We have had a Leonard Messel Magnolia for about a year and a half and about the end of August first part of Sept. the edges of the leaves have started to turn brown & fold in. Are we doing something wrong or is there something wrong with our plant?

Magnolia trees can be troubled by nutrient deficiencies, and one of the first symptoms is browning of the leaf margins. They're very sensitive to salt damage, either from over-fertilizing or from salt in the water, and they require rich, well-draining, neutral to barely acidic soil. Soil pH in your gardening region is on the low end of the scale (moderately to very acid) so you'll want to buffer this acidity by incorporating organic matter into the planting hole, topdressing with organic mulch material, using a slow-release fertilizer and watering deeply when you do water, to help leach out excess salts. Use compost rather than peat moss - peat is acidic. Hope the above information helps you help your magnolia!
