Q.Sparse Magnolia
My young magnolia looks scruffy to me. Is there something I need to do to help this tree, please?

I notice that the grass around it is quite green. I'd test the soil for too much nutrients. It looks like nutrient burn. IF it gets watered more than other spots, I'd test for oversaturation. This could suffocate the roots. Either way, a soil test should give you a good starting point.
