How to make it last?

1. **Change the Water Regularly:** Stagnant water can lead to the growth of bacteria, which can shorten the lifespan of your flowers. Change the water in the vase every 2-3 days, or whenever it becomes cloudy. Trim the stems slightly each time you change the water. 

2. **Trim the Stems:** Using sharp scissors or pruning shears, trim about half an inch off the bottom of each flower stem at a 45-degree angle before placing them back in the vase. This helps the flowers absorb water more effectively. 

3. **Remove Wilting Flowers:** As soon as you notice any flowers or leaves starting to wilt or yellow, remove them from the arrangement. This prevents ethylene gas produced by decaying flowers from affecting the remaining blooms. 

4. **Keep the Vase Clean:** Rinse the vase with warm, soapy water and rinse thoroughly when you change the water. This removes any bacteria that may have built up and helps keep the water clean. 

5. **Use Flower Food:** If your floral arrangement came with a packet of flower food, use it according to the instructions. Flower food contains nutrients and antimicrobial agents that can extend the life of your flowers. 

6. **Avoid Direct Sunlight and Heat:** Keep your floral arrangement away from direct sunlight, heating vents, and appliances that emit heat. Excessive heat can cause the flowers to wilt prematurely. 

7. **Maintain Proper Humidity:** Flowers last longer in a moderately humid environment. You can lightly mist the petals and foliage with water to help maintain humidity if you live in a dry climate. 

8. **Keep Away from Fruit:** Ethylene gas released by ripening fruits can accelerate the aging process of flowers. Store your floral arrangement away from fruit bowls or ripening fruit. 

9. **Re-Arrange as Needed:** As your flowers age, they may change position and need to be rearranged. Gently adjust the placement of the flowers to maintain the desired look. 

10. **Consider Flower Type:** Different flowers have different care requirements. Some may benefit from being recut and rearranged more frequently than others. Research the specific care needs of the flowers in your arrangement. 

11. **Monitor Water Level:** Ensure that the vase is always filled with enough water to cover the stems. Some flowers can drink a lot of water, so check the water level daily, especially in the first few days after arranging.
