I'm based in Melbourne and planted two Magnolia grandiflora 'St Mary' Pleached trees in late 2018 and I'm struggling to figure out what has gone wrong with the obvious one on the left-hand corner. I'm guessing the other one is closer to the house and cops less wind. Should I get rid of it or persist? Some of the leaves curl and brown on the tips. Thinking of removing the Lambs Ears below as they keep getting out of control and probably suffocate the base of the plant. Has anyone had this problem before?
Should the Magnolia go?
