Star Magnolia Hasn't Grown
I planted a Star Magnolia in Spring 2010. It is about 4' tall. It bloomed Summer '10 and '11, but then didn't bloom Summer '12. It hasn't grown since I planted it, but it's still alive. I followed all the instructions when I planted it, and I mulch it every year (but not too much). It is in a 'wet' part of the yard, so I don't know if drainage has something to do with it. Should I fertilize it? If so, when? I have always been afraid to put any chemicals on/around it for fear of killing it. Any advice will be much appreciated. Thank you!
