When it comes to rose petals at ceremonies, in my opinion, you've got to go big or don't do any at all. It is super important to express to your florist that you want to order petals on the heavy side to make sure it is long enough for your aisle. Even better, find a photo to show them how you would like the petals displayed.
If you are having an outdoor wedding, arrange with your florist to be on-site 30-45 before your ceremony start time so that she can set-out the petals. If you are getting married on a cliff, over-looking the beach, and you have noticed that it has always been super windy on prior visits...that may be a sign to fore-go the petals.
Getting married indoors you can avoid this problem all together.
Rose petals down aisles are BEAUTIFUL when done correctly, nothing bothers me more than when an aisle looks like the petals look as though they were left over from yestereday's ceremony.
