Signs of Cold Stress in Mexican marigold
Symptoms
Mexican marigold tolerates cool conditions moderately and flourishes optimally when temperatures exceed 68℉. In winter, maintain temperatures above 50℉. If temperatures drop below 32℉, foliage may begin to sag. Mild cases can recover, but severe instances lead to wilting and eventual leaf drop.
Solutions
Remove any parts damaged by frost. Before subsequent cold spells, cover the plant with materials like non-woven fabric or cloth, and erect a windbreak to shield it from chilly gusts.
Signs of Heat Stress in Mexican marigold
Symptoms
In summer, Mexican marigold should be kept 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 midday and afternoon sun, or use a shade cloth for cover. Water the plant in the morning and evening to maintain soil moisture.
