Please help me save my Magnolia
I had purchased and planted a Southern Magnolia tree just 3 months ago (~March 2014) on my front yard in Richmond TX (Zone 8b). I've added some manure while planting along with some loose soil. I've used 6 bags of rubber mulch.
I've been watering frequently and its been raining a fair bit in Houston also. However as you can see in the attached pics, it doesn't look like it is doing well. Am I watering too much? Too little? Or is this some kind of a disease? Will greatly appreciate help.
