I bought a bouquet of flowers today (Saturday) but I must give them on Monday
How should I preserve them?
- in water?
- in closed room without sun?
- in a fresh room ?
- at what temperature ?
Florists keep cut flowers
How long flowers keep depends on how fresh they were when you received them and the species. See here for more details.
I'd better jump in here...do not use anything in your water. Two days is no big deal. Cold water, no direct sun and a cool place is perfect. Do not put in your refrigerator. Especially if you have ever had apples stored there! They give off a gas that will definitely age your flowers quickly. What kind of flowers are we discussing? Did you cut your stems when you got home and put them in water? Your florist would be more than happy to hold them for you for two days (if you make nice) in a walk-in frig that has never seen an apple. If they are roses, hopefully you've made your cuts under water before putting them in fresh, unadulterated water. Otherwise, there will be air bubbles that will block water to the flower and causes the heads to droop. That stuff they give you to 'prolong' the life of flowers is a scam. I know because I've been a florist and thought that was a horrid way to get return clients! Grin!
If the flowers are not too tall, or if you are willing to rearrange your fridge, some flower bouquets (especially spring bulbs like tulips or daffodils) keep well in the refrigerator.
2 days is really no big deal as long as you keep your flowers out of bright sunlight or near a radiator.
I'm a florist in Essex UK and we would expect our cut flower bouquets to last 10-14 days. We have customers who contact us complementing that their flowers have lasted 3 weeks!
We do not do anything special, just cut stems with a very sharp knife or secateurs. We use trade food in the water but fresh water will be fine.
I add a drop of dawn dish soap and 12 ounces of lemon lime soda to the water and it keeps flowers pressure longer than anything else
