Flower care for Hydrangeas

Hydrangeas are amongst the most impressive and beautiful flowers that we work with in our Raffles Place flower shop. However, many hydrangeas bouquets often wilt after 2 to 3 days.

We will be explaining the main reasons why hydrangeas wilt fast and ways to prevent it from happening

Why hydrangeas are used in flower arrangements

Apart from being great main flowers for flower bouquets, hydrangeas are also great building blocks for luxurious floral arrangements in jars and boxes. Hydrangea flower jars elevate the space in which it is placed, giving it a classy look and feel.

Hydrangeas are often associated with gratitude and appreicaiation. This meaning has made hydrangeas popular amongst clients who are either buying for a colleague who has left the team or for help rendered during a long leave of absence. It As appreciation is pretty generic, they are also popular flowers for a birthday girl.

Hydrangeas Having a dark blue hydrangea in the bouquet will look radically different from say a light pink alternative. One is slightly more masculine while the other has a more rustic pastel feel to it. As the hydrangea has a big flower head, it is naturally the focal point of any bouquet. Hence it is important to get the color of the hydrangea right.

Why Hydrangea Bouquets wilt fast

The two main reasons why cut hydrangeas wilt are as follow:

  1. Lack of water
  2. Heat

Lack of water

Every flower bouquet that we sell will have a small pack of water or flower food hidden within the packaging. This small plastic bag that is stashed away underneath all the flower wrapping provides the flower with the much needed water so that they can continue to be fresh.

However, this small pack of water can only last so long. If clients were to leave the bouquet on the table for three days in the original packaging, they will not know that the flowers have probably used up all the water in the hidden bag. With no source of water, flowers wilt really fast.

This is especially true for hydrangeas due to the higher than normal water intake of these flowers.


We know that the Singapore temperature can be hot and humid. As some clients carry their hydrangea bouquets around in the afternoon sun, the excessive heat an cause the cellular structure of the flower to collapse and expedite the wilting of the hydrangea.

It does not help that the heat also causes rapid evaporation of moisture and further saps any water that the hydrangea bouquet has to thrive.

Keeping Cut Hydrangeas Fresh

Today, we will be sharing some key points which will help you keep your hydrangeas pristine for much longer.

Colors of Hydrangeas

One of our favorite hydrangeas is white hydrangea. However, this is one of the most difficult arrangements to pull off. This is because a white hydrangea must be very fresh as any signs of browning or aging on the petals is very obvious and will ruin the feel of the entire floral design. That said, the beauty and the purity of the bouquet makes it all worth it when we do put one together.

Unusually thick stem

When choosing hydrangeas for your bouquet, there are some things to take note of especially when it comes to trimming and priming the hydrangea for the floral arrangement.

One of the things that shocked us when we first tried our hands at hydrangea is how thick the stem is. While it may seem like a trivial matter, the thickness of the stem makes it difficult to cut and trim the roots without damaging other parts of the stem. The larger circumference of the stem also makes it a more difficult flower to maneuver when doing the arrangement.

Trimming a new hydrangea

When hydrangeas come fresh from the wholesaler, it normally comes with individual plastic wrapping around it. They will also look a little dry and lazy as they have been dehydrated before they were exported all over the globe.

One of the first things that you will need is a clean container that is at least two third the height of your hydrangea. This is because the stem of the hydrangea will firm up when it receives water. With a sufficiently tall container, it will prevent the flower from toppling over and result in a crooked stem that will increase the difficulty of the floral arrangement much later.

After removing the wrapper, we would have to tend to the stem of the flower. The reason why we need to trim it is simple, the stem of the hydrangea is often too long for our purpose when it comes to floral arrangement.

When you are about to trim the hydrangea’s stem, you will need to do a few things. Firstly, you will need to trim the extra leaves from the flower. This will prevent the leaves from dropping into the water which encourages bacteria growth. Removing the leaves also prevents them from competing with the hydrangea flower for nutrients and water.

After tending to the additional leaves, the next step will be to cut some of the stem away. This stem is to be done with a sharp knife and at an angle so as to maximise the amount of water intake for the flower. One good trick is to do a crosscut at the bottom of the stem This will increase the amount of water intake for the stem.

Saving a wilting hydrangea

IF the hydrangea looks like it is wilting, a good remedy is to immerse the head of the hydrangea in water. Keep the head submerged for about half an hour and let the plant hydrate itself. Once done, place two or three inches of the stem into hot water to eliminate any residue sap that will prevent water uptake. Once done, your hydrangea should be good as new!
