How do i scatter petals with no flower girl?

You could still have your bridesmaids scatter them, but instead of a basket, just have a small pouch that they carry with their bouquet. They can reach into the pouch and take petals out while they walk.

I didn't want to have a ring bearer or flower girl for our wedding, so we decided to ask one of our groomsman to be our "flower guy" and he did agree.
Are you being escorted down the aisle?

What about parent(s) who can play the part, if you think they would be up to it?
Maybe if someone is escorting you down the aisle once you reach a certain point you both stop, whomever might be walking with you, begins to "quickly" start tossing petals down the rest of the aisle because he/she notices there are none, and then returns to you (as you have remained stationary) in which then you both continue walking down the rest of the aisle "like normal".

I haven't had experience with it, but you could always just have them practice and see if it would be a problem. If it is, then you could go with the other suggestions above about having a mail friend do it, or even your parents.

Personally, we're skipping it to save on clean up time and I don't find it necessary, but if you want it then there's def. options!

You could also have a small basket at the end of every other pew and sit people there that are comfortable with tossing them? That would be a cute way to include your guests in the ceremony!

No problem! I hope you find the solution that works best for you!

Having the groomsmen do it is a hilarious idea! Do you have a MOH? You can always ask for her to do it since she usually goes down the aisle last & right before the bride, then they won't have been stepped all over by previous bridesmaids.

I think this idea makes the most sense, as long as what you really want is the end result of flowers in your aisle.

Could you have them laid put ahead of the ceremony? Yes, everyone walks on them then but you still get the photos and feel for you. Otherwise I would have your bridesmaids do it.

Many florists will make an aisle of petals before guests arrive and then they enter from the outside instead of the middle to be seated. I would ask them before I ask a bridesmaid to toss petals.

Do you have a wedding coordinator, someone at the church/event site who is coordinating who can do it? or Ushers or like others have mentioned having them down prior to opening the doors?

Yes I have been to many weddings where they were just already there before the ceremony, and takes the awkwardness out of making any adults do it
