Named for the dark color of their centers, black-eyed Susans are popular flowers in North America. They bloom during the summer and fall months in gorgeous golden and yellow hues. They are territorial flowers, so avoid planting other flowers nearby.
Grow black-eyed Susans in full sunlight
Although they do grow in partial sun, black-eyed Susans thrive in full sunlight.
Provide ample water
Water black-eyed Susans whenever the soil is dry to the touch. They are fairly drought-tolerant, but they grow best when watered as needed. Don't overwater, as muddy soil can cause black-eyed Susans to rot. Water at the base of the plant, and be sure that the roots are sufficiently hydrated.
Maintain the plant to prevent pests
Slugs and aphids are known to attack black-eyed Susans, so be sure to remove any fallen organic plant matter that may encourage them. For serious infestations, it may be necessary to spray the plant with insecticidal soap.
Remove wilted blossoms
As soon as wilted blossoms are spotted, remove them. This encourages long-lasting, healthy blooms all season.
Use fertile soil
Although black-eyed Susans can tolerate conditions that are less than ideal, using fertile soil helps them reach their full potential. Use well-drained soil to prevent overhydration.
