🌹 Why Do Flowers Wither Quickly in a Vase? Causes and Solutions 🌿

Nothing brightens up a room like a beautiful bouquet of fresh flowers. 🌸 However, it’s frustrating when these flowers fade quickly after placing them in a vase. Why do cut flowers lose their freshness so quickly? What are the factors that cause them to fade, and how can you extend their lifespan? In this article, we’ll explore the main reasons why flowers fade quickly and give you tips on how to keep them looking beautiful for longer. 🌿


🌿 1. Why Do Flowers Wither Quickly in a Vase? The Main Causes 🌷

1.1. Formation of Bacteria in Water

  • Explanation : One of the most common reasons why flowers wilt is the growth of bacteria in the vase water. These bacteria clog the stems of the flowers, preventing water from rising to the petals.
  • Solution : Change the water every 2 days and clean the vase well to prevent the proliferation of bacteria.

Tip : Add a few drops of white vinegar or a piece of activated charcoal to the water to slow the growth of bacteria.

1.2. Absence of Bevel Cutting of Stems

  • Explanation : When flower stems are not cut properly, they have difficulty absorbing water. A straight cut can block the entry of water and cause them to dry out more quickly.
  • Solution : Cut the stems at an angle (at a 45° angle) with a sharp knife before placing them in the vase. This increases the surface area for water absorption and helps the flowers stay hydrated longer.

  • Solution : Use filtered water or slightly softened lukewarm water to fill your vase.

1.4. Exposure to Heat and Direct Sunlight

  • Explanation : Flowers are sensitive to heat and direct sunlight. Excessive exposure to heat accelerates water evaporation and the wilting process.
  • Solution : Place your vase in a cool place, away from heat sources (radiators, electronic devices) and direct sunlight.

1.5. Proximity of Fruits

  • Explanation : Fruits give off a gas called ethylene which speeds up the aging process of flowers, causing them to fade more quickly.
  • Solution : Keep your bouquet away from any fruit baskets or other items that could give off this gas.

1.6. Air Bubbles in Stems

  • Explanation : When a flower is cut, air bubbles can enter the stems, blocking the absorption of water. This prevents water from circulating properly, causing the flowers to dry out more quickly.
  • Solution : Cut the stems under running water before placing them in the vase to remove air bubbles.

🌿 2. How to Extend the Life of Your Flowers in a Vase?

🌸 2.1. Use Flower Food

  • Flower food, often included with bouquets, contains essential nutrients that extend the life of flowers. If you don't have any, add a teaspoon of sugar and a few drops of white vinegar to the water.

🌸 2.2. Change the Water Regularly

  • Change the water in the vase every 2 days and clean it well each time. This prevents the growth of bacteria and ensures a clean environment for your flowers.

🌸 2.3. Avoid Overfilling the Vase

  • Flowers don't need a vase filled to the brim with water. Fill it halfway up the stems to allow for better water circulation.

🌸 2.4. Place the Flowers in a Cool Place at Night

  • If possible, place your bouquet in a cool place or in the refrigerator overnight to slow the wilting process.
