How to Keep Hydrangeas Fresh in a Vase Up to 10 Days

Why Hydrangeas Wilt So Fast

Hydrangeas are extremely thirsty flowers. Their large blooms require a constant and heavy supply of water to stay open. The moment that supply is interrupted even slightly the flowers begin to droop. This is why they wilt faster than roses, tulips, or almost any other cut flower.

The good news is that wilting does not always mean dead. If you catch it early enough hydrangeas can be fully revived.

The First Thing to Do When Your Hydrangeas Arrive

Do not put them straight into a vase with regular water. First fill a clean bucket or sink with room temperature water. Cut about 3 centimeters off the bottom of each stem at a sharp 45 degree angle using a clean sharp knife or scissors. Do this while the stem is underwater if possible to prevent air from entering the stem and blocking water flow.

There is one step that makes a significant difference with hydrangeas specifically. After cutting the stem dip the cut end into a small amount of alum powder, which is a common kitchen spice. Alum acts as an astringent that keeps the stem tissue open and maximizes water absorption. If you do not have alum you can also lightly crush or split the bottom 2 centimeters of the stem to increase the surface area for water intake.

Place them in the water immediately after cutting and let them condition for at least one hour before moving them to a display vase.

Choosing the Right Water and Vase

Use a very clean vase. Bacteria is the primary enemy of hydrangeas and they are more sensitive to it than most flowers. Wash your vase thoroughly with soap and hot water before use. Fill it with cool clean water and add the flower food packet that comes with your delivery. Flower food contains the nutrients and antibacterial agents that hydrangeas need to stay open.

Fill the vase generously. Unlike roses which prefer less water hydrangeas drink heavily and benefit from a fuller vase. Change the water completely every two days and recut the stems each time.

One Trick Most People Never Use

Hydrangeas can absorb water through their petals as well as their stems. If your hydrangeas begin to droop submerge the entire bloom head in a bowl of cool water for 30 to 45 minutes. This method called floating rehydrates the petals directly and can bring a wilted hydrangea back to full life. It works remarkably well if done within the first 24 hours of wilting.

Where to Keep Them in Your Home

Place hydrangeas away from direct sunlight, heating vents, and ripening fruit. Direct sun dries them out quickly. Heat from vents causes rapid moisture loss. Ethylene gas from nearby fruit accelerates aging in all cut flowers but hydrangeas are particularly sensitive to it.

A cool shaded area with good air circulation is ideal. At night moving them to a cooler room extends their life noticeably.

How Long Hydrangeas Last With Proper Care

Without any special care hydrangeas last 2 to 4 days. With the steps above they consistently last 7 to 10 days. The difference is entirely in the handling from the first 30 minutes onward.
