How to Keep Cut Hydrangeas Alive in a Vase

Hydrangeas are popular flowers that can add a beautiful touch to any room. However, they can be tricky to keep alive in a vase. I’ve been growing and cutting hydrangeas for many years and they don’t always do well in a vase without a little help. So follow these simple tips and tricks to help keep fresh-cut hydrangeas from wilting in a bouquet.

Why Are My Fresh Cut Hydrangeas Wilting?

It’s important to understand why fresh cut hydrangeas wilt when they are in a vase. And the reason is, they self-heal from the initial cut. Because cut stems start to form a substance over the wound to heal itself, water has trouble reaching the blooms.

When the flowers don’t get enough water, they start drooping. Luckily, there are two easy fixes for this. Because with proper hydrangea care, the flowers can last a long time in an arrangement.

There are two easy ways to keep hydrangeas alive that will keep those fresh-cut flowers looking gorgeous for weeks!

How to Keep Fresh Cut Hydrangeas from Wilting

Whether you cut hydrangeas from your flower garden or pick them up from the grocery store, there are two easy methods to keep cut hydrangeas from wilting. And the best part? Minimal supplies are required.

Supplies Needed for Keeping Fresh-Cut Hydrangeas From Wilting

  • Pruners
  • Container filled with fresh water for the initial fresh cuts
  • A second container filled with fresh water to display the arrangement
  • Alum Spice (if using the alum method)
  • Small pot filled with boiling hot water (if using the hot water method only)

Keeping Hydrangeas Fresh Using the Hot Water Method

To me, this is the easier way to do it because you don’t need anything else besides sharp pruners and boiling hot water. Here’s how to do it.

Hot Water Method Directions

  • After the initial cuts are made, boil water.
  • Have a second container of room-temperature water ready to hold the arrangement.
  • Cut hydrangea stems again on an angle to the desired length of the arrangement.
  • Optional: some like to smash the bottom of stems so it takes in more water. (I’ve never done this but I’ve heard it works).
  • Stand hydrangea stems in hot water for 30 seconds.
  • Immediately drop into room temperature water.
  • Arrange flowers accordingly.

And that’s it! Super easy right? Ok, so that’s the hot water method. Here’s how to do the alum method.

How to Keep Fresh Cut Hydrangeas from Drooping Using Alum Powder Method

Have you ever heard or used alum before? Alum powder is a spice that is used for pickling and canning. But did you know that it can also be used to help keep hydrangeas from wilting?

Alum Spice Method Directions

  • After making the initial cuts from the plant, immediately drop stems in freshwater.
  • Get a second container with fresh water ready and grab the alum spice.
  • While arranging the blooms, re-cut stems on an angle to the desired length of the arrangement.
  • Dip the bottom 1/2 inch of the stem into the alum.
  • Drop into the second container
  • Arrange the flowers.

Emergency Care: How Do You Save Cut Hydrangeas After They Wilt in a Vase

If your fresh cut flowers started wilting in an arrangement, I got you! All is not lost because there’s a trick to reviving hydrangeas after they wilt. Here’s what you need to know.

  • If the arrangement’s water is more than a day old, dump it and add fresh water before reviving it.
  • Soak the blooms for several hours. I do this in the kitchen sink.
  • Re-cut all the stems at an angle.
  • Choose and follow one of the above methods to finish reviving the blooms.
  • Note: if the arrangement is much older, blooms may be more difficult to revive. But give it a shot!

Don’t these fresh-cut hydrangeas look so beautiful? I love how they look in this pretty vintage container too.

Fresh Cut Hydrangea Care FAQs

If you cut your hydrangeas from your garden, here are a few FAQs with answers that will help you care for the flowers.

Do You Put Cut Hydrangeas in the Water Immediately After Cutting?

Yes. It’s really important to get fresh cut hydrangeas in water immediately after cutting them so they continue to take in water. Dropping cut hydrangeas immediately into water after cutting will help keep them from wilting. So when you head out to the garden to cut hydrangea flowers, make sure you bring a large bucket of water with you.

Note: As soon as you cut, drop the hydrangea stem in that bucket of water to help keep them fresh and prevent the droop.

What Is the Best Time of Day to Cut Hydrangeas?

Believe it or not, the time of day when you cut hydrangeas is equally as important as putting them in water after cutting them to help keep them fresher for longer in a vase. The best time of day to cut hydrangeas is in the morning when the weather is much cooler.

Now that doesn’t mean you can’t cut later in the day, because you can if you had to. But it’s a good idea to avoid cutting in the heat of the day. The flowers last longer when cut in the morning, so I recommend aiming for that timeframe.

How Long Do Cut Hydrangeas Last Once Cut?

I’ve read 2-5 days, but from my experience, they last much longer than that. When I cut hydrangea flowers in the morning and used one of these two methods, they lasted over a week.

I even tested out both ways to see if one lasted longer. From my experiment, the alum method for fresh cut hydrangea care helped the flowers last a little bit longer than the hot water method.

  2. Do you have any tips for drying hydrangeas? I find some types dry naturally even when in water, but the traditional hydrangeas don’t seem to be easy to dry.

    1. Hi Teresa! Its funny you ask! I am sharing a blog post on it tomorrow!! Are you signed up for my newsletter? If so, it will go right to your inbox!

  4. Hi Stacy – I will order the alum powder today. Thank you so much for a great tip.
    Love hydrangeas. I have probably propagated over 50 of them.

  5. Thank you so much for taking the time to post these helpful tips. I used the hot water method, and No Droop! Even after 2 days! Very happy to enjoy my hydrangea blossoms inside!

  6. I use the Alum trick and it works well.

    Our Limelights are slowly expanding. It makes my heart so happy.

    I love them !

  7. Hi…is that Hoosier alum powder granulated? I looked up the one you show here and it appears to be granulated, not an actual powder. Just want to make sure I order the right one.

  8. Hi…is that Hoosier alum powder granulated? I looked up the one you show here and it appears to be granulated, not an actual powder. Just want to make sure I order the right one.

    1. It is similar to a powder – you can probably find it in your spice aisle at the grocery store too.

  9. Your garden has the touch of a lady who loves gardening. So beautiful.
    When I go out of town I have a lady come every day to check my small garden.
    She waters what needs watering and with the horribly hot weather we have had in Va. Beach, it’s a daily need.
    I don’t know if you know anyone who could check on your garden when you are away. Maybe not just to water but tie up what needs tying up.
    Yes, alum is in the spice aisle and could also be in the canning materials aisle.
    Just love your blog.

  11. Hi Stacy, I’ve just tried the alum method. It worked great! My concern, after placing the alum dipped Hydrangea, into a CLEAR glass vase of fresh water, that water became milky. Didn’t like that look. Can I remove the blooms after a certain time period, and place them in another vase of fresh water without them drooping? Your thoughts?

    1. Hi Donna! I’m glad you found it helpful. If you do that, I’d do a fresh cut and dip them in the alum again.

  12. Stacy, I have hydrangea envy….can’t grow them here but hope to have some plants up at our mountain cabin next summer. Love all your pics!

  13. I just planted some Annebelle’s and a Nantucket Blue. So happy to know the tricks! Thanks for sharing!
