Roses are some of the most beautiful flowers that you can add to your garden. And as cut flowers, they can also be a gorgeous addition to your home. However, fresh roses don’t last forever. In this article, I’ll share some tips detailing how to make fresh roses last longer in a vase.
How to Make Fresh Roses Last Longer in a Vase – The Essentials
Fresh roses usually last approximately one week in a vase. However, you can eke that out to ten days by changing the water regularly. Use floral preservatives or alum powder to provide extra nutrients and help your roses absorb more water. Keep your roses somewhere cool and away from direct sunlight.
Roses are deciduous woody perennials from the Rosaceae family. The Rosa genus contains hundreds of species mainly native to Asia as well as thousands of cultivars. Some roses are also native to parts of Europe, North Africa, and North America.
Roses have colorful single, double, or semi-double flowers with five petals. These plants are shrubs or climbing vines with woody stems covered in prickly thorns and elliptical leaves with serrated margins (though there are some thornless climbing roses). Many types of rose flowers also have gorgeous heady or musky scents.
Most roses are divided into three main groups; old garden roses, modern or hybrid roses, and species roses. Roses can also be subdivided into smaller groups, including Floribunda roses, miniature roses, and patio roses.
How Long Do Cut Roses Last in a Vase?
Cut roses usually last approximately 7 to 10 days in a vase. While this doesn’t sound like much, you can push it a bit further using a few tips. However, once your roses start to droop and wilt, they won’t last much longer. You can keep your roses going for a few more days using the tips below.
How to Harvest Roses for Cut Flowers
One of the best ways to help your roses last longer in a vase is to harvest them correctly. This ensures that your roses are as healthy as possible before you put them in the vase. The healthier your roses are, the longer they will last. Here’s a concise guide explaining how to harvest roses for cut flowers:
- Take your chosen vase and thoroughly wash it out using warm, soapy water. Then leave it to dry.
- Cut your roses early in the morning. Roses contain more water at this time of day, meaning they can handle being placed in a vase.
- Choose roses that are just starting to open. The exterior petals should have unfurled, but the main petals should still be closed. Don’t choose any roses that have brown spots or limp petals.
- Cut your roses just above any unopened buds or a pair of healthy leaves.
- Trim the stems down slightly so that they fit into the vase. Cut the bottom of the stem at a 45-degree angle as this will help the flower absorb more water.
- Remove the leaves and any brown or green guard petals. However, leave the thorns on the stem.
- Fill approximately three-quarters of the vase with lukewarm, room-temperature water.
- Apply a dose of floral preservative. Alternatively, you can let a teaspoon of sugar dissolve in the water.
- Position your roses in the vase and arrange them as desired.
- Place the vase somewhere cool and away from direct sunlight. Don’t leave your vase near any radiators, air vents, or open windows that produce drafts.
- Change the water every few days. Each time you replace the water, trim off another inch of the stem at a 45-degree angle. Apply another dose of floral preservative or sugar.
How to Make Fresh Roses Last Longer in a Vase
Whether you buy them from a florist or harvest them yourself, fresh roses should last for about a week in a vase. However, using a few tricks, you can eke out a few more days of these beautiful flowers. Here are a few ways to make your fresh roses last longer in a vase:
Position the Vase Correctly
The easiest way to help your roses last as long as possible is to put them in the right place. Always position your jar of roses in a cool location away from direct sunlight. If you leave the vase in the sun, the water will evaporate more quickly, shortening the life of your roses.
It’s also essential to keep your vase of roses away from cold or dry drafts. Air vents, heaters, and open windows usually cause these drafts. Again, the dry air causes more water to evaporate, making your roses wilt more quickly.
Change the Water Regularly
The most important thing with any cut flower is to change the water regularly. This keeps your roses hydrated, which helps them last longer. Always use lukewarm or room temperature water because cold or hot water can shock your roses. This stress causes your roses to wilt quickly.
Whenever you change the water in the vase, it’s important to also trim the stem. Always cut the stem at a 45-degree angle, as this helps your rose to absorb more water. Trimming the stem like this each time you change the water helps keep your rose fresh and healthy.
Use a Floral Preservative or Sugar Solution
The roses in your vase need two things to stay alive; water and nutrients. To provide plenty of nutrition, add a dose of floral preservative each time you change the water. If you bought your roses from a florist, they should come with a packet of flower food or floral preservative.
If you don’t have any floral preservatives, you can use sugar instead. Let one teaspoon of sugar dissolve in the water before adding your roses back in. That said, floral preservatives or flower food always work better than sugar.
Use Alum Powder
Another way to make your roses last longer is to use some potassium aluminum sulfate, also known as alum powder. Alum powder is made from potassium aluminum sulfate crystals and is usually used when pickling vegetables. You should be able to find alum powder near the pickling spices in your local grocery store.
Alum powder helps your roses absorb more water, which helps keep them fresh and healthy. If you decide to use alum powder, add a small amount each time you change the water in the vase.
