Just a few days ago, I noticed that one of our readers on Facebook asked if she should deadhead her roses after they bloom or not. Unsurprisingly, this seems to be a confusion most new gardeners have.

While we did write back to her separately, I thought I’d address this topic in a detailed article because this concern tends to bother many new rose growers. Let’s dive right into it, shall we?

Deadheading Vs Pruning Roses

When I was young and accompanied my mom in the garden, it never occurred to me that deadheading and pruning were two completely different things.

Whenever my mom said it’s time to prune, I thought we’d be trimming down the messy bits of the plants. And honestly, deadheading looks a lot like that, you’re still cutting something off… But the purpose is completely different!

  • Deadheading: Deadheading involves removing spent flower heads after they’re done blooming. It’s done to encourage more vigorous bloom production and healthy, new growth. 

Many gardeners deadhead their plants throughout the blooming season up until early fall. 

  • Pruning: Pruning requires trimming down large parts of the plant, like stems and whole sections. It restores shape, allows for the removal of weak wood, and promotes better growth later on. 

In terms of timing, heavier pruning is typically done in late winter or early spring. Lighter trims are much more suitable for warmer fall conditions. 

If you’d like a step-by-step walkthrough, here’s a guide on how to deadhead roses for better blooms.

Well, if I’m being honest…it depends!

If you’re working with repeat-bloomers like Hybrid Tea, Floribunda, English roses, or Knock Outs, you can and probably should deadhead spent blooms throughout summer. Doing so will encourage continuous flowering.

That said, you want to pause all deadheading by early fall so that the plant can produce rose hips and prepare for dormancy. If you keep cutting later than that your roses won’t have enough time to form hips before frost!

  • In colder zones (3 to 5), that means stopping by late August;
  • In mid-range zones (6), aim for early September;
  • And in warmer zones (7 to 8), you can usually keep going until late September.

Friendly reminder: Leaving those last blooms to turn into hips doesn’t just help your roses harden off for winter, the hips also feed birds and add beautiful winter interest in the garden.

Many rose varieties like old garden roses, ramblers, and certain climbers only need a light trim after they’re done flowering.

They bloom on old wood, so DO NOT make the mistake of pruning them too hard at once, or you’ll remove next year’s blooms as well.  

Quick note: Some climbers are also repeat-blooming. So, always check your variety before cutting!

Deadheading roses
  • Deadhead your roses in late summer or early fall only if it’s a repeat-blooming variety and you may encourage a few more flowers before frost.
  • Avoid hard pruning for now. Save aggressive trims and cuts for late winter or early springtime.
  • Let the rose hips form on their own in the fall. It will help the plants harden off before peak winter kicks in. 
Deadheading roses
  • Deadhead repeat bloomers in summer all you want, but make sure to take a break in fall.
  • Roses that bloom once must be trimmed lightly after the flowering season. Then, leave them alone! 
  • Avoid cutting back heavily after late summer at all costs.

While it isn’t something I typically recommend, you sure can prune your roses lightly in late summer…only if you feel a serious need for it. It can help tidy up the plant, control plant size, and remove diseased or weak wood.

Still, late summer pruning isn’t ideal, since roses often struggle to recover in the lingering heat, even if it’s on the milder side.

If you’d like to go all-in with your pruning and plan out your cuts, I’ve got a full rose pruning guide you can follow.

To the lovely woman who posted her innocent query on our Facebook, I hope you found your answer. And, I hope all you confused rose growers learned something from this article as well. 

Being an avid rose grower, I know what it’s like when you feel stuck during a certain rose-growing stage and your plant doesn’t seem to be getting any better. However, with a little intention and some focused effort on improving gardening knowledge, things will eventually start to improve. 

Now, it’s time for you to practically implement what you just learned and make the decision to either deadhead or cut back your roses this coming fall!
