Fall Cutback for Black-Eyed Susans: Timing Matters

Black-eyed Susans (Rudbeckia) still green in fall? Wait.

• Still blooming: Let them finish. Cut after first frost or when stems brown.
• Done blooming: Cut to 4–6 inches above ground now.
• Disposal: Remove cuttings — don't compost if any disease present.

Leaving seed heads feeds birds but encourages prolific self-seeding. If you want volunteers, leave a few; otherwise, clean cut prevents a weedy patch next spring.

Rudbeckia is tough — it returns reliably from crown and roots. A clean bed now means a stronger start in April.
