Also, before anyone asks, my flower beds are packed and these tombstones are custom made and huge, I can't put them in the flower beds there's not enough room.
Last year I was in exactly this position. I had grass hydroseeded in the spring and didn't want to kill it with my display. I wound up placing my tombstones right at the edge of the mulched flower beds. I had some standing skeletons and some kneeling ones in the grass and I moved them just a smidge after 2 weeks. The hard part for setting up is the overall 'who goes where' so although initial set up took longer (the yard changed a lot) it was pretty quick to move things 6-12" to the side.Also, before anyone asks, my flower beds are packed and these tombstones are custom made and huge, I can't put them in the flower beds there's not enough room.
