The secrets of the longevity of roses in a vase

Roses are a symbol of beauty and love that happily adorn any space with their splendor. But how to make these ephemeral creatures delight the eye as long as possible after they have been cut and placed in a vase? 

Preparing the vase: Creating the perfect 'home' for flowers

- Wash the vase: Wash the vase thoroughly with warm, soapy water to remove any remaining bacteria and fungi.

- Rinse: After washing, rinse the vase well so that no soapy residue remains.

- Disinfecting: You can additionally wipe the vase with a disinfectant, such as a solution of bleach diluted with water, and then rinse again thoroughly.

- Adjusting the size: Make sure that the height of the vase matches the length of the rose stems. It is ideal to leave the top third of the stems above the edge of the vase.

- Filling with water: Fill the vase with room temperature water. Using cold water can slow down the water absorption of the roses, while warm water speeds up bud opening.

- Adding nutrients: A special preservative for cut flowers can be added to the water, which provides the roses with essential nutrients and keeps the PH of the water balanced.

Stem treatment: Ensure maximum water absorption

- Cutting at an angle: Use a sharp knife or secateurs to make a cut at about a 45-degree angle. This increases the surface area for water absorption and prevents the stem from "sticking" to the bottom of the vase, which would block water absorption.

- Update the cut: Update the cut every 2-3 days to keep the stems from clogging and to better absorb water.

- Removing excess leaves: Remove any leaves that will be below the water level in the vase. Leftover leaves can be a source of bacteria.

- Avoid damage: Avoid crushing or damaging the stems as this can interfere with water absorption.

- Prevent air blockage: Place stems in water immediately after cutting. This prevents air from entering the vessels of the stems, which could block the flow of water.

Water for roses: Water temperature and quality

- Water Temperature: Room temperature or slightly warm water is best. Cold water slows water absorption and can shock plants, while warm water promotes rapid bud opening and accelerated bacterial growth.

- Water quality: Use soft, settled water, preferably chlorine-free and low in minerals. If possible, use distilled or filtered water.

- Water changes: Change the water in the vase regularly every 2 days to prevent bacterial growth and keep the water clean.

- Additives: Use cut flower preservatives, which often include nutrients to stimulate rose health and bacteria-fighting agents.

Vase location: The effect of light and temperature on roses

- Light: Roses need adequate light, but direct sunlight can cause overheating and rapid wilting. Choose a spot with diffused light or in semi-shade.

- Temperature: Avoid placing roses near sources of heat or cold such as radiators, air conditioners or drafts. The ideal temperature for roses should be cool but not cold.

- Humidity: Too little humidity can lead to rapid wilting. If the indoor air is dry, consider using a humidifier.

- Distance from fruit: Do not place roses near fruit as it releases ethylene, a gas that can accelerate flower wilting.

Successful rose vase placement takes all of these factors into account to create the conditions most conducive to keeping them fresh and beautiful.

When roses wilt: How to revitalize wilting flowers

- Stem pruning: Make a new cut on the stems and remove wilted leaves and petals.

- Cold water: Use cold water to "shock" roses and encourage them to absorb water.

- Removing air from the stems: Dip the stems for a few seconds in hot water and then move them back to cold water. This can help remove air bubbles that block the water's path up the stem.

- Moisturizing petals: You can gently spray rose petals with water to increase moisture.

Roses are more pleasing to the eye for longer if they are properly cared for

The secret to the longevity of roses in a vase lies in constant attention and regular care. Water renewal, proper water temperature and quality, regular cut renewal and optimal vase placement help to keep these graceful flowers fresh and beautiful. With proper care, roses can delight you much longer than usual.
