Signs of Cold Stress in American plum
Symptoms
American plum tolerates cold moderately and flourishes optimally when temperatures exceed 65℉. In winter, maintain temperatures above 50℉. If temperatures drop below 32℉, leaves might begin to sag. Minor cases may recover, but severe instances lead to wilting and eventual leaf drop.
Solutions
Remove frost-damaged sections. Before subsequent cold exposure, cover the plant with materials like non-woven fabric or cloth, and erect a windbreak to shield it from chilly gusts.

Symptoms
In summer, American plum should be kept below 75℉. When temperatures surpass 85℉, leaf color fades, tips may dry and shrivel, leaves might curl, and the plant becomes more prone to sunburn.
Solutions
Cut off any sunburned and desiccated portions. Relocate the plant to a spot offering protection from midday and afternoon sun, or use a shade cloth for cover. Water the plant in the morning and evening to maintain soil moisture.
