Signs of Cold Stress in Corn marigold
Symptoms
Corn marigold exhibits moderate resilience to cold and flourishes optimally within a temperature range of 60℉ to 70℉. Throughout the winter, it should be maintained above 50℉. Should temperatures drop below 40℉, foliage may darken. In extreme instances, water-soaked tissue death, wilting, and drooping might occur, with leaves progressively turning brown.
Solutions
Remove any parts damaged by frost. Promptly relocate the plant indoors to a warm setting or construct a temporary greenhouse for protection against cold. When bringing the plant inside, select a spot near a south-facing window to guarantee sufficient sunlight. If light is inadequate, supplementary lighting can be utilized.
