How to make cut flowers last longer

Once cut, flowers no longer have their roots which would usually act as water filters, keeping the flower hydrated and blocking bacteria from travelling into the stem. A flowers roots also provide a source of clean, PH balanced water to flow through the flower as well as feeding the plant with all the minerals it needs. This means that when the flower is cut from its roots, it is also separated from its cleaning, filtering and feeding system leaving it exposed to draw in unclean water and bacteria. That’s why you have to look after your flowers and act as their filtering system, ensuring the flower doesn’t take in anything it shouldn’t.

Clean your vase before putting flowers in it

As we established before, cut flowers have the ability to draw up bacteria and dirt which is why we need to prevent this before they have the opportunity to do so. Since often your vase has been sitting in a cupboard collecting dust, it is very important to remove any bacteria from your vase by thoroughly cleaning it before putting flowers in it. This is best done with some warm water and a small-cap of bleach. Once washed, leave to dry naturally upside down, rather than using a towel which could spread bacteria back onto the vase.

Ensure your water is the right temperature

This may seem like a strange one but flowers actually find it easier to take in warmer water than they do colder water so ensure your water is room temperature before exposing flowers to it. You should also only fill up the vase about a quarter of the way because stems only absorb water from the bottom so any further is likely to increase the probability of rotting stems. Now that you have about a quarter of a vase of room temperature water, it is important to leave the water to settle until the air bubbles are all dissolved since these can interfere with water uptake for the flowers.

Put flower food into the water

Our flower food has been scientifically crafted to provide flowers with the perfect amount of minerals they need so using this is very important to make your flowers last longer. A sachet of flower food is enough for about one litre of water so it is best to split this into two and only use half the flower food in the first vase of water, saving half for a water replacement in a few days.

Remove any rogue leaves and trim the stems

Any leaves that are below the surface level of the water will introduce bacteria into the vase and could cause infections in your flowers so it is important to remove these before putting the flowers in the vase. You also will need to trim the stems before they go into your vase by measuring them against the vase height and then cutting the stems on a 45-degree angle with a clean pair of sharp scissors. By cutting your flowers on an angle, you will be increasing the surface area of the stems so that they have a bigger area to take water in from, which will increase vase life.

Place them in a suited location

Flowers should be kept in a cool area away from direct sources of heat such as radiators, direct sunlight or cookers, they should also be kept away from any fruit or vegetables as this can cause wilting.

Replace the water every two to three days

Once you have found a suitable location to display your flowers, you should keep an eye on them to ensure the water has not gone cloudy and the stems are not wilting. We would recommend taking your flowers out of the vase every two to three days and trimming them on an angle to allow clogged stems to reopen and take in more water. When you take the flowers out to trim them, it is a good opportunity to change their water using the same methods as before and adding the last of the flower food to the water.
