Problems & Solutions


Ethylene Sensitivity


Ranunculus are sensitive to ethylene. To help protect Ranunculus against damage from ethylene exposure, use EthylBloc™ products* during shipping and storage. Do not store or display near ripening produce or products that produce ethylene.


Botrytis Sensitivity


Botrytis can easily develop on flowers. Minimize the development of Botrytis by respecting the cold chain and avoiding temperature fluctuations that could create condensation in sleeves and bunches. You should also avoid getting water on blooms or handling stems by the blooms during processing.


Prone to Mechanical/Physical Damage


Ranunculus stems and blooms are very delicate. Bunches should be secure but not strapped too tightly or stems will bruise or break. Do not over pack boxes to allow good airflow.

  • Ranunculus have an average vase life of 3-7 days.
  • Opening speed can vary based on ambient temperatures.
  • Foliage can have issues with yellowing. Ranunculus may benefit from bulb specific flower foods.
  • Ranunculus can be mixed with most other flowers without any negative or harmful effects, however, do not mix daffodils in the same vase.
  • Due to their shorter vase life, pair with flowers that have similar characteristics. If designing in foam use OASIS® Maxlife foam to reduce potential discoloration of stems. Use a lower density foam like OASIS® Springtime for easier insertion of Ranunculus' hollow stems. Always cut at a sharp angle before inserting into foam. Ranunculus stems tend to be naturally bendy. They rarely grow straight, which adds to their natural aesthetic. But they can be quite delicate as they are hollow. You may find it easier to hold these flowers upside down when handling to prevent breakage. Create designs as close to event as possible. Check water levels or foam periodically to be sure flowers stay hydrated.
  • Use FloraLife® Finishing Touch spray once designs are complete to keep blooms fresh and hydrated.


  • Ranunculus are a sensitive crop that should have a minimal storage period. FIFO (First In First Out) inventory rotation is always our recommendation for the best end consumer experience. We advise a maximum 3-day storage period under strict cold chain conditions.
