Pamela (central Alabama): 4 dwarf magnolias (~10 years). One all brown leaves. Two normal. Fourth half green/half brown. Unusual rain last fall. Never brown before. Asks: dead? dying?
Steve: scratch bark with fingernail → green beneath = alive. Check trunk near ground for loose bark/injury. String trimmers/mowers common culprits.
The scratch test is the definitive field viability check. Basal mechanical injury from lawn equipment is a leading cause of sudden tree decline in maintained landscapes.
