Greetings from Staffordshire! Today, I’m sharing my top tips on deadheading Rudbeckia, a fantastic way to keep these cheery flowers blooming longer.
Quick Answer
To deadhead Rudbeckia, simply remove spent blooms by cutting the stem just above the next set of leaves or lateral bud. This encourages new growth and more blooms.
Why Deadhead Rudbeckia?
Deadheading Rudbeckia, or Black-eyed Susans as they’re often known, is essential to prolonging their flowering season. By removing spent blooms, you’re encouraging the plant to focus its energy on producing new flowers instead of seeds.
- Encourages more blooms and extends flowering period
- Promotes healthier plants by preventing seed formation
- Improves the overall appearance of your garden
When to Deadhead Rudbeckia
In the UK, Rudbeckia typically blooms from late July through to October. Start deadheading as soon as the first flowers fade, which is usually around late August. Continue this process every one to two weeks until the end of the flowering season.
| Month | Activity | Notes |
|---|---|---|
| July | Monitor budding flowers | Prepare for deadheading |
| August | Start deadheading | Cut above leaf nodes |
| September | Continue deadheading | Regular intervals |
| October | Final deadheading | Prepare for winter |
