Signs of Cold Stress in Common holly
Symptoms
Common holly tolerates cold moderately and flourishes optimally when temperatures exceed 60℉. In winter, maintain temperatures above 50℉. If temperatures drop below 40℉, foliage may begin to sag. Mild cases can recover, but severe cases lead to wilting and eventual leaf drop.
Solutions
Remove any parts damaged by frost. Before further cold exposure, cover the plant with materials like non-woven fabric or cloth, and build a windbreak to shield it from chilly gusts.
Signs of Heat Stress in Common holly
Symptoms
In summer, Common holly should be kept below 75℉. When temperatures surpass 80℉, leaves lighten in color, tips may dry and shrivel, leaves might curl, and the plant becomes more prone to sunburn.
Solutions
Prune off any sun-scorched and desiccated sections. Relocate the plant to a spot offering protection from intense midday and afternoon sun, or use a shade cloth for cover. Water the plant in the morning and evening to maintain soil moisture.
