Black-Eyed Susans are incredibly easy-care flowers, and they're native to the United States. Since these unfussy perennials are used to American climates, they don't need much help from the gardener! Just make sure to plant your Black-Eyed Susans in a sunny location with well-draining soil, and they'll perform wonderfully. Unless you experience a long dry spell, you don't need to water or fertilize your Black-Eyed Susans. They can handle dry weather and low-quality soil, especially once they've been established in a location for a growing season. For the first year, check your Black-Eyed Susans regularly to make sure they don't get too dry. If you live in a zone with bitterly cold winters, mulch the plants after the first growing season to insulate them. After they're well settled, these plants are drought and heat tolerant, and very hardy! The only care regularly needed each season for Black-Eyed Susans is deadheading. Remove the spent flowers after they fade, to keep the plants looking vibrant. Then, divide the plant every three or four years to keep it from becoming overcrowded. Division and deadheading can both help prevent excessive spreading, too, so that you don't end up with too many Black-Eyed Susans. If you want to attract birds to your garden, however, leave a few flower heads on your plants in the fall, and the birds will take care of cleanup.
