Pruning everblooming hydrangeas is simpler than you might think, and getting it right ensures a spectacular show of flowers all season long.
If you’ve been wondering how to prune everblooming hydrangeas without accidentally cutting off this year’s blooms, you’ve come to the right place.
The secret lies in understanding that these special hydrangeas bloom on both old wood and new wood, so your pruning method needs to be a bit more forgiving.
In this post, we’ll break down exactly how to prune everblooming hydrangeas, when to grab your shears, and the common mistakes that even seasoned gardeners make.
Let’s dig in and make your hydrangeas the envy of the neighborhood.
How to Prune Everblooming Hydrangeas: The Basic Rules
The first thing to know about how to prune everblooming hydrangeas is that a light touch works best.
Unlike traditional mophead hydrangeas that bloom only on old wood, everblooming varieties like Endless Summer and Let’s Dance produce flowers on both old and new growth.
This means you can prune everblooming hydrangeas more freely, but you still want to avoid heavy cutting that removes all the older stems.
The goal is to shape the plant, remove dead wood, and encourage fresh growth without sacrificing the early flush of flowers that comes from last year’s stems.
So, when you’re learning how to prune everblooming hydrangeas, remember this golden rule: cut less, not more.
1. Identify the Stem Types Before You Cut
Before you even pick up your pruners, take a good look at your plant’s structure.
You’ll see thicker, woodier stems that are from last year, and these are your old wood that will give you those early blooms.
You’ll also see thinner, greener stems that grew this season, which are your new wood and will bloom later in the summer.
When you prune everblooming hydrangeas, you want to keep a healthy mix of both stem types on the plant.
If you cut away all the old wood, you’ll lose the first wave of flowers, so be selective and gentle.
2. Time Your Pruning for Maximum Blooms
Timing is everything when it comes to how to prune everblooming hydrangeas successfully.
The best time to prune everblooming hydrangeas is in late winter or very early spring, just as the buds begin to swell.
Pruning at this time allows you to see which stems survived the winter and which ones are dead or damaged.
You can also do a light summer pruning right after the first big flush of flowers fades, which encourages another round of blooms on the new growth.
Avoid pruning everblooming hydrangeas in late fall, as this can stimulate tender new growth that will be killed by frost.
3. Use the Right Tools for Clean Cuts
To prune everblooming hydrangeas properly, you’ll need a pair of sharp bypass pruners for stems under half an inch thick.
For thicker, woodier branches, a pair of loppers will give you the leverage you need without crushing the stem.
Always make your cuts at a 45-degree angle, just above a healthy bud node, to promote strong new growth.
Clean, sharp tools are essential when you prune everblooming hydrangeas because ragged cuts invite disease and pests.
When to Prune Everblooming Hydrangeas for Two Bloom Cycles
If you really want to master how to prune everblooming hydrangeas for repeat blooming, you need to think in two phases.
The first pruning window is in early spring, and this is your main structural prune where you remove dead, damaged, or crossing branches.
The second window is in midsummer, right after the first wave of flowers starts to fade, and this is where you can shape the plant again.
4. Early Spring: The Cleanup Prune
In early spring, your main job is to clean up the plant and remove anything that didn’t make it through winter.
Look for stems that are brown, brittle, or hollow, and cut them all the way back to the base of the plant.
For the healthy old wood, you can trim back the tips by about one-third to encourage bushier growth.
This is the perfect time to prune everblooming hydrangeas because you’re not sacrificing any of the coming season’s buds.
5. Midsummer: The Shaping Prune
After the first flush of blooms fades in early summer, you can prune everblooming hydrangeas again to tidy them up.
Cut the spent flower heads off just above a pair of healthy leaves, and this will prompt the plant to send out new growth.
That new growth will then produce a second round of flowers by late summer or early fall.
When you prune everblooming hydrangeas in midsummer, you can also remove any weak or spindly stems that are taking energy away from the main structure.
Common Mistakes When You Prune Everblooming Hydrangeas
Even with the best intentions, many gardeners make a few classic errors when they prune everblooming hydrangeas.
The biggest mistake is pruning too late in the spring, which cuts off the developing flower buds on the old wood.
Another common issue is shearing the plant into a ball shape, which removes all the natural arching form and reduces flowering.
6. Don’t Cut Everything Back to the Ground
It’s tempting to give your hydrangeas a hard cutback to rejuvenate them, but this is a huge no-no with everblooming types.
If you cut everything to the ground, you’ll get lots of new foliage but very few early flowers.
Instead, practice renewal pruning, which means removing only about one-third of the oldest stems each year.
This way, you’re always maintaining a mix of old wood for early blooms and new wood for late-season flowers.
7. Avoid Pruning in Extreme Heat or Drought
Your hydrangeas are already stressed by heat and lack of water, so adding pruning stress is not a good idea.
When you prune everblooming hydrangeas during a heatwave, you can cause the plant to drop leaves and go into shock.
Always water your plant deeply a day or two before you plan to prune, and try to do your cuts in the cooler morning hours.
Healthy, hydrated plants recover much faster, so this little step makes a big difference.
So, How Do You Prune Everblooming Hydrangeas?
You prune everblooming hydrangeas with a light touch, sharp tools, and a solid understanding of their two-wood system.
In early spring, you clean out dead wood and lightly shape the plant, and in midsummer, you deadhead and encourage a second bloom set.
You never cut everything to the ground, and you never prune in the fall or during a hot, dry spell.
By following these simple steps, you’ll enjoy waves of gorgeous flowers from late spring all the way into autumn.
Now that you know how to prune everblooming hydrangeas, grab your pruners and give your shrubs the care they deserve.
Your future self will thank you when you’re staring at a sea of vibrant blue, pink, and purple blooms.
