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.
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.

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.
