Signs of Cold Stress in Common bean
Symptoms
Common bean exhibits moderate resilience to cool temperatures, flourishing optimally between 65℉ and 85℉. In colder months, maintain temperatures above 55℉. Should the temperature drop below 40℉, foliage may darken. Severe instances can lead to water-soaked tissue death, wilting, drooping, and a gradual browning of leaves.
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. If moved indoors, position it near a south-facing window for adequate light. Supplement with artificial lighting if natural light is insufficient.
Signs of Heat Stress in Common bean
Symptoms
In summer, Common bean should be maintained below 85℉. When temperatures surpass 95℉, plant development decelerates, leaf coloration fades, and susceptibility to sun damage increases.
Solutions
Prune off any sun-scorched and desiccated sections. Relocate the plant to an area offering protection from the afternoon sun. Irrigate the plant in the morning and evening to maintain soil moisture.
