Give each stem a fresh cut at a 45-degree angle (1–2 cm from the end). This helps them soak up water more efficiently and prevents them from sitting flat in the vase, which can block water flow. For woody stems like roses or lilacs, a quick soak before arranging can improve water uptake. 

Pour enough water to cover all the stems and keep them hydrated. Start with lukewarm water (around 80–110°F) and change it every 1–2 days. Flower food helps too! Out of flower food? Make a DIY version with a splash of vinegar, a spoonful of sugar, and warm water. 

Flowers do best in a cool spot away from direct sunlight, drafts, or vents that can dry them out. If you really want to extend their life, consider placing them in the fridge at night. Just think of it as beauty sleep for your blooms! 

Leaves sitting below the waterline can rot and invite bacteria, so trim them off before arranging. Also, remove any wilting flowers to prevent bacteria from spreading to healthy blooms. 

Fruits like apples and bananas emit ethylene gas, which can speed up the aging process for flowers. Keep your arrangement away from these fruits to help them stay fresh and lovely longer.
