This easy trick will give your wilting hydrangea blooms new life!
I’m back today with a super quick tip that brings a droopy hydrangea back with minimal effort.
I used to hate when I’d buy flowers (or cut them from the yard) and they’d droop within a day or two.
Did you know that hydrangeas are one of the only flowers to draw in moisture from their blooms? Cool huh?
Hydrangeas take in water from everywhere — their stems, petals and leaves.
This little hack allows you to keep cut hydrangeas plump and beautiful for a couple weeks or more!
Here’s what I’m talking about — see the sad bloom on the bottom left?:

Before learning this trick that wilted flower would have been tossed in the trash. Sometimes it drooped within a day of bringing them home or cutting them.
(See some tips to avoid this from the start later in the post!)

Why are my hydrangea blooms wilting?
Hydrangeas have a sticky sap that clogs up their woody stem almost as soon as it’s cut, so it’s important to get them a vase of water right after cutting.
The first thing you’ll want to do to plump them back up is give them a fresh cut at an angle at the end of the stem. (This, along with fresh water, helps prolong the life of cut flowers in general.)
A deep angle gives them more space to drink up plenty of water.
How do you fix wilting hydrangeas?
It’s SO easy. As you can tell from their name — hydrangeas LOVE water. It’s kind of hard to give them too much (at least after they’re cut).
The trick to plumping them back up is to soak the entire flower in cool water.
I fill the sink just enough to immerse them. A large bowl will do the trick as well:
Make sure the hydrangea blooms and stems are both submerged!
Timing is different for every one — some perk up in 20 minutes, some I leave in there for an hour or so.
Here are the same flowers after they’ve soaked up the water: 
Awesome, eh? It’s like magic! 🙂
And each one was been bathed at least once. 🙂
It’s different every time I buy or cut them really — some hydrangeas last for five days without needing a bath, some need it within a day or so.
It’s fun to see the before and afters — wouldn’t it be nice if it was this easy to get everything beautiful again? 🙂
You can do this over and over — you’ll be able to tell when they’re beyond saving because they will stay wilted even after the soak.
A few more hacks for reviving drooping hydrangeas:
- Alum powder — give your stems a fresh cut and dip them into the alum. This prevents the sap from cutting off the water supply. (Find this powder in the spice aisle.)
- Boil water, then let it cool for a few minutes. Cut the stem ends, then dip them in the hot water for 30 seconds. (This prevents the sap from blocking absorption.) Immediately place flowers in room temperature water and then be patient as the water works its way back up the stem.
- Snip the hydrangea stem and replace the water in a vase with HOT water, then put the flowers back in. (This method has not worked as well for me.)
How do you keep hydrangeas from wilting after they are cut?
There are many ways to prevent the wilt from the start! Try these tips to keep them plump longer:
- Hydrangea leaves “steal” water from the blooms, so remove at least any leaves at the bottom of the stem. I like to leave a few near the bloom.
- If you don’t have a packet of flower preservatives, one ground up aspirin works as well!
- Replace the water often, every other day if possible. (Be sure to cut the bottom of the stem each time.)
- Cutting your stems shorter allows the water to reach the blooms easier.
- Mist the hydrangea blooms every day or so — remember they soak water up through their petals!
- Cut a one inch slit at the bottom of the stem to allow for more water absorption.
- Clear soda and even vodka are known to slow wilting as well. Cheers!
These tips will keep your store bought or fresh cut hydrangeas looking beautiful and full for weeks instead of a few days!
