What is plugging?

• A. Nutrient blockage
• B. Air blockage
• C. Stem blockage
• D. Water blockage

Answer: (C)

Plugging is a blockage inside the stem that prevents water from moving up to the flower. Cut flowers rely on water traveling through the stem’s vascular system (the xylem) to stay turgid and open. When a plug forms inside the stem, water can’t rise to the bloom even if there’s water in the vase, so the flower wilts and loses life quickly. That internal stem blockage is what the term “plugging” specifically describes, rather than something forming in the water or at the surface. The other options describe blockages in different places or of different types, but they don’t capture what is happening inside the stem itself. To help prevent plugging, keep stems clean and sharp when cutting, recut under water, remove any leaves below the water line, and use fresh preservative solution to support continuous water uptake.
