7-day tier
The working band. Reaching seven days requires a sugar source in the water and a biocide or a daily change. This is the band where the vase-solution recipes start to matter more than the cut.

Vase-life ladder
Vase-life band
5 d
The entry band. A stem that clears five days has been cut cleanly, hydrated within a minute and given clean water at least twice. Most soft-stemmed garden flowers live here.
Vase-life band
7 d
The working band. Reaching seven days requires a sugar source in the water and a biocide or a daily change. This is the band where the vase-solution recipes start to matter more than the cut.
Vase-life band
10 d
The keeping band. Stems here are either low-ethylene by nature or have a biocide-tolerant stem structure. Reaching ten days almost always means the water was changed on schedule rather than when it looked dirty.
Vase-life band
14 d
The long-keeping band. Fourteen days and beyond is a property of the stem, not of the care: low transpiration, dense vessels and low ethylene sensitivity. No recipe moves a stem into this band on its own.
