I have been babying along a southern magnolia for 8 years although I live in zone 6, Philadelphia, because others in my neighborhood have succeeded. I was hoping for flowers finally this year; instead March winds have nearly killed the tree. I am guessing from descriptions I found online that the tree is suffering from dessication due to the wind. My neighbor installed a board fence next to the tree last summer, which probably contributed to the draft on it. My question is whether to give up on the tree and get out my chainsaw. The tree is brown from the top down to the last two feet of the bottom branches. We have had extensive rain this spring but the tree doesn't show much sign of rebounding. Am I too impatient? I hate killing any garden plant but this is pretty sad looking.
