Black Eyed Susans are wildflowers that grow well in almost any soil. They are native to North America and can be seen growing alongside roadways across the country. These hearty plants self multiply, so it is necessary to separate them after a few years growth to prevent them from choking each other out and for optimal blooms. Planting should take place in early spring for the best results and blooms.
Seeds that are begun in early spring will yield blooms the first year. These seeds are easy to plant and require very little care. In early spring, work the seeds into the soil using just your finger. This can be completed as soon as the ground is warm and tillable enough to be freely workable. Planting before this can cause little growth or stunned growth as the ground will be too cold for the seed to germinate in the soil.
Seeds that are planted in late summer or early fall will bloom the following spring. Spring planted seeds will bloom by summer’s end. Black Eyed Susans grow in virtually any soil, even dry areas, so the location of planting does not need to be soil specific. They do not require much additional watering or fertilizer, but this added care will produce bigger, more colorful blooms.
Fertilize with Miracle Gro plant food every two weeks, following the manufacturer’s mixing instructions.
After two years of growth, separate some plants from the flower bed and transplant to another area. This will prevent overgrowth and smaller, less lively blooms. To separate the plants, use a pointed blade shovel and dig under the plant, making sure to remove the root ball as well. Carefully remove the root and plant from the soil and plant in another area at the same depth. Water and fertilize as normal. Repeat this process every two years.
