set the hose sprinkler on a mist setting.
