How to Store Flowers Overnight
If you must hold flowers overnight, recut and hydrate them, then leave them in a cool interior room. A refrigerator can help if it is not too cold and contains no fruit.
- Recut and put stems in water as soon as you can.
- Use a cool room. Avoid garages that freeze or overheat.
- If using a fridge, keep flowers away from fruit and from vents that ice the petals.
Tulips and orchids have different cold tolerances; when in doubt, a cool room is safer than a very cold fridge.
