Why do cut flowers die quickly?
Show answer & explanation
Answer: Stems blocked by air bubbles
Stems blocked by air bubbles ✓ — Correct! When stems are cut, air enters xylem vessels, creating bubbles that block water transport. Bacteria also multiply at cut ends, clogging vessels. Without water, cells lose turgor and flowers wilt. Solutions: cut stems underwater, use clean water, add flower food (sugars + antimicrobials), trim stems regularly!
Flowers expire naturally fast — Wrong. Flowers don't just 'expire fast'—they die from inability to absorb water due to air bubbles and bacteria blocking xylem after cutting.
Bacteria in vase water — Wrong. Bacteria do contribute by clogging stems, but the main issue is air bubbles entering xylem vessels immediately when cut, blocking water transport.
