Disease can also affect Rudbeckia. The most common diseases are powdery mildew and rust. Ensure proper spacing between plants to improve air circulation. Water the base of the plant to keep foliage dry. Use a fungicide if diseases appear.
| Maintenance Task | Frequency | Tools Needed |
|---|---|---|
| Pruning | Once a year | Pruning shears |
| Deadheading | Weekly | Scissors or fingers |
| Pest Control | As needed | Insecticidal soap, neem oil, bait traps |

Seasonal Care
Seasonal care is crucial for growing healthy Rudbeckia, also known as Black-Eyed Susan. Understanding the specific needs of these plants in different seasons ensures they thrive year-round.
Spring And Summer Care
Spring is the time to plant Rudbeckia seeds or young plants. Ensure the soil is well-draining and rich in organic matter. Space plants 18-24 inches apart to allow proper air circulation.
- Watering: Keep the soil consistently moist but not waterlogged. Water deeply once a week.
- Fertilizing: Apply a balanced, slow-release fertilizer in early spring. This promotes healthy growth.
- Mulching: Add a 2-3 inch layer of mulch around the plants. This helps retain moisture and suppress weeds.
- Deadheading: Remove spent flowers to encourage continuous blooming. This also prevents seed formation.
During summer, continue to water and deadhead regularly. Monitor for pests such as aphids and treat them promptly with insecticidal soap.
Fall And Winter Care
In fall, prepare Rudbeckia for the colder months. Cut back the stems to about 6 inches above ground level. This prevents disease and encourages new growth in spring.
- Mulching: Apply a thicker layer of mulch (4-6 inches) around the base. This insulates the roots from freezing temperatures.
- Watering: Reduce watering frequency as the plant enters dormancy. Ensure soil is not completely dry.
- Protection: Cover plants with a frost cloth if frost is expected. This provides extra protection.
In winter, minimal care is needed. Just monitor the plants and ensure they are protected from extreme cold.
