🌼 Black‑Eyed Susan (Rudbeckia hirta)
Zones: USDA 3–9 • Heat Zones 8–10
Light
Full sun (6–8 hours). Tolerates partial sun but blooms best in strong light.
Water
Water deeply when the top 1–2 inches of soil are dry. Avoid keeping soil constantly wet. Established plants are moderately drought‑tolerant.
Soil
Well‑draining potting mix. Avoid heavy, manure‑rich soils. Ideal for containers and Florida conditions.
Fertilizer
Feed lightly once a month during the growing season with a balanced, slow‑release fertilizer. Too much fertilizer reduces blooms.

Pruning & Deadheading
Remove spent blooms to encourage continuous flowering. Trim back leggy stems to maintain shape.
Pests & Issues
Generally low‑maintenance. Watch for aphids or leaf spot; treat early with insecticidal soap or neem if needed.
Blooming
Blooms spring through fall in Florida. Attracts butterflies, bees, and pollinators.
Spacing
If planting multiples, allow airflow between plants to prevent mildew.
