How to Make Roses Last Longer in a Vase: 7 Simple Tips

Roses look beautiful whether they’re standing alone or part of a mixed bouquet. However, cut roses can quickly start wilting if you don't know how to keep them fresh in a vase of water. Use these easy tips to extend the life of your roses, and find out which home remedies you can skip.

To make cut roses last as long as possible, two crucial steps are avoiding bacterial growth and ensuring the stems can soak up as much water as possible. Start with a clean vase, free of any grime from your previous floral arrangement. Wash the vase with soap and water to eliminate any lingering bacteria.

Trim the stems of your roses at a 45-degree angle. This angled cut exposes more of the stem to water, helping the flowers soak up as much as possible. Use clean pruning shears, kitchen scissors, or flower snips to make your cuts.

While trimming, remove any leaves along the stem that will be below the water line in the vase. Submerged or wet leaves are a breeding ground for bacteria, which can shorten the lifespan of your roses.

However, it's better to leave the thorns intact. They won't deteriorate in the water like leaves, and cutting off the thorns can damage the stems making it easier for bacteria to grow.

When filling the vase, use water that’s room temperature—water that’s too hot or too cold can shock the roses. Most bouquets come with a packet of flower food, which you should add to the water. Flower food typically contains sugar (to help blooms open), citric acid (to prevent bacterial growth), and a biocide like bleach (to disinfect the water).

Follow the instructions on the flower food packet regarding the amount to use. Add the recommended amount to the water and stir until it dissolves. Then, place the roses in the vase.

If you don’t have flower food, try adding a little mouthwash to the water to help reduce bacterial growth.

A surprising trick to help your roses last longer is to refrigerate the cut flowers. Place the entire vase in your fridge before going to bed, and take it out in the morning. As long as the temperature doesn’t drop below 32°F, the cool air helps slow down the natural aging process of the petals.

Empty the vase and change the water every two or three days, sooner if it looks cloudy or murky. Also, stir in more flower food each time you refill the water. It's a good idea to re-trim the stems when you change the water—a fresh cut will make it easier for the stems to absorb water.

Although roses love sun when growing in a garden, keep your cut bouquet out of direct sunlight. Sun can damage and dry out your roses, causing them to wilt faster. Avoid placing the arrangement in areas with extreme temperatures, including near windows in winter (cold drafts can harm the blooms) and near vents that blow hot or cold air directly on the flowers.

Apples and bananas produce ethylene gas, which speeds up the ripening process in fruits and flowers. Keep your vase away from your fruit bowl. This also applies to wilted roses in your bouquet, as they produce more ethylene gas, causing nearby flowers to wilt faster. Remove any wilted blooms quickly to help the remaining flowers stay fresh longer.

You might have heard that adding aspirin, vodka, or a penny to water can help your roses last longer. While these methods aren't likely to harm your bouquet, there's little evidence they make a significant difference in extending the life of your roses.

The idea behind these tricks is that they prevent bacterial growth, but a mix of water and flower food can do that without needing extra additions. However, if you find a trick that works for your roses, feel free to use it. But the best way to keep your roses fresh is by properly prepping the flowers and vase and regularly refreshing the water to discourage bacteria.
