To care for marigold flowers in floral arrangements, it's important to follow a few steps to prolong their freshness and keep them looking vibrant. Here are some specific tips:

• Trim the Stems: Before placing the marigolds in water, trim the stems at a diagonal about 1-2 inches (2-3 cm) with a sharp knife or pruning shears. The diagonal cut allows for better water absorption.
• Remove Lower Leaves: Remove any leaves that will sit below the waterline in the vase. Leaves in water can lead to bacterial growth, shortening the lifespan of your roses.
• Use a Clean Vase: Ensure the vase is thoroughly clean before placing the roses. Residual bacteria can quickly multiply and harm the flowers. Wash with soap and water before use.
• Change the water regularly:
• o keep the flowers fresh, change the water every two days or daily if it becomes cloudy. You can also add flower food to extend the roses' life.
• Use lukewarm water: Marigolds respond well to lukewarm water (around 68-77°F or 20-25°C), which helps improve water uptake.
• Avoid direct sunlight: Place the arrangement in a cool spot, away from direct sunlight, heaters, or drafts. Flowers last longer in cooler temperatures.
• Keep away from fruit: Do not place the flowers near ripening fruits, especially apples and bananas, as they release ethylene gas, which speeds up the aging process of flowers.
• Re-cut stems: If flowers start to droop, re-trim the stems diagonally to renew their ability to absorb water.

With these simple care tips, your marigolds will maintain their vibrant colors and stay fresh for longer.
