Soil:
Black-eyed Susan plants require average, dry to medium, well-draining soil to grow.
Light:
This perennial tolerates some light shade but flowers best in full sun (> 6 hours of sun).
Water:
Water black-eyed Susan regularly until the plant is established. Once established, it does tolerate some mild drought.
Fertilizing:
Go easy on the fertilizer. Too much will result in weak stems and plants. A side dressing of compost should be all they'll need.
Winterizing:
You can let the last flowers of the season remain on the plants to go to seed and feed the birds.
Maintenance & Pruning:
Deadhead black-eyed Susan to prolong bloom. Divide when clumps become overcrowded. Rudbeckias don't generally die out in the center and don't require frequent division.
