How to Grow Black Eyed Susan from Seed

Choosing the Right Seeds

When it comes to choosing black eyed susan seeds, there are many options available on the market. You can purchase them from local gardening stores, online retailers, or even collect them from your own garden. When selecting seeds, make sure to choose ones that are fresh and plump. Avoid purchasing seeds that are discolored or appear shriveled.

It’s also important to consider the variety of black eyed susans you want to grow. There are different types with varying sizes and colors. Some popular varieties include ‘Goldstrum’, ‘Cherokee Sunset’, and ‘Irish Eyes’. Research about these varieties and their specific growing requirements before making a decision.

Planting Time

The best time to plant black eyed susan seeds is in the spring when the soil has warmed up and there is no longer a risk of frost. This usually falls between March and May, depending on your location. If you’re planting from seedlings, it’s best to do so in early spring or late summer when the weather is cooler.

Planting Process

To plant black eyed susan seeds, follow these simple steps:

  1. Choose a sunny spot in your garden with well-drained soil.
  2. Loosen up the soil by digging at least 6 inches deep.
  3. Mix in compost or organic matter to enrich the soil.
  4. Scatter the seeds over the prepared area and lightly cover them with a thin layer of soil.
  5. Water gently but thoroughly to keep the soil moist.
  6. Keep an eye on your seedlings and water regularly, but be careful not to overwater.
  7. Once the seedlings have established themselves, thin them out to allow for proper spacing, typically 12-18 inches apart.
  8. Black eyed susans are fairly low maintenance plants and do not require much fertilization. However, if you choose to fertilize, use a balanced fertilizer every few weeks.
  9. As the plants grow taller, it may be necessary to provide support with stakes or trellises.
  10. Enjoy the beautiful blooms of your black eyed susans throughout the summer and early fall.

Step-by-Step Guide on How to Grow Black Eyed Susan from Seed 

Step 1: Select a Suitable Location 

The first step in growing black-eyed susans from seed is choosing the right location. These flowers thrive in full sun, which means they require at least six hours of direct sunlight daily. While partial shade is acceptable, too much shade may result in weaker plants and fewer blooms. Before planting, take note of the areas in your yard that receive consistent sunlight, and plan your garden layout accordingly.

Step 2: Prepare the Soil

Black-eyed susans are remarkably adaptable and can grow in various soil types, but they perform best in well-draining soil with a slightly acidic to neutral pH, ranging from 6.0 to 7.5. Before planting, remove any debris, such as weeds or rocks, from the soil. Loosen the top layer to a depth of at least six inches, allowing for better water penetration and root growth. Amending the soil with compost or organic matter can improve fertility and enhance plant vigor, particularly if you’re working with sandy or clay-heavy soils. 

Step 3: Start Seed Germination 

To begin germination, black-eyed susan seeds can be sown directly in the ground or started indoors. Indoors, sow seeds in small pots or seed trays filled with a quality seed-starting mix about six to eight weeks before the last expected frost. Press the seeds lightly into the soil’s surface without covering them too much, as they require light exposure to germinate. Water gently to keep the soil consistently moist while avoiding overwatering, which can lead to mold or damping-off disease. Keep the planted seeds in a warm location with temperatures around 68–72°F. 

Step 4: Thin and Transplant Seedlings 

Once seedlings have emerged and developed their first set of true leaves, you’ll need to thin them out so each plant has enough space to thrive. If you started seeds indoors, transplant the seedlings outdoors once the danger of frost has passed. Prepare holes in your garden area spaced roughly twelve to eighteen inches apart, giving the mature plants plenty of room to grow and spread. Carefully remove the seedlings from their containers and place them into the prepared holes, ensuring the root ball remains intact. Water the seedlings immediately after transplanting to reduce transplant shock. 

Step 5: Establish a Watering Routine 

Proper watering is essential during the early stages of growing black-eyed susans from seed. When first establishing the plants, water regularly to keep the soil consistently moist but not soggy. Once the plants are well-established, they become relatively drought-tolerant and require less frequent watering. Ensure the soil dries out slightly between watering sessions to prevent fungal issues, but avoid letting it become bone-dry for extended periods. 

Step 6: Encourage Growth with Fertilizer 

Although black-eyed susans are hardy and low-maintenance, they can benefit from an occasional boost of nutrients during their growth cycles. Use a balanced, slow-release fertilizer once during the growing season to provide essential nutrients. Applying organic compost to the base of the plants is another excellent way to encourage robust growth without the risk of chemical buildup. Be careful not to over-fertilize, as excessive nutrients can lead to lush foliage at the expense of blooms.

Step 7: Provide Support If Necessary 

Depending on the variety of black-eyed susan you are growing, some plants may require additional support, especially in windy areas. Taller varieties may need to be staked to prevent them from toppling over under the weight of their blooms. Secure the plants gently to a stake using garden ties or soft string, being careful not to damage the stems. Providing support ensures your flowers remain upright and healthy throughout the growing season. 

Step 8: Prune and Deadhead Regularly 

To promote continuous blooming, remove spent blooms by pinching them off or cutting them back to a lower set of leaves. This process, known as deadheading, redirects the plant’s energy from seed production to creating new flowers. Additionally, pruning leggy or damaged stems helps maintain the plant’s shape and overall health. Regular maintenance throughout the season contributes to a vibrant and thriving garden. 

Step 9: Prepare for Seed Harvest or Overwintering 

Towards the end of the growing season, allow some flowers to remain on the plant to form seed heads if you’d like to collect seeds for future planting. Once the seed heads have dried, you can carefully remove and store the seeds in a cool, dry place. If you prefer to propagate new plants naturally, simply allow the seeds to fall to the ground. For overwintering perennials or biennials, apply a layer of mulch around the plants to protect them from harsh winter conditions and prepare them for the next growth cycle.

Additional Tips for Successful Flower Gardening

In addition to the basic guidelines mentioned above, there are a few more tips that can help you achieve successful flower gardening:

  1. Choose the right location: Before planting any flowers, it is important to select the right location in your garden. Most flowering plants require at least 6 hours of sunlight per day, so make sure the area receives enough sun exposure. Also, consider factors like soil quality and water drainage when selecting a spot for your flower garden.
  2. Plan your garden layout: It is always helpful to plan out your garden layout beforehand. This will not only ensure that all your desired plants fit into the space but also create an aesthetically pleasing design. Consider the height, color, and blooming time of each plant to create a well-balanced and visually appealing garden.
  3. Choose a variety of flowers: To make your flower garden more interesting and visually appealing, it is important to choose a variety of flowers. Mix different colors, textures, and sizes to create a dynamic and diverse garden. You can also consider incorporating different types of plants such as annuals, perennials, bulbs, shrubs, and vines for added interest.
  4. Consider the blooming season: When selecting flowers for your garden, it is important to consider their blooming season. This will ensure that you have blooms all year round in your garden. Choose a mix of flowers that bloom in spring, summer, and fall to keep your garden vibrant and colorful throughout the seasons. Additionally, incorporating evergreen plants can add some greenery and structure to your garden during the winter months.
  5. Add some fragrance: A beautiful garden not only appeals visually but also engages our sense of smell. Consider adding some fragrant flowers such as lavender, roses, jasmine, or lilac to make your garden a sensory experience. You can also plant herbs like mint, thyme, or basil for a delightful aroma while also providing fresh ingredients for cooking.
