Tiles Overwriting wihout multiple layers

hey guys, can you help me ?
i want to add tiles in one layer without overwriting it eg. i want to place a tree in front of another tree
do i have to use more layers or is there a more elegant way to do it
the tree tiles are 2*3

i solved this in the 2nd picture by using another layer, but is this necessary?

The easiest way to achieve this is to have a single tile for your tree (or two high tiles next to each other), instead of having it consist of 2x3 tiles. Tiled will let tiles that are larger than the grid extend at the top and to the right, which usually leads to the expected overlapping behavior.

To get a single tile for the entire tree, you’ll need to either move it to a separate tileset along with other tiles of that size, or you can save it as its own image entirely and then use it in a “collection of images” tileset.
