Most mixed bouquets are happiest in a vase filled about halfway. This gives stems plenty to drink without submerging too much foliage. Roses, hydrangeas, and other thirsty flowers benefit from a generous water level, while soft or hollow stems can weaken when placed too deeply.
Check the level every morning because a fresh bouquet can drink surprisingly quickly on its first days. Top up clear water, but replace it completely if it smells stale or looks cloudy. Always rinse the vase before refilling so residue does not return to the clean water.
Quick tips
Mixed bouquets
Begin with the vase half full and check the level each morning.
Thirsty blooms
Roses and hydrangeas need reliable access to plenty of clean water.
Soft stems
Tulips and other tender stems usually prefer a shallower, frequently refreshed fill.
