How to Grow and Care for Black-Eyed Susans?
When to Plant
Start in early spring, once the frost danger has passed. In warmer zones, late fall works too.
Sunlight and Location
Pick a spot that gets at least 6 hours of direct sun. These plants love the heat and need light to bloom heavily.
Soil and Watering
Use well-draining soil. Sandy, clay, or loam—it doesn’t matter, as long as it drains. Water new plants often; once established, once-a-week watering is enough.

How to Propagate Black-Eyed Susans
You’ve got three easy ways:
- From Seed – Start indoors 6–8 weeks before last frost or direct sow outdoors.
- Division – Every few years, dig up mature clumps and replant.
- Cuttings – Not common but possible with root hormone in early spring.
If you’re seeding, lightly rake them into the soil but don’t bury them deep—they need light to germinate.
