How To Take Care Of A Hydrangea: 9 Steps To Keep It Fresh

May 23, 2025

There’s something undeniably charming about hydrangeas. Their full, cloud-like blooms brighten up any room, whether bunched up in a bouquet or resting elegantly in a vase. But as anyone who’s brought them home knows, these stunning flowers need a little extra TLC to stay their best.

If you’ve ever wondered how to take care of a hydrangea without feeling like handling something too delicate, you’re in the right place. In this guide, we’ll share nine down-to-earth steps to help your hydrangeas stay vibrant, perky, and beautiful—whether they’ve just arrived as a gift or are freshly cut from your garden.

Let’s get into it.

1. Choose The Right Spot To Display

Hydrangeas can be a bit fussy with temperature. If you’re placing a hydrangea bouquet in a vase, choose a cool, shaded space away from direct sunlight or heat sources like stoves, radiators, or even strong overhead lights.

Direct sun dries out the petals quickly, especially indoors. A little light is fine—but think “gentle morning sun” rather than the afternoon blaze.

2. Start With Clean Tools And A Clean Vase

Before arranging your flowers, wash your vase thoroughly with warm water and soap. Bacteria can shorten your blooms’ lifespan, and hydrangeas are extra sensitive to this.

Next, use clean, sharp scissors or floral shears to snip the ends of the stems. Avoid dull blades, as they crush the stems and make water absorption harder.

3. Cut The Stems At An Angle

Snip about 2 to 3 cm off each stem at a 45-degree angle. This increases the surface area for water intake, which is key to keeping hydrangeas from wilting.

You might also gently split the bottom of each stem with a vertical cut. This old-school florist trick encourages better hydration and is especially useful for hydrangea bouquet care.

4. Remove Lower Leaves

Any leaves that would sit below the waterline should be removed. Leaves submerged in water break down quickly and encourage bacteria, which can clog stems and lead to drooping.

For better hydrangea care in vase settings, keep the water fresh and the stems clear. Less gunk in the vase = longer-lasting blooms.

5. Fill The Vase With Lukewarm Water

Hydrangeas don’t respond well to cold water straight out of the tap. Instead, fill your vase with lukewarm water, which helps relax the stems and lets them drink more easily.

If you have a packet of flower food, add it. If not, a teaspoon of sugar and a splash of white vinegar can work in a pinch.

6. Mist The Blooms

Here’s where hydrangeas stand out—they drink through their petals, too! Lightly mist the blooms daily with water to keep them hydrated from the top down.

This step can make all the difference in keeping your flowers fresh and happy, especially if you live in a dry climate or run the air conditioning at home.

7. Give Them A Daily Check

Hydrangeas are known for their thirst. Check the vase's water level daily and top it up with clean water. Change the water completely every 2–3 days and give the stems a quick fresh cut.

If you notice drooping, don’t panic. Submerge the entire head and stem in a sink or bucket of water for 30–45 minutes. Often, they’ll perk back up beautifully.

8. Keep Them Away From Fruit

This might sound odd, but fruits like apples and bananas release ethylene gas, which can age your hydrangeas faster.

If you’re arranging your bouquet near the kitchen or dining table, make sure your fruit bowl is a safe distance away. This is an often-overlooked care for hydrangea tip that makes a subtle but noticeable difference.

9. Revive Wilted Blooms With A Soak

If your hydrangeas look tired after a few days, don’t toss them out just yet. Fill your sink or a big bowl with water and lay the hydrangeas flat, allowing the whole flower head and stem to soak.

Leave them for a few hours, or even overnight. This hydrating bath helps restore limp petals and gives your flower arrangement new life.

How To Pair Hydrangeas With Other Flowers In Arrangements

Hydrangeas are the ultimate team players in floral design. Their full, cloud-like blooms provide a lush base that pairs beautifully with a variety of flowers. Here’s how to create stunning arrangements:

1. Balance With Bold Blooms

Hydrangeas' voluminous nature complements other statement flowers. Consider pairing them with:

Roses: Classic and versatile, roses add elegance and contrast.
Peonies: Their soft, ruffled petals blend seamlessly with hydrangeas for a romantic feel.
Dahlias: These intricate blooms add depth and texture to the arrangement.

2. Add Height And Structure

Introduce vertical elements to your bouquet for visual interest:

Delphiniums: Tall and graceful, they bring height and a touch of drama.
Snapdragons: Their spiky form adds a dynamic contrast to the roundness of hydrangeas.

3. Incorporate Delicate Accents

Soften the arrangement with smaller, delicate flowers:

Baby’s Breath: Adds an airy, whimsical touch.
Lisianthus: Offers a romantic, ruffled look that complements hydrangeas.

4. Enhance With Greenery

Greenery provides a natural backdrop and highlights the vibrant colours of the blooms:

Eucalyptus: Its silvery leaves add texture and a subtle fragrance.
Ferns: Introduce a feathery contrast to the dense hydrangea petals.

5. Consider Colour Harmony

Match or contrast colours for the desired effect:

Monochromatic Schemes: Pair blue hydrangeas with pale blue delphiniums for a soothing palette.
Bold Contrasts: Combine pink hydrangeas with yellow sunflowers for a vibrant display.

Frequently Asked Questions About Taking Care Of Hydrangeas

What Causes Hydrangeas To Wilt So Quickly?

Hydrangeas wilt easily when they don’t get enough water. They absorb moisture through both their stems and petals, so dry conditions or poor hydration can make them droop fast.

How Often Should I Change The Water For Hydrangeas In A Vase?

You should change the water every 2 to 3 days. Daily top-ups also help to keep bacteria at bay and the flowers well-hydrated.

Should I Use Cold Or Warm Water For Hydrangeas?

Use lukewarm water. It’s easier for the stems to absorb compared to cold water, which can cause shock and limit hydration.

Can Hydrangeas Recover From Drooping?

Yes, they can. Try submerging the entire flower and stem in water for 30–45 minutes. This often revives wilted blooms.

Is It Better To Keep Hydrangeas Indoors Or Outdoors?

Cut hydrangeas do best indoors in a cool, shaded area. If they’re planted outdoors with partial shade, and good watering works well.

What’s The Best Way To Extend Hydrangea Bouquet Care?

Mist the petals daily, keep the water clean, snip the stems at an angle, and avoid placing them near direct heat or fruit.
