Black-eyed Susan seeds can be easily scattered on the ground for planting. In fact, this method can mimic the natural way that these plants self-seed in the wild. However, there are a few things to keep in mind to ensure successful germination and growth.
Firstly, it’s important to choose a suitable location for planting. Black-eyed Susans prefer full sun to partial shade, so select an area in your garden that receives at least six hours of direct sunlight each day. The soil should be well-draining and fertile. If your soil is heavy or compacted, consider amending it with organic matter, such as compost, to improve its texture and nutrient content.
Before scattering the seeds, it can be helpful to prepare the soil by removing any weeds or grass and loosening it with a garden fork or tiller. This will create a favorable environment for the seeds to take root. You can also rake the soil lightly to create a fine, even seedbed.
Next, scatter the black-eyed Susan seeds over the prepared soil. You can do this by hand or use a seed spreader for more even distribution. Aim to sow the seeds at a rate of about 10 to 15 seeds per square foot. Since black-eyed Susan seeds need light to germinate, it’s important not to bury them too deeply. A light covering of soil, about 1/4 inch deep, is sufficient. Alternatively, you can leave the seeds uncovered, as some gardeners find success with this method too.
Water the area gently after sowing the seeds to ensure good seed-to-soil contact. It’s important to keep the soil consistently moist during the germination process, which generally takes around 10 to 20 days. Using a fine mist or sprinkler attachment on your hose can help prevent the seeds from being washed away or disturbed. Once the seedlings emerge, you can reduce watering frequency but continue to provide regular moisture as needed.
As the black-eyed Susan plants grow, it’s important to thin them out if they become overcrowded. This will give the remaining plants enough space to thrive. You can do this by carefully pulling out any excess seedlings, leaving a distance of about 12 to 18 inches between each plant.
In terms of care, black-eyed Susans are generally low-maintenance. They are drought-tolerant once established and do not require frequent fertilization. However, you can provide a balanced, all-purpose organic fertilizer during the growing season if desired. Deadheading faded blooms can also encourage continuous blooming and prevent self-seeding if you prefer to control the spread of the plants.
While it is possible to simply throw black-eyed Susan seeds on the ground, a few guidelines can help ensure successful germination and growth. By selecting a suitable location, preparing the soil, scattering the seeds, and providing adequate moisture, you can enjoy the beauty of these vibrant flowers in your garden.
