Extend the Life of Cut Flowers: Commercial and DIY Preservatives Plus Proper Stem Care

Why Flowers Wilt

Cut stems lose their life support. Bacteria clog vascular tissue within hours, blocking water uptake. Necks bend, buds fail, leaves droop.

Commercial Preservatives

Contain three key ingredients:

• Biocide: Kills bacteria, yeast, fungi (most critical).
• Sugar: Food for the flower.
• Acidifier: Lowers pH for better water flow.

DIY Recipes

• 1 tsp citric acid per gallon water.
• 1 tbsp sugar + 1 tsp bleach per gallon water.

Proper Stem Preparation

1. Use sharp knife or shears (not scissors).
2. Cut at 45° angle under water if possible.
3. Remove foliage below water line.
4. Place immediately in preservative solution.

Result

Combined with cool temperatures and avoidance of direct sun/ethylene (fruit), preservatives can double vase life.
