Question on tree planting

[Tangy_Cat]

I am planning on creating an orchard in my AC town and I was wondering if trees could be planted on the bottom right of rocks?

What do you mean? As far as I've learned, trees can't be placed in any way adjacent to immovable objects.

Yeah, it seems that trees can only survive if there is nothing within one space all around them.

I miss the feature where trees could grow diagonally of each other in the original...
But I could see why that would cause a problem.

You mean like this?:
X = empty space
R = rock
T = tree
