How do florists keep hydrangeas from wilting?

Hydrangeas are a beautiful and popular flower for many occasions, but they are notorious for wilting quickly. The wilting can be frustrating for both florists and customers alike, especially if the flowers are for a special event or occasion. Thankfully, there are some tips and tricks that florists use to keep hydrangeas fresh and looking their best for as long as possible.

The Importance of Water

One of the most important factors in keeping hydrangeas from wilting is making sure they have enough water. Florists often recommend changing the water in the vase or container every day or every other day to keep the flowers hydrated. This may seem like a hassle, but it can make a big difference in the longevity of the flowers.

The size of the vase or container is also important – the container should be large enough to hold the stems without crowding them. This allows the flowers to have plenty of room to take in water and stay hydrated.

The Fresh Cut

Another important step in keeping hydrangeas fresh is to give them a fresh cut before arranging them in a vase or container. Florists recommend cutting the stem at a 45-degree angle and trimming off any leaves that will be submerged in water.

But what about the milky sap that hydrangeas are known for producing when they are cut? Some florists recommend dipping the cut end of the stem in boiling water for a few seconds to seal the cut and prevent the sap from leaking. Others recommend dipping the stem in alum powder before placing it in water. Alum is a type of salt that can help the flowers take in water more effectively.

Conditioning the Flowers

Conditioning the hydrangeas before arranging them is another important step in keeping them fresh and preventing wilting. Florists may recommend placing the stems in a bucket of warm water for a few hours before arranging them to help them hydrate. Some florists also recommend adding a floral preservative to the water to help the flowers last longer.

Storing Hydrangeas

If you need to store hydrangeas before using them, there are a few things to keep in mind to help prevent them from wilting. First, make sure the flowers are stored in a cool area that is out of direct sunlight. Direct sunlight can cause the flowers to overheat and wilt more quickly.

It’s also important to keep the flowers hydrated while they are being stored. One way to do this is to wrap the stems in wet paper towels and place them in a plastic bag. This can help keep the flowers moist and prevent them from wilting.


Hydrangeas are a beautiful and popular flower that can make any occasion feel special. But if they wilt quickly, the effect can be disappointing. Fortunately, with a few tips and tricks from florists, it’s possible to keep hydrangeas fresh and looking their best for as long as possible.

By making sure the flowers have enough water, giving them a fresh cut, conditioning them properly, and storing them correctly, you can help ensure that your hydrangeas will stay vibrant and beautiful for days to come. Whether you’re a florist or just someone who loves hydrangeas, these tips can help you get the most out of these lovely flowers.


How do you take care of hydrangeas in floral arrangements?

Hydrangeas are a popular choice for floral arrangements due to their large, showy blooms that come in an array of beautiful colors. However, like all flowers, hydrangeas require proper care and attention to keep them looking fresh and beautiful for as long as possible.

One essential step in taking care of hydrangeas is to re-cut their stems before placing them in water. Use a sharp pair of scissors or pruning shears to cut the stems at a slant, which will allow them to take in more water and nutrients. It’s also essential to remove any foliage that will be below the waterline, as this can lead to bacterial growth that will decrease the lifespan of the flowers.

Changing the water in the vase regularly is another vital step in keeping hydrangeas fresh. Replace the water and clean the vase daily or every other day, or whenever the water appears cloudy or murky. This is because the bacteria that grow in stagnant water can quickly accelerate the wilting process.

Hydrangeas are also heavy drinkers, so it’s crucial to make sure that they always have plenty of water. Check the vase frequently to ensure that there is always enough water to cover the bottom of the stems, as dry stems can cause the flowers to wilt and die.

Finally, providing hydrangeas with flower food will help extend their lifespan. You can purchase flower food from a florist or make your version by mixing one tablespoon of sugar and 1/4 tablespoon of household bleach into a gallon of water. The sugar will provide the flowers with energy, while the bleach will help to inhibit bacterial growth in the water.

Taking care of hydrangeas in a floral arrangement involves cutting their stems, changing the water regularly, providing plenty of water, and providing them with flower food. With proper care, hydrangeas can remain fresh and beautiful for up to two weeks or more, making them a delightful addition to any home or event.

Why did my hydrangea wilted overnight in vase?

Hydrangeas are a beautiful bloom that can brighten up any floral arrangement. However, it is not uncommon for them to wilt and droop just overnight when placed in a vase. This sudden change in their appearance can be quite disheartening, especially if you have prepared a beautiful flower arrangement for a special occasion or gathering.

There are several reasons why hydrangeas may wilt so quickly after being cut. One of the main reasons is that hydrangeas have a sticky substance in their stems that can clog the stem, preventing moisture from reaching the top of the stem and the flower head. This lack of moisture causes the flower to wilt and droop.

To avoid this happening, it is recommended to cut the stem of the hydrangea by around 10 cm and submerge it in boiling water. Leave the stem in the water for at least 24 hours. This process helps to break down and dissolve the sticky substance in the stem, allowing the flower to draw in moisture, and stay fresh longer in a vase.

Another reason why hydrangeas may wilt overnight in a vase is that they are simply not getting enough water. Hydrangeas require a lot of water, and if they do not get this water, they can quickly dry out and wilt. It is important to make sure that the vase you are using is large enough for the blooms and has plenty of water. Keeping the vase filled with fresh water and changing it every few days will also help to keep your hydrangeas looking fresh and beautiful.

There are several reasons why hydrangeas may wilt overnight in a vase. Clogged stems and lack of water are two of the most common reasons. By taking steps to keep the hydrangeas’ water supply flowing, you can help to prevent wilting and keep your blooms looking fresh and vibrant for longer periods. Remember to cut the stems short and put them in boiling water for 24 hours before placing them in a vase to enjoy stunning hydrangeas in your floral arrangement for a long time to come.

What do you spray on hydrangeas to preserve them?

Hydrangeas are beautiful flowers that can be a stunning addition to any home decor or event décor. If you want to preserve your hydrangeas and keep them looking fresh for a longer time, you can try spraying them with a simple solution. One efficient way to extend the lifespan of hydrangeas involves using hairspray.

First, it is important to note that you should only spray the flowers once they are fully dried. If they are still wet, the water droplets will mix with the hairspray and create a sticky mess. So, it is best to let the flowers dry out completely for a day or two before using hairspray on them.

Next, choose an aerosol hairspray over a pump spray. Aerosol hairspray is best because it provides a fine mist that covers the flowers evenly, while pump sprays tend to deliver a heavier application in certain areas. Be sure to check the label of the hairspray to make sure that it is non-toxic and suitable for use on flowers.

After you have selected your hairspray, hold the can about 12 inches away from the dried hydrangeas and spray a light mist over the flowers. Move the can around the bouquet to ensure that you cover all the flowers evenly.

The hairspray will help to form a protective coating on the petals that will help to keep them from wilting and protect them from handling and transportation. The spray should keep the hydrangeas looking fresh for up to a week or two, depending on the conditions, such as temperature and humidity levels.

To preserve hydrangeas, you can spray them with aerosol hairspray once they are fully dried. Doing so will create a protective coating on the flowers that will prolong their lifespan and keep them looking fresh and beautiful for a longer time.
