How To Make Cut Hydrangeas Last Longer

Cut hydrangeas are one of the most beautiful flowers to bring indoors, but they can wilt quickly if they are not prepared the right way. With a few simple steps, including removing the lower leaves, cutting the stems at an angle, and dipping them in alum, hydrangeas can stay fresh and beautiful for a week or longer.

These tips work for both grocery store hydrangeas and mature blooms cut from the garden. Whether you arrange them in a favorite pitcher or place a few stems in a simple vase, hydrangeas add a fresh and timeless touch to any room.

Remove The Lower Leaves

The first thing to do is snip off most of the leaves below the bloom. Leaves are moisture suckers, and they muddy the water in your container. It’s fine to leave a few leaves for interest, but make sure they are as close to the bloom as possible.

Cut The Stems At An Angle

• In order to get the maximum amount of water to the bloom, the stems need a sharp, long cut.
• First, decide on your desired length for the stems.
• Using a knife or very sharp scissors, cut the stem at an angle (not a straight cut) that is as long as you can make it.
• If you use a knife, hold the stem down firmly with a few fingers to make the diagonal cut easier. It’s important to have a sharp knife because hydrangea stems are quite tough.
• I use these shears, and can achieve a clean, angled cut. This method works just as well on garden hydrangeas as long as they are mature. It’s hard to get a good slice on a thin, young hydrangea stem.

Dip the Stems in Alum Powder

The easiest thing to do is to pick up a jar of alum at the grocery store (in the spice aisle) and keep it on hand for your cut hydrangeas. As you cut the stems, dip them quickly into the alum jar, and then plunge them into a container of room temperature water. Once you dip a stem in the jar, clearly you can’t use it for anything else!

Change the water after a few days

After you have enjoyed your hydrangea arrangement for a few days, dump out the old water and fill your vessel with fresh, cool water. At the same time, give the stems a fresh cut. This will prolong the life of your blooms, and your enjoyment.

Keep Hydrangeas Out of Direct Sunlight

Place your vase of hydrangeas in a spot that does not receive direct sunlight. The sunlight dries out the blooms, and they tend to wilt faster

How To Revive Wilted Hydrangeas

Sometimes, even when you do everything right, hydrangea blooms will wilt. A revival process that may save them begins with filling your kitchen sink with cool water. Plunge the blooms into the water, and let them sit for 30 minutes. I promise they will be OK! When finished, shake off the excess water, and start arranging. Hydrangeas absorb water not only through the stem, but through the petals as well.

Tips For Arranging Hydrangea Bouquets

• Hydrangeas are often full enough to stand alone in a pitcher or vase. If your blooms are smaller than usual, add a few stems of eucalyptus or other greenery to create a fuller arrangement.
• If freshly cut hydrangeas begin to wilt, place the stripped stems in very hot (but not boiling) water and let the water cool completely before arranging them in fresh water. This simple trick can often revive drooping blooms.
• For the longest vase life, keep your arrangement away from direct sunlight, heating vents, and drafts. A cool spot will help the flowers stay fresh and beautiful longer.

Frequently Asked Questions

If you have hydrangeas blooming in your garden, I hope you cut a few stems and bring them indoors to enjoy. And if you don’t have bushes of your own, a simple grocery store bouquet can brighten your home just as beautifully.

If you’d like to grow your own blooms, be sure to see my guide to limelight hydrangeas, where I share practical tips for planting, pruning, and caring for these dependable shrubs year after year. Later in the season, when the blooms become papery and begin to turn pink, they can also be used to make a dried hydrangea wreath for your front door or indoor decor.
