Signs of Cold Stress in African marigold
Symptoms
African marigold tolerates cool temperatures moderately and flourishes optimally when temperatures exceed 68℉. In winter, maintain temperatures above 60℉. If the temperature drops below 50℉, foliage may begin to sag. Minor cases allow recovery, but severe instances lead to wilting and eventual leaf drop.
Solutions
Remove any parts damaged by frost. Before subsequent 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 African marigold
Symptoms
In summer, African marigold should be maintained below 77℉. When temperatures surpass 86℉, leaf coloration lightens, leaf 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 the midday and afternoon sun, or use a shade cloth for cover. Irrigate the plant in the morning and evening to maintain soil moisture.
