Black-eyed Susan plants require average, dry to medium, well-draining soil to grow.


This perennial tolerates some light shade but flowers best in full sun (> 6 hours of sun).


Water black-eyed Susan regularly until the plant is established. Once established, it does tolerate some mild drought.


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.


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.
