How far apart to plant trees/climbing rose
I suspect that my landscaper may be planting 2 carolina laurel cherry trees too close together (see photo below). Note the drip system plumbing to the right of the trees, which is why he has to bunch them together closer than the design called for. Would this be a problem and should I ask him to move them further apart?
Also, this is causing the 2 trees to be really far from the climbing lady banks rose to the right (the skinny stake against the fence, about 15 feet to the right of the trees. Should I try to fill the void in-between or leave it for the lady banks rose to fill up? I had read that the rose can take over quite a large area, but not sure if it will cover the size of the space that's currently empty.
