The tips of my flower petals are going brown. They're in water and in a cool place. However, they are not in the fridge because I heard that if you place the flowers next to fruit and vegetables they die due to the release of ethylene. How can I stop this from occuring next time?
Definition of WEDDING
1: a marriage ceremony usually with its accompanying festivities : nuptials
2: an act, process, or instance of joining in close association
3: a wedding anniversary or its celebration!
Hence a 2nd wedding forum isn't JUST for ppl getting married again!

Re: How come the tips of the petals on my flowers are going brown?
Have a bucket or container ready with a few inches of water, and floral preservative. Trim the stems at an angle, about 1/2 an inch.
Remove all the foliage/leaves below the water level.
If you want the roses to open up sooner, peel the outer petals off. If you don't want them to open up, leave them. (If the roses come tightly packaged, leave them in the packaging, but still trim the ends and get them into water -if you don't want them opened up as soon).
Keep them cool, out of drafts, out of sunlight. If you can't avoid a draft, loosely/lightly cover them with lightweight plastic, like a dry cleaners bag. Avoid handling or touching them as much as possible.
Thanks guys, you all rock! : )
Next time I will do everything that you have all suggested.
