Keeping a flower bouquet fresh and vibrant requires a bit of science and care. Here are some science-backed methods to extend the life of your cut flowers:

1. Select Robust Varieties:

   • Choose flowers that naturally have longer lifespans. Varieties like carnations, chrysanthemums, alstroemeria, orchids, and lilies tend to last well due to their hardier structures and slower aging processes.

   • These flowers can stay fresh for up to three weeks.

2. Remove Lower Leaves:

   • When you bring home a bouquet, remove any leaves that would sit below the water line in your vase.

   • Leaves submerged in water can rot quickly, leading to bacterial growth that blocks the stems and causes premature wilting.

3. Cut Stems Properly:

   • Use sharp, sterilized scissors or a knife to make a clean cut at a 45-degree angle about one inch from the bottom of each stem.

   • This angled cut increases the surface area for water absorption and prevents the ends from resting flat at the bottom of the vase.

4. Prevent Air Bubbles:

   • Air bubbles can block water flow through the stem. After cutting, place the stems immediately in water.

   • For plants like poinsettias and poppies that emit milky sap, briefly heat the cut ends with a flame or dip them in boiling water to seal the sap and ensure clear water intake.

5. DIY Plant Food:

   • Create a simple homemade solution: Mix 1 teaspoon of sugar, a few drops of bleach, and 2 drops of lemon juice or vinegar into each liter of vase water.

   • This provides necessary carbohydrates, acidifies the water, and prevents microbial growth.

6. Regular Water Changes:

   • Change the water in the vase every two days to prevent bacterial buildup.

   • Fresh water helps keep your flowers hydrated and looking their best.
