Signs of Cold Stress in Bigleaf magnolia
Symptoms
Bigleaf magnolia exhibits moderate resilience to cold and flourishes optimally when temperatures exceed 60℉. Throughout the winter, it should be maintained above 50℉. Should the temperature drop below 40℉, its foliage might begin to sag. In minor instances, recovery is possible, but severe cases lead to wilting and eventual leaf drop.

Remove any parts damaged by frost. Before subsequent exposure to low temperatures, cover the plant with materials like non-woven fabric or cloth, and erect a windbreak to shield it from cold gusts.
